MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

1.2 BACKGROUND

1.2.1 Locality

The Matzikama Municipality falls within the boundaries of the West Coast District Municipality. Please refer to Figure 1 below for the location of the Matzikama Municipality within the West Coast District Municipality.

Figure 1: Matzikama Municipality Locality Map

The Matzikama Municipality is a category B municipality proclaimed in terms of Provincial Notice No 481/2000 of September 2000. As of the last local government elections in May 2011, the previous district managed area to the north of the Matzikama has been incorporated as per notice in the Provincial Gazette Extraordinary 6825. As a result, the geographical area of the municipality increased form roughly 8 000 km2 to 14 000 km2.

The Matzikama Municipality now consists of the eighteen towns or villages, namely Vredendal, Vanrhynsdorp, Klawer, Trawal, Lutzville, Lutzville West, Ebenhaezer, Koekenaap, Papendorp, Doringbaai, Strandfontein, Nuwerus, Bitterfontein, Kliprand, Put-se-Kloof, Rietpoort, Molsvlei and Stofkraal.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 2 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

Vredendal is the primary service centre. Klawer, Vanrhynsdorp and Lutzville are regarded as secondary towns each with their own business districts. Klawer and Lutzville are located adjacent to the Olifant’s River, while Vanrhynsdorp is located on the N7 at the turnoff on the road to Upington.

Doringbaai and Strandfontein are towns on the Atlantic Coast, the latter being a well-known holiday resort. Ebenhaezer, Koekenaap and Papendorp are smaller villages.

The municipality falls within the Olifants/Doorn Water Management Area (WMA). The major river in the WMA is the Olifants River, of which the Doring River (draining the Koue Bokkeveld and Doring areas) and the Sout River (draining the Knersvlakte) are the main tributaries. The life-giving arterial, namely the Olifants River, with is associated canal systems supports a flourishing agricultural sector.

1.2.2 Existing Bulk Water Supply

The Olifants River Water Scheme is the main water source for Klawer. The water scheme consists of a series of canals and is owned by DWA and operated by the Lower Olifants River Water User Association (LORWUA).

Raw water is extracted from the Olifants River Water Scheme canal, from which water is pumped to a 2 Ml raw water storage dam. Water is also abstracted from a borehole and pumped to the raw water storage dam.

From the raw water dam, water is pumped through the water treatment works, where the water is treated by means of four (4) slow sand filters and chlorination. Treated water is pumped to a 1.5 Ml reservoir which supplies bulk water to Klawer’s Area 3 Low Water Zone. A pump station located next to the 1.5 Mℓ reservoir, supply bulk water to another 1.5 Mℓ reservoir, from which water gravitates to Klawer’s Area 3 High Water Zone and to a 530 kℓ reservoir. Water gravitates from the 530 kℓ reservoir to Klawer’s Areas 1 and 2 Low Water Zone and Areas 1 and 2 High Water Zone.

Please refer to Figure 2 below for a schematic layout of the Klawer water supply system.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 3 2012-06-07

Figure 2: Klawer Schematic Layout Water Supply System

Please refer to the Technical Investigation Report in Appendix A, for more detail on the existing water supply system.

1.2.3 Bulk Water Supply Requirements

The need for the proposed bulk water infrastructure project arose due to a proposed new low income housing development that will comprise a total of 650 erven.

For further technical details, please refer to the Technical Investigation Report in Appendix A.

2. STRATEGIC AND PLANNING ISSUES

2.1 ALIGNMENT WITH IDP AND WSDP

The Matzikama Municipality recently drafted the Water Services Development Plan (WSDP) for the 2012/2013 financial year. The draft WSDP will be presented to Council for approval end of June 2012. After approval of the 2012/2013 WSDP by Council, a Council Resolution with regards to the approval of the WSDP will be submitted to DWA.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 4 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

The WSDP is aligned and integrated with the 2012-2017 IDP of Matzikama Municipality and forms an integrated part of the IDP public participation and consultation process. The IDP is predominantly strategic as opposed to the WSDP, which is more operationally orientated.

Reference to this proposed bulk water infrastructure project is made in the WSDP in Module 3, Topic 5. Please refer to Appendix B for the Executive Summary of Matzikama Municipality WSDP for 2012/2013 financial year.

2.2 ALIGNMENT WITH PDGDS, WFGD AND TURN AROUND STRATEGY

The iKapa Growth and Development Strategy commits the Western Cape Province to the following five long-term goals to guide policy-making and resource allocation: i) Grow and share the economy ii) Build a more equal and caring society where poverty is eradicated. iii) Promote ecologically sustainable development iv) Foster greater spatial integration v) Ensure effective governance and institutional strengthening

The IDP of Matzikama Municipality (which incorporates the WSDP as one of the Sector Plans), has compiled its strategies in line with these objectives. The proposed bulk water infrastructure project for Klawer will particularly contribute in achieving goals I and II of the iKapa Growth and Development Strategy.

DWA is developing a framework to guide actions and decisions that will ensure water security in terms of quantity and of quality to support South Africa’s requirements for economic growth and social development. Sufficient supply of water is a requirement for the country to achieve its economic growth targets. The provision of water to every person in South Africa is also a fundamental goal that needs to be facilitated by the department’s framework. These two goals must be achieved without compromising the ecological sustainability of water resources. The proposed bulk water infrastructure project for Klawer is in line with the goals of the Water for Growth and Development Framework.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 5 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

In December 2009, the South African Cabinet approved a comprehensive Local Government Turnaround Strategy (LGTAS). One of the main aims of the LGTAS is to renew the vision of developmental local government. To do this the LGTAS seeks to improve the organisational and political performance of municipalities and in turn the improved delivery of services.

The proposed bulk water infrastructure project for Klawer is aligned with the goal of the LGTAS which is to improve the lives of citizens, and progressively meet their social, economic, and material needs and thereby restoring community confidence and trust in government.

2.3 ASSOCIATED WATER INFRASTRUCTURE

Please refer to Section 1.2.2, Figure 2 for a schematic layout of the existing Klawer bulk water supply system. The proposed bulk water infrastructure project is for an upgrade to the existing bulk water supply system to provide sufficient bulk water supply to the proposed low cost housing development in Klawer. Please refer to section 6 of the Technical Investigation Report included in Appendix A for a description of the capacity of the existing bulk water infrastructure. The upgrades required on the existing bulk water system are described in section 9 of the Technical Investigation Report. Therefore, the associated bulk water infrastructure is already in place.

The Klawer WWTW (Oxidation Pond system) has a capacity of 0.650 Ml/d. The WWTW is currently loaded close to capacity and the upgrading of the Klawer WWTW is currently being investigated by the municipality.

2.4 STRATEGIC IMPORTANCE

The strategic objectives of the Matzikama Municipality as identified in 2012-2017 IDP are:

1. Facilitating the development of the economic wealth of the Matzikama and the reduction of poverty.

2. Strengthening the Matzikama Municipality’s own financial resources to ensure long-term financial sustainability and viability.

3. To ensure an effective, transparent and caring Municipality that is accountable to its citizens.

4. To promote access to adequate, affordable and well maintained municipal basic services.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 6 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

5. Facilitate developing an environment that maximize the social well-being of the citizens of the Matzikama especially the poorest of the poor and other vulnerable groups.

6. Capacitate citizens through effective communication and embracing cultural diversities.

7. Promote responsible and accountable usage of the Municipality’s spatial environment to sustain the natural and built assets.

The key drivers for the proposed bulk water infrastructure project are as follows:

• To accommodate the proposed housing development in Klawer which will consist of a total of 650 erven. The proposed housing development will address the housing backlog. An eventual total of ± 10 501 persons in Klawer, which includes the housing development, will be provided with adequate bulk water supply.

• To improve water quality to comply with the relevant SANS standards by addressing the water quality failures currently experienced at the Klawer WTW.

From the above, it can be noted that the proposed bulk water infrastructure project is in line with strategic objectives 1, 3, 4, 5 and 7.

2.5 TECHNICAL OPTION

A Technical Investigation Report was compiled and the preferred option for the proposed bulk water infrastructure project was determined in consultation with the Matzikama Municipality. Please refer to Appendix A for a copy of this report.

The Matzikama Municipality identified its needs and priorities and accordingly the planned phasing of implementation was determined.

The Matzikama Municipality agreed and accepted the option for the proposed bulk water infrastructure project and appointed WorleyParsons RSA to conduct the Implementation Ready Study in order to obtain the required funding from DWA for implementation. Please refer to Appendix F for a letter from the Municipal Manager confirming approval and support for the preferred technical option.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 7 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

2.6 LEVEL OF SERVICE

As identified in the WSDP, Matzikama Municipality is working towards providing all households in towns with a water connection inside the house and connecting all households to a waterborne sanitation system.

A service level survey was conducted for DWA during May 2011 and was signed off by the Technical and Housing Department of the Matzikama Municipality. Please refer to Appendix C for a copy of the service level survey for Klawer.

Currently 690 households in Klawer are not receiving adequate water services. The proposed bulk water infrastructure project will enable the municipality to provide a water connection inside the house and connect to a waterborne sanitation system. This aligns with the WSDP of the municipality.

2.7 ECONOMIC GROWTH REQUIREMENTS

Investing in infrastructure creates an enabling environment for economic growth and is an important precondition for sustainable growth.

Matzikama Municipality’s local economic development objective is to ensure strategic management services that are effective and fit for purpose and provide a service to the advance of the development of the local economy in the municipal area.

The three largest sectors contributing to the local economy is Agriculture, Finance and Community Services.

It is clear from the Technical Investigation Report that the proposed bulk water infrastructure project is required to enable the proposed housing development in Klawer to continue.

2.8 WATER SCARCITY

The water resources for Klawer is from the Olifants River Water Scheme and the Klawer borehole. The yield from these resources versus the future water demand is discussed in section 6 of the Technical Investigation Report. Please refer to Appendix A for a copy of this report.

The permitted abstraction from the LORWUA canal system for Klawer is 450 Mℓ/year. The permitted abstraction from the borehole is 30 Mℓ/year which brings the total allocations for Klawer to

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 8 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

480 Mℓ/year. The projected water demand for a 25 year design period for Klawer is 1 680 kℓ/day x 365 days = 613 200 kℓ/year (approximately 613 Mℓ/year).

It is estimated that the current allocation is still sufficient for another 7 to 8 years and that an increase in allocation is not required at this stage.

2.9 PROJECT FUNCTIONALITY

There is a significant shortage in raw water storage for Klawer. The proposed bulk water infrastructure project will provide adequate bulk water supply to the proposed low cost housing development. If the bulk water infrastructure is not implemented, the proposed housing development will not be able to continue. This will have a severe impact on addressing the housing backlog in Klawer.

Currently water quality fails with regards to turbidity. Furthermore treated water is corrosive and needs to be stabilized. The proposed improvements to the Klawer WTW will ensure full compliance with the relevant SANS standards.

To accommodate future growth and therefore creating the enabling environment for economic growth, it is crucial that the proposed bulk water infrastructure project is implemented.

2.10 CAPITAL AND OPERATING COSTS

Capital and operating cost estimates for the implementation phase of the proposed bulk water infrastructure project are included in section 10 of the Technical Investigation Report. Please refer to Appendix A for a copy of this report. Costs are based on current market related rates and need to be escalated on an annual basis.

There is a significant shortage in raw water storage for Klawer. The existing raw water storage is not sufficient to meet the current demand. By implementing the proposed project, sufficient raw water storage will be provided for a 15 year design horizon. Therefore it is estimated that a total of 1993 households will be supplied with sufficient bulk water infrastructure.

A capital cost of R25 669 836.00 (incl. P&G, Fees and VAT) is estimated for the implementation phase. The capital cost per household that will be serviced by the proposed bulk water infrastructure project is therefore R12 880 per household.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 9 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

According to Table 49, Capital Costs per Household for Water Supply, in section 7 of Municipal Infrastructure: An Industry Guide to Infrastructure Service Delivery Levels and Unit Costs: June 2010, the capital cost per household for a scheme of 5 000 people in the Western Cape is R23 334 per household.

The capital cost per household for the proposed bulk water infrastructure project is significantly lower and can be contributed to savings due to existing infrastructure already in place.

An annual operation and maintenance cost of R233 800.00 is estimated for the proposed infrastructure. Based on the current annual water consumption of 338 841 kl/a, the unit cost of operation and maintenance is 69 c/kl.

2.11 AVAILABLE CO-FUNDING

The Matzikama Municipality is committed to co-fund the proposed bulk water infrastructure project. Please refer to section 7 (Financial Criteria) for more details on the co-funding arrangement for this project.

3. SOCIAL CRITERIA

3.1 BASIC SERVICES BACKLOGS

The Matzikama Municipality is working towards providing all households in towns with a water connection inside the house and connecting all households to a waterborne sanitation system.

The current service levels for Klawer with regards to potable water supply are as follows:

No. of Households Klawer Housing Need (communal services) 106 Backyard dwellers in formal areas 540 Housing need (residing on farms) 44 Adequate 1 452 Total 2 142

Households in the informal areas with existing communal services will be provided with a water connection inside the house.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 10 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

The proposed bulk water infrastructure for Klawer will enable a water connection inside the house to an eventual ± 10 501 persons.

3.2 POOR HOUSEHOLDS TO BE SERVICED

The Matzikama Municipality’s definition of a poor household is as follows:

“A household where the total monthly income of all the residents older than eighteen (18) years is less than that of a needy household. The limit for a household to qualify is two times the social pension.”

Poor households who cannot afford basic services are identified as being indigent and benefit from the indigent support system.

Households qualify for support by completing a specific application form after which approval and further auditing is required before a household can be classified as indigent to receive benefits. Approved applications of indigent households are reviewed regularly by Council to ensure only needy households are registered and receive benefits.

The number of indigent households in Klawer was 366 on 31 January 2012.

Please refer to Appendix D for a copy of the Matzikama Municipality’s Credit Control Policy. The municipality’s policy with regards to support to indigent households is set out in its Indigent Policy.

3.3 JOB CREATION

The following table project the possible job creation for the entire project:

3.4 AFFORDABILITY OF PROPOSED WATER TARIFFS

The unit cost of water to meet the operational and maintenance expenses of the proposed bulk water infrastructure project is estimated in section 10 of the Technical Investigation Report included in Appendix A.

A key constraint in planning for infrastructure delivery is household affordability. Knowing the existing situation regarding household incomes is a key part to understanding consumers’ affordability levels. The incomer earnings per household are an indicator of purchasing power of communities and reflect their standard of living, which in turn has implications for the future growth potential and need for certain types of social / commercial services

The information below is from the 2001 Census data and can be used by the municipality as an indicator when determining tariffs:

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 12 2012-06-07

From the table above it can be noted that the typical water and sanitation bill is still less than 10% of the household monthly income for consumers in Klawer. The additional 69 c/kl required for operation and maintenance purposes is therefore regarded reasonable and affordable.

The Matzikama Municipality undertake to address the changes in its water tariff structure in the next budget year in order to recover the additional 69 c/kl to cover the additional operation and maintenance costs. The municipality endeavour to increase the number of blocks in the tariff structure and will thereby:

• Recover additional costs for operation and maintenance costs, especially through the higher usage blocks.

• Promote the efficient use of water and therefore effectively implementing Water Demand Management.

3.5 CONTRIBUTION TOWARDS POVERTY ERADICATION

The proposed bulk water infrastructure project will enable the proposed housing development in Klawer to be implemented which will contribute substantially towards the eradication of housing backlogs in Klawer. The proposed housing development will provide housing to households currently living in informal settlements and as backyards dwellers and thereby contributing towards poverty eradication, better hygiene and living conditions.

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

4.3 SMME AND BEE ENTERPRISES TO BENEFIT

Labour intensive techniques will be applied for the civil works which will include site clearance, minor earthworks, laying of pipelines and other general civil works which are deemed feasible for labour intensive work.

A target value of 5% of the total works will be implemented via the Extended Public Works Programme (EPWP), approximately R1.1 Million (incl VAT) based on the capital cost estimate for the works.

All unskilled labour will be sourced from local resources within the Matzikama Municipal Area. Skilled labour will be sourced from the local municipal area where possible.

The Matzikama Municipality’s Supply Chain Management Policy promotes Broad Based Black Economic Empowerment (BBBEE) for this project. The Preferential Procurement Regulations further requires that 10 points of the total evaluation are for the BBBEE profile of the company, therefore incentivizing the promotion of BBBEE enterprises.

Maintenance of the proposed bulk water infrastructure will create additional employment over the full life-cycle of the project. Mechanical, electrical and civil maintenance will be done locally as far as possible, with specialised repair and maintenance work being outsourced only when it cannot be done within the local municipal area.

Indirectly, all existing and future SMMEs and BBEEE enterprises will benefit from the project. The proposed bulk water infrastructure project will provide reliable bulk water supply to Klawer. The implementation of the project is a prerequisite for the approval of all planned commercial, industrial and housing developments, and will therefore also benefit SMMEs and BBBEE enterprises.

4.4 REGIONAL BENEFIT

The IDP identifies the proposed low cost housing development as a priority. The proposed bulk water infrastructure project will enable the proposed housing development to continue and will therefore fulfil the priorities of the IDP.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 16 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

5. TECHNICAL CRITERIA

5.1 MASTER PLANNING

The proposed low income housing development in Klawer has been identified in the Water Master Plan for Matzikama Municipality, which was compiled by CEs in February 2005.

5.2 APPROPRIATENESS AND ACCEPTABILITY

Please refer to the option analysis in section 7 in the Technical Investigation Report included in Appendix A.

As per the reconciliation strategies, to supply sufficient potable water to Klawer, the following options are recommended, in order of priority and implementation sequence:

1. Full implementation of a Water Conservation and Water Demand Management Strategy.

2. Additional supply from Olifants River Government Water Scheme.

3. Re-use of water

4. Groundwater development.

The Matzikama Municpality already has a Water Demand Management Strategy in place and is already implementing various WC/WDM initiatives. The next option for provision of bulk water supply is additional supply from the Olifants River Government Water Scheme. Since the permitted allocation from the Olifants River Government Water Scheme is still sufficient for another 7 to 8 years, this option is deemed to be the most appropriate.

5.3 WATER RESOURCE

As identified in the Technical Investigation Report, adequate water resources are available from the Olifants River Water Scheme, if the municipality can successfully implement the Water Conservation and Water Demand Management (WC/WDM) Strategy in order to minimise water losses. The reconciliation strategies compiled as part of the All Town Study recommends WC/WDM interventions as a first priority and increased supply from Olifants River Water Scheme as a second priority. Further development of groundwater resources is not feasible at this stage.

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

5.4 WATER DEMAND MANAGEMENT AND CONSERVATION

As identified in the WSDP, Matzikama Municipality’s initial focus should be to reduce the water losses and inefficient water use. The percentage water losses is one key performance indicator which the municipality can use to measure how well the system is managed. Matzikama Municipality should work towards reducing their water losses for the Klawer distribution system from more than 29% to not more than 15%.

Matzikama Municipality improved its meter reading data drastically over the last two years in order to monitor the percentage of water losses.

The Municipality distributes public notifications and high on the list of priorities in these communications, mostly through newsletters, is how to conserve water and reduce wastage.

Standby teams are also available after hours and over weekends, in addition to the planned and scheduled Operation and Maintenance (O&M) activities, in order to allow for unscheduled responses to service breakdowns due to malfunctioning equipment, vandalism, emergency situations, etc.

The main WDM interventions implemented by the municipality over the last few years are as follows:

• Water Master Plans were drafted for all the towns during 2005.

• Customer Services and Complaints System is implemented by the municipality (burst pipes, etc.). Standby teams are also available after hours and over weekends for immediate repairs and burst pipes.

• Strict municipal services standards for the installation of new water reticulation networks for own and private developments.

• Reticulation material and quality standards checks.

• Meter and record all bulk water supply to the various distribution systems and improve the quality of data on the monthly consumer usage in order to carry out more detailed water balances for the various systems.

• Re-use of treated effluent from the Vredendal and Vanrhynsdorp WWTW for irrigation purposes.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 18 2012-06-08

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

• Installation of prepaid water meters.

A WDM Strategy was also drafted for the municipality in December 2007 by CES, with funding support from DWA. The purpose of the strategy was to further conserve and protect available resources and to ensure the effective utilisation of the available water resources.

The following implementation phases of the WDM strategy are recommended:

Component Chronological stepwise approach 1) Clean billing data, update SWIFT, verify/address metering and non- payment CAFES cost and 2) Introduce lBR structure to all residential consumers, but limit price change pricing strategy 3) Set IBR structure = 6 blocks, mm/max steps for 6 kl/month/100 kl/month (CPP) 4) Set price of water in max block (above 100 kl/month) to at least R15/kl 5) Introduce informative billing 1) Measure water volume that is lost 1a) Raw water supply and treatment 1b) Distribution system 1c) End user meter problems 2) Identify and quantify losses 2a) Raw water supply and treatment Leakage 2b) Distribution system management programme (LMP) 2c) End user meter problems 3) Conduct operational and network audit 3a) Raw water supply and treatment 3b) Distribution system 3c) End user meter problems 4) Improve performance: upgrade network, design action plans 5) Sustain performance with good staffing/organisation structures 1) Schools WDM programme Socio-political 2) Public awareness programme programme (SPP) 3) Non-payment issues 4) Encourage users to implement WCP at their own expense 1) Repair on-site (plumbing) leaks Water conservation 2) Reduced toilet flush volume products (WCP) 3) Xeriscaping garden areas (water wise gardening) 4) Other methods to reduce consumption by changing human habits Reuse of waste 1) Identify large water consumers water (RWW) 2) Communicate advantages / incentives of reuse practice to large

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 19 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

Component Chronological stepwise approach consumers 3) Information gathering on current status of reuse measures 4) Installation of reuse practice 5) Monitor future water consumption

The current water losses for the Klawer distribution system, is more than 29 %. By implementing the abovementioned WC/WDM strategies the municipality can lower the water losses to 15%.

Some specific items of the proposed WDM Strategy are considered to hold significant promise. These items should receive priority and are the backbone of the municipality’s WDM Strategy.

• Meter and record bulk water supply (monthly).

• Improve quality of data regarding consumer use (monthly).

• Initiate a WDM communication campaign to report on what the Municipalities have achieved (Lead by example).

• Immediately implement the CAFES-pricing policy programme for residential use by conducting a detailed price elasticity study, applicable to MM.

• Extend the implementation of the CAFES-pricing policy by a) evaluating the impact of price changes in different Western Cape municipalities and b) implementing a new pricing / tariff structure where the first block is free and the last block is charged at a rate which severely discourages use above 100 kl/month.

• Investigate water saving at sports grounds by means of purified sewerage water irrigation.

• Implement a schools WDM programme.

• Implement water saving by individual large water users through reuse of wastewater.

• Monitor progress of the WDM process.

It is also important for the municipality to continue with the reading of all their bulk water meters. The bulk meters and meter chambers also need to be properly maintained and the meters need to be protected from vandalism.

The Long-Term WC and WDM Strategy for Cederberg Municipality, with which DWA supported them during 2011, can also be implemented by the Matzikama Municipality. This WC and WDM strategy is summarised in the Matzikama Municipality WSDP for the 2012/2013 financial year.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 20 2012-06-08

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

The Matzikama Municipality is committed to get an approved WC and WDM strategy in place and to implement the strategy. The municipality further commit to allow in its budget for the implementation of the WC/WDM strategy.

5.5 BULK DISTRIBUTION

The Matzikama Municpality already has a Water Demand Management Strategy in place and is already implementing various WC/WDM initiatives. The municipality is committed to adopt a formal WC/WDM strategy and to budget for full implementation of the strategy.

The Matzikama Municipality is already implementing various WC/WDM initiatives. The next option for provision of bulk water supply is additional supply from the Olifants River Government Water Scheme. Since the design demand to be supplied by the proposed bulk water project is still within the permitted allocation for another 7 to 8 years from this resource, this option is deemed to be the most appropriate

The existing bulk water infrastructure which extracts water from the Olifants River Government Water Scheme needs to be upgraded in order accommodate the future demand. Since the existing bulk water infrastructure is already in place, upgrading the infrastructure on the existing reservoir sites and servitudes is the optimal choice for bulk distribution for the project.

Therefore existing pump stations will be upgraded, existing pipeline routes and existing reservoir sites will be utilised as far as possible. This will result in capital cost savings where existing infrastructure can only be expanded as necessary.

5.6 TECHNOLOGY

Technology selected for the preferred option is widely accepted in the industry and implemented on other projects in the Mazikama municipal area and other municipal areas around the country.

For the reservoir, a reinforced concrete structure is proposed. This will be a further phase with regards to storage capacity to the existing reinforced concrete reservoirs in Klawer.

For the WTW and pump stations, no new technology or materials is proposed, since work on these components entails upgrade and refurbishment of the existing infrastructure only.

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

The municipality endeavour to explore all possible sources with regard to counter funding required for the proposed project.

The new bulk water infrastructure will be operated and maintained under the municipality’s operating budget. An annual operation and maintenance cost of R233 800.00 is estimated for the proposed infrastructure. Based on the current annual water demand of 338 841 kl/a, the unit cost of operation and maintenance is 69 c/kl. The municipality will recover the additional cost for operation and maintenance by adjusting its tariff structure as part of the new budget.

7.4 AFFORDABILITY

The annual estimated operation and maintenance cost associated with the proposed bulk water infrastructure project is calculated in the Technical Investigation Report (Please refer to Appendix A). The estimated unit cost of water associated with the proposed bulk water infrastructure project is 69 c/kl.

From the table included in section 3.4 it can be noted that the typical water and sanitation bill is still less than 10% of the household monthly income for consumers in Klawer. The additional 69 c/kl required for operation and maintenance purposes is therefore regarded reasonable and affordable.

• Recover additional costs for operation and maintenance costs, especially through the higher usage blocks.

• Promote the efficient use of water and therefore effectively implementing Water Demand Management.

7.5 PROPOSED WATER TARIFFS

As indicated in section 6.13 it can be noted that the level of payment for municipal levies is relatively high at 97% The municipality is committed to continue implementing its Credit Control and Debt Collection By-Law to sustain this level of payment.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 3 - Irs\26202v002rev01.Docm Page 31 2012-06-07

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

The Matzikama Municipality will address the changes in the tariff structure as part of the 2012/2013 budget to recover the additional 69 c/kl required for operation and maintenance of the new bulk water infrastructure.

7.6 FINANCIAL VIABILITY

Addressing the housing backlog in Klawer will be restricted if the proposed bulk water project is not implemented. It was shown in the preceding sections of this report that the project capital costs can be successfully sourced from both RBIG funding and the municipality’s own funds. Operation and maintenance can be accommodated by adjusting the tariff structure. The unit cost of water associated with this project is affordable and regarded as reasonable considering the associated benefits.

Considering the enabling environment that is created for addressing the housing backlog and economic growth, the project is considered financially viable.

7.7 FINANCIAL STATUS AND CREDIT WORTHINESS

The municipality received R169,110 million revenue for the last financial year of which R157,809 million was utilized for operating expenditure. Salaries and Councillor allowances were 33,32% of the operating expenditure for the year under review and the percentage is well within the national norm of between 35-40%. Bulk purchases of water and electricity and expenditure with regards to salaries and allowances makes up most of the total operating expenditure of the municipality. Grant and subsidies received, property tax and service charges, account for most of the revenue for the year under review.

Of the total operating revenue of R169,110 million, a total of R68,182 million was received from grants and subsidies. The municipality is more reliant on grants to finance expenditure than other municipalities with the same nature, due to the limited revenue raising capacity.

The table below indicates the municpality’s liquidity ratios for the last four financial years:

Financial Year Net current assets (R’000) Net current liabilities (R’000) Ratio 2007/08 25 419 19 615 1.3:1 2008/09 37 921 26 361 1.4:1 2009/10 38 994 28 389 1.4:1 2010/11 37 696 42 237 0.9:1

MATZIKAMA MUNICIPALITY IMPLEMENTATION READY STUDY RBIG REPORT PHASE 3: KLAWER BULK WATER INFRASTRUCTURE

The ratio is currently below the national norm of 1.5:1. The municipality is committed to develop and implement more vigorous revenue raising initiatives, especially with regard to outstanding debtors to improve cash flow generation.

8. LEGAL CRITERIA

8.1 WATER USE LICENSE

The current permitted allocation from the LORWUA water scheme for Klawer is sufficient for another 7 to 8 years, if WC/WDM initiatives are successfully implemented. Therefore it is not required to apply for an increased allocation at this stage.

8.2 ENVIRONMENTAL AUTHORISATION

The environmental impact assessment (EIA) has commenced and is still in progress.

An application for Environmental Authorisation was submitted to the provincial Department of Environmental Affairs & Development Planning (DEA&DP). The DEA&DP acknowledged receipt of the application. The initial registration and commenting period for Interested and Affected Parties (I&AP) was completed. The draft Basic Assessment Report was compiled and was put forward for a 40 day commenting period to all registered I&APs.

It is expected that the Environmental Authorisation will be obtained during October 2012. It is not anticipated that any problems will be experienced in obtaining the environmental authorisation and therefore the risks for approving the funding before the EIA is completed is considered very low.

8.3 LAND AND PROPERTY RIGHTS

Land and property rights issues will be addressed as part of the implementation phase. The majority of the proposed bulk water infrastructure is expected to be constructed in existing servitudes.

No problems are anticipated in addressing land and property rights issues.

9. SUSTAINABILITY CRITERIA

9.1 FINANCIAL VIABILITY

The liquidity ratio of the Matzikama Municipality is currently below the national norm of 1.5:1. Due to limited revenue raising capacity, the municipality rely heavily on grants and subsidies. However the municipality is committed to develop and implement more vigorous revenue raising initiatives, especially with regard to outstanding debtors to improve cash flow generation. The Matzikama Municipality endeavour to explore all possible funding sources to provide the counter funding required for implementation of the proposed bulk water infrastructure project.

Considering the enabling environment that is created for addressing the housing backlog and economic growth, the project is considered financially viable.

9.2 OPERATING AND MANAGEMENT CAPACITY

The implementation institution will be the Matzikama Municipality. The municipality have the necessary capacity to implement the project successfully

The Matzikama Municipality represented by the Mayor and Municipal Manager take responsibility and accountability for the proposed bulk water infrastructure project, from inception to implementation including operation and maintenance. Furthermore, the Technical Services Department will be directly responsible for implementation of the proposed bulk water infrastructure project as well as operation and maintenance of the proposed infrastructure.

Obtaining and securing counter funding to finance the implementation of the proposed bulk water infrastructure project is probably the biggest risk for the success of the project, but the municipality endeavour to explore all possible sources with regard to counter funding required for the proposed project.

The Matzikama Municipality is aware of the fact that, as with most municipalities, there is a shortage of labour and appropriate skill levels. However, the municipality, remains committed to implement its Work Place Skills Plan to provide training to ensure that the required skills are developed and maintained

9.3 ENVIRONMENTAL AND SOCIAL ACCEPTABILITY AND IMPACT

As mentioned in Section 8.2, it is expected that the Environmental Authorisation will be obtained during October 2012. It is not anticipated that any problems will be experienced in obtaining the environmental authorisation.

The project is also identified in the WSDP, which is a sector plan of the IDP. The IDP undergoes a public participation process whereby the public is given the opportunity to comment on the IDP. No objections to the proposed bulk water infrastructure project were received.

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

1. INTRODUCTION

1.1 BACKGROUND

WorleyParsons RSA was appointed by the Matzikama Municipality to investigate and provide technical detail of an additional bulk water scheme in Klawer to cater for long term growth in Klawer and a proposed new low income housing development that will comprise a total of 650 erven.

The proposed project is hereinafter referred to “Klawer Bulk Water Infrastructure”.

The purpose of this report is therefore to determine the water demand resulting from the above-mentioned proposed development and to identify and report on the feasibility of the various options to meet the future bulk water demand.

After the most feasible option has been selected, cost estimates for the proposed bulk water infrastructure and a preliminary implementation schedule are provided as part of this report.

1.2 PROJECT LOCATION

Klawer is situated in the heart of Namaqualand approximately 240 km north of Cape Town and 20 km south-east of Vredendal along the N7 national highway.

Klawer has a relatively flat topography and is situated on the eastern banks of the Olifants River which is the main water source to the area.

The town mainly serves then needs of surrounding farming areas and consist of the higher income area in the central part of town, a lower income area to the north and local businesses.

The area has a Karoo type plant life and climate with very cold winters, low annual rainfall and extremely hot conditions during summer months.

2. WATER DEMAND ANALYSIS

The demographic and associated water demand figures for Klawer used in this study are based on the Matzikama Municipality: Water Services Development Plan (WSDP) 2012/2013. Population figures in the WSDP are based on Census 2001 data. Please refer to Appendix A for the Future Water Demand Projection for Klawer as included in the WSDP.

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

2.1 DEMOGRAPHICS

Matzikama Municipality falls within the Olifants/Doorn Water Management Area (WMA). The major river in the WMA is the Olifants River, of which the Doring River and the Sout River are the main tributaries. The life-giving arterial, namely the Olifants River, with its associated canal systems supports a flourishing agricultural sector.

Vredendal is the primary service centre for the Matzikama Municipality and is by far the largest town in the area.

Vanrhynsdorp along with Klawer and Lutzville could be regarded as secondary towns with established business districts.

The area is dependent on the following economic activities:

• Agriculture

• Processing of agricultural products

• Mining

• Fishing

• Tourism

The key-human development issues facing the municipality include poverty and unemployment.

2.2 POPULATION

Please refer to Table 1 in Appendix B for the projected population figures for Klawer.

Based on Census 2001 data, the total population in 2001 of Klawer was 4 472 of which 3 389 estimated to have been lower income and 1 083 is estimated to have been higher income.

For the purpose of this report, the estimated population growth rate for the higher income group is taken as 1.0 % per annum and for the lower income group, the estimated population growth rate is taken as 2.5 % per annum.

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

Additional to the above-mentioned population growth, a housing scheme is planned for Klawer. The housing scheme consists of 650 erven. It is assumed that 50 % of the eventual beneficiaries of the housing scheme are already living in Klawer in informal housing and as backyard dwellers. For the purpose of this report it is assumed that the new housing development can accommodate 6 persons per erf.

The total projected population of Klawer for 2037 is estimated at 10 501 which relates to an average annual population growth rate for Klawer from 2001 to 2037 of 2.4 %. This aligns with the estimated average annual population growth rates included in the WSDP, which is 2.87 % from 2001 to 2010 and 1.82 % from 2010 onwards.

The projected population of Klawer up to 2037 is summarised below:

% growth Year 2001 2012 2017* 2022 2027 2032 2037 p.a.

3. WATER CONSERVATION AND WATER DEMAND MANAGEMENT

Matzikama Municipality improved its meter reading data drastically over the last two years in order to monitor the percentage of water losses.

The Municipality distributes public notifications and high on the list of priorities in these communications, mostly through newsletters, is how to conserve water and reduce wastage.

The main WDM interventions implemented by the municipality over the last few years are as follows:

• Water Master Plans were drafted for all the towns during 2005.

• Strict municipal services standards for the installation of new water reticulation networks for own and private developments.

• Reticulation material and quality standards checks.

• Re-use of treated effluent from the Vredendal and Vanrhynsdorp WWTW for irrigation purposes.

• Installation of prepaid water meters.

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

The following implementation phases of the WDM strategy are recommended:

Component Chronological stepwise approach 1) Clean billing data, update SWIFT, verify/address metering and non- payment CAFES cost and 2) Introduce lBR structure to all residential consumers, but limit price change pricing strategy 3) Set IBR structure = 6 blocks, mm/max steps for 6 kl/month/100 kl/month (CPP) 4) Set price of water in max block (above 100 kl/month) to at least R15/kl 5) Introduce informative billing 1) Measure water volume that is lost 1a) Raw water supply and treatment 1b) Distribution system 1c) End user meter problems 2) Identify and quantify losses 2a) Raw water supply and treatment Leakage 2b) Distribution system management programme (LMP) 2c) End user meter problems 3) Conduct operational and network audit 3a) Raw water supply and treatment 3b) Distribution system 3c) End user meter problems 4) Improve performance: upgrade network, design action plans 5) Sustain performance with good staffing/organisation structures 1) Schools WDM programme Socio-political 2) Public awareness programme programme (SPP) 3) Non-payment issues 4) Encourage users to implement WCP at their own expense 1) Repair on-site (plumbing) leaks Water conservation 2) Reduced toilet flush volume products (WCP) 3) Xeriscaping garden areas (water wise gardening) 4) Other methods to reduce consumption by changing human habits 1) Identify large water consumers 2) Communicate advantages / incentives of reuse practice to large Reuse of waste consumers water (RWW) 3) Information gathering on current status of reuse measures 4) Installation of reuse practice 5) Monitor future water consumption

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

In Klawer, the volume of raw water extracted and treated water is metered. Readings of the treated water indicate a much higher volume than that of the raw water, which subsequently results in a negative value for water losses. For this reason, the treated water readings are ignored in calculation of the water losses. The water losses calculated based on the raw water readings and water sales data gives water losses of just over 29%.

By implementing the abovementioned WC/WDM strategies the municipality can lower the water losses to 15 %. For the purpose of this report the future target water losses percentage is used to determine the size of required infrastructure. The size of required infrastructure is therefore optimised considering all WC/WDM efforts are maximised by the municipality to reduce water losses to acceptable operating norms.

4. WATER QUALITY

The Matzikama Municipality has a water quality monitoring programme in place and includes the following for the Klawer:

OPERATIONAL SAMPLING Monitoring Intervals and Parameters Raw water pH and turbidity, after filtration pH, treated water pH, turbidity and Sampling : chlorine Intervals : Daily (Morning and Afternoon) COMPLIANCE SAMPLING Distribution system Monitoring intervals Klawer : KL1, KL2 Monthly

The monitoring sampling programme is at the minimum required level to ensure sustained operation and safe-drinking water quality.

Matzikama Municipality makes use of AL Abbott and Associates to conduct the drinking water sampling and analysis (Chemical). Samples are taken at various locations in each of the distribution systems and analysed at the laboratory to determine compliance. The water quality results are loaded on DWA’s BDS via the internet. Once entered the data is automatically compared to SANS 241. This real-time system allows for immediate intervention to rectify any problems. Bacteriological compliance is done by the National Health Laboratory Services in Green Point.

The current process for monitoring water quality within the distribution systems is adequate and no further investigation is required for this project. The Municipality should implement the recommendations of the Process Audit Report for the Klawer Water Treatment Works to improve overall operation and to ensure water quality standards are maintained.

5. EXISTING INFRASTRUCTURE

The Olifants River Water Scheme is main water source for Klawer. The water scheme consists of a series of canals and is owned by DWA and operated by the Lower Olifants River Water User Associations (LORWUA).

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 2 - Feasibility & Prelim Design\26202v01rev01.Docm MJ (semir) Page 9 262020KD0 : 26202KD0 Rev A : 2012-06-07

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

A schematic layout of the Klawer bulk water distribution system is shown below:

Raw water is extracted from the Olifants River Water Scheme canal, from which water is pumped (WTW Pump Station) to a 2 Ml raw water storage dam. Water is also abstracted from a borehole and pumped to the raw water storage dam.

From the raw water dam, water is pumped (WTW Pump Station) through the water treatment works, where the water is treated by means of four (4) slow sand filters and chlorination. Treated water is pumped (WTW Pump Station) to a 1.5 Ml low lying reservoir which supplies bulk water to Klawer’s Area 3 Low Water Zone. A pump station (Reservoir Pump Station) located next to the 1.5 Mℓ reservoir, supply bulk water to 1.5 Mℓ high lying reservoir, from which water gravitates to Klawer’s Area 3 High Water Zone and to a 530 kℓ reservoir. Water gravitates from the 530 kℓ reservoir to Klawer’s Areas 1 and 2 Low Water Zone and Areas 1 and 2 High Water Zone.

The pump stations and reservoirs are functional at all times.

6. CAPACITY OF EXISTING BULK WATER INFRASTRUCTURE

Through this investigation it is clearly noted that certain upgrades should be implemented on the existing external water supply system. The shortfall or surplus in capacity of the existing infrastructure to meet the future demand is outlined in this section. Please refer to Appendix D for layouts of the existing bulk water infrastructure.

Water Resource

The permitted abstraction from the LORWUA canal system for Klawer is 450 Mℓ/year. The permitted abstraction from the borehole is 30 Mℓ/year which brings the total allocations for Klawer to 480 Mℓ/year. The projected water demand for a 25 year design period for Klawer is 1 680 kℓ/day x 365 days = 613 200 kℓ/year (approximately 613 Mℓ/year).

Therefore the current allocation from the LORWUA canal system is insufficient for a 25 year design period. From the water demand projection it is concluded that the current allocation is still sufficient for another 7 to 8 years and that an increase in allocation is not required at this stage.

Water Treatment Works Pump Station

The Pump Station at the Water Treatment Works in Klawer contains three pump sets. The first pump set (Canal Pump) extracts raw water from the canal into the raw water dam. The second pump set (Filter Pump) pumps water from the raw water dam to the slow sand filters and the third pump set (Main Pump) pumps treated water to the 1.5 Mℓ low lying reservoir. The capacity required for the abovementioned pump sets is calculated in the table below:

Average Annual Daily Demand (@ 20 Pump Hours/Day) Canal Pump Set Demand Available Surplus 15 year design period 20 ℓ/s 25 ℓ/s 5 ℓ/s (year 2027) Peak Day Demand (@ 20 Pump Hours/Day) Filter Pump Set Demand Available Shortage 15 year design period 37 ℓ/s 37 ℓ/s 0 ℓ/s (year 2027) Peak Day Demand (@ 20 Pump Hours/Day) Main Pump Set Demand Available Shortage 15 year design period 37 ℓ/s 37 ℓ/s 0 ℓ/s (year 2027)

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

From the table above it can be noted that the pump station capacity is still sufficient for a 15 year design period.

Raw water Storage

To allow for maintenance and repairs on the LORWUA canal system, an annual two week off period is implemented whereby flow in the canal system is discontinued. For this reason raw water storage is required to provide sufficient raw water supply to the WTW during this period. The existing raw water storage dam has a capacity of 2 Ml.

The raw water storage required for Klawer is calculated in the table below:

14 Days at AADD Raw water Storage Demand Available Shortage 15 year design period 20 Mℓ 2 Mℓ 18 Mℓ (year 2027)

From the table above it can be noted that there is a significant shortage in raw water storage capacity of 18 Mℓ for a 15 year design period.

Water Treatment

Please refer to the Technical Report for the Klawer Water Treatment Plant included in Appendix E.

Raw water is treated at the WTW by means of four (4) slow sand filters and chlorination. The capacity of the WTW is 1 728 kwℓ/d hen the filters are operated at 0.2 m3/m2.h. To accommodate peak flows the capacity is 2 592 kℓ/d when the filters are operated at 0.3 m3/m2.h.

The water treatment capacity required for Klawer is calculated in the table below:

Water Treatment Peak Day Demand (@ 24 hours Operating Capacity) Capacity Demand Available Surplus 10 year design period 2 469 kℓ/d 2 592 kℓ/d 123 kℓ/d (year 2022)

From the table above it can be noted that there is a surplus in water treatment capacity of 123 kℓ/d for a 10 year design period.

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

Rising Main from WTW to low lying reservoir

The flow capacity of the existing ∅ 250 mm rising main that supply potable water from the WTW to the 1.5 Mℓ low lying reservoir is 76 l/s at 1.5 m/s flow velocity. The rising main capacity required is calculated in the table below:

Rising Main Peak Day Demand (@ 20 Pump Hours/Day) Capacity Demand Available Surplus 25 year design period 43 l/s 76 l/s 33 l/s (year 2037)

From the table above it can be noted that there is a surplus in rising main capacity of 33 l/s for a 25 year design period.

Reservoir Pump Station

The Reservoir Pump Station supply potable water from the low lying reservoir to the high lying reservoir. This pump station supply the needs of Klawer’s Area 1 & 2 high and low water zone and Area 3 high water zone. The pump station capacity required is calculated in the table below:

Pump Station Peak Day Demand (@ 20 Pump Hours/Day) Capacity Demand Available Shortage

15 year design period l l l (year 2027) 28 /s 28 /s 0 /s

From the table above it can be noted that the pump station capacity is sufficient for a 15 year design period.

Rising Main from low lying reservoir to high lying reservoir

The flow capacity of the existing ∅ 200 mm rising main that supply water to the 1.5 Mℓ high lying reservoir has a capacity of 48 l/s at 1.5 m/s flow velocity. The rising main capacity required is calculated in the table below:

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

From the table above it can be noted that there is a surplus in rising main capacity of 16 ℓ/s for a 25 year design period.

Reservoir Capacity

The existing 1.5 Mℓ high lying reservoir supplies potable water to Klawer’s Area 3 high water zone. As identified in the water master plan, this reservoir will supply water to the Klawer Areas 1 and 2 high water zone and Area 3 high water zone in future. The proposed housing development will be located in the Klawer Areas 1 and 2 high water zone. The reservoir capacity required for these high water zones is calculated in the table below:

Peak Day Demand (24 Hours Storage Capacity) Reservoir Capacity Demand Available Shortage / Surplus 15 year design period 1 522 kℓ 1 500 kℓ 22 kℓ (year 2027)

From the table above it can be noted that there is a shortage in reservoir capacity of 22 kℓ.

Gravity Main

The existing ∅ 160 mm gravity main that supply water from the 1.5 Mℓ high lying reservoir to Klawer’s Area 3 high water zone has a capacity of 32 l/s at 1.8 m/s flow velocity. This gravity main capacity is sufficient to accommodate the proposed housing development that will be located in this water zone.

Another ∅ 160 mm gravity main supplies potable water to the 530 kℓ reservoir and has a capacity of 32 ℓ/s at 1.8 m/s. Therefore the two gravity mains have a combined capacity of 64 ℓ/s to serve the high water zones, which is sufficient capacity for the next 5 to 10 years.

7. OPTION ANALYSIS

As per the All Town Study, to supply sufficient potable water to Klawer, the following options are recommended, in order of priority and implementation sequence:

1. Full implementation of a Water Conservation and Water Demand Management Strategy.

2. Additional supply from Olifants River Government Water Scheme.

3. Re-use of water

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

4. Groundwater development.

The Matzikama Municipality is implementing its Water Demand Management Strategy and it is envisaged that the Municipality will achieve the target water losses of 15 % with full implementation of the WDM Strategy for the 25 year design period.

The total permitted abstraction from the LORWUA canal and borehole is 480 Mℓ/year. According to the water demand projection this allocation is still sufficient for another 5 to 10 years after which the option of increasing the allocation from the Olifants River Government Water Scheme should be considered.

Therefore it is proposed to continue supply from the existing water resources and to implement the additional bulk water infrastructure required.

8. DESIGN CRITERIA

This section summarises the criteria accepted for the sizing and design of the respective infrastructure components. The design standards are according to the Guidelines for Human Settlement Planning and Design.

Design Water Usage

The Average Annual Daily Demand (AADD) is based on projected population figures based on Census 2011 data. The projected population figures for the proposed housing development in Klawer were derived based on an assumed occupancy of 6 c/erf.

The design water usage assumed for the purpose of this report for domestic consumers is summarised in the table below:

Area Unit Demand (ℓ / c / d) - Higher Income 200 - Lower Income 130 - Housing Scheme (650 erven) 60

The design water usage for businesses and other is based on data included in the Future Water Demand Projections for Klawer in Appendix A. As in the Water demand Projections, an allowance has been made for annual growth of 1 % per annum. The design water usage for businesses and other is summarised in the table below:

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 2 - Feasibility & Prelim Design\26202v01rev01.Docm MJ (semir) Page 15 262020KD0 : 26202KD0 Rev A : 2012-06-07

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

Area AADD (kℓ / d) - Businesses ** 106 - Other *** 71

** Businesses in Klawer Areas 1 and 2 assumed to be 50 % of Klawer, therefore 53 kℓ/d *** Other in Klawer Areas 1 and 2 assumed to be 50 % of Klawer, therefore 35.5 kℓ/d

Design Water Losses

As discussed in Section 3 and identified in the WSDP, the target water losses in the water supply system for the 25 year design period is 15 %. For design purposes this is accepted as the total water losses for Klawer.

Design Flow

The design flow and associated peak flows are calculated as follows:

Average Annual Daily Demand (AADD) = Unit demand x Population

Peak Month Factor (PFm) = 1.46 (based on measured values)

Peak Month Demand (PMD) = AADD x PFm = AADD x 1.46

Peak Day Factor (PFd) = 1.25 (Assumed value)

Peak Day Demand (PDD) = PMD x PFd = PMD x 1.25

Peak Hour Factor (PFh) = 4.0 (Figure 9.11 : Guidelines for Human Settlement Planning and Design)

Peak Hour Demand (PHD) = PDD x PFh = PDD x 4.0

Raw Water Storage

Raw water storage capacity should allow for the two (2) week off period where the flow in the canal system is discontinued. Therefore raw water storage should be fourteen (14) days x AADD during the winter season.

Rising Mains

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 2 - Feasibility & Prelim Design\26202v01rev01.Docm MJ (semir) Page 16 262020KD0 : 26202KD0 Rev A : 2012-06-07

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

Rising mains are designed to supply at least the PDD at 20 pump hours per day for a 25 year design period.

Gravity Mains

Gravity mains are designed to supply the PHD for a 25 year design period.

Water Treatment

Water treatment works are designed to accommodate at least the PDD at 24 operating hours per day for a 10 year design period.

Flow Velocities

Velocities in the bulk water supply pipelines will be between 0.7 m/s and 1.8 m/s with 1.5 m/s accepted as the norm for purposes of sizing of the pipelines.

Pipe Material for New Pipelines uPVC (SANS 966 or ISO 4422), minimum Class 9 pressure rating.

Pipe Friction Factors

The Hazen Williams formulae are used for design with “C” value for uPVC accepted as 140 and 120 for AC.

Pipe Alignment

To avoid air pockets in pipelines, the slope should be greater than 0.3% (0.3 m per 100 m length).

Pipe Trench Excavations

The minimum trench depths are as follows:

• Generally: pipe diameter + bedding + 0.90 m.

• Under cultivated land: pipe diameter + bedding + 1.0 m

• Road/railway crossings: pipe diameter + bedding + 1.2 m.

P:\Waterdept\Klawer\262020 Kd0 - Rbig\G Data\Rbig Reports Work Files\Phase 2 - Feasibility & Prelim Design\26202v01rev01.Docm MJ (semir) Page 17 262020KD0 : 26202KD0 Rev A : 2012-06-07

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

Bedding thickness will be a minimum of 0.10 m or one-sixth of the pipe diameter, whichever is greater.

Pump Stations

All phased pump stations are designed to supply at least the PDD at a pumping period of 20 hours/day for an initial phase design period of 15 years.

Reservoir Storage Capacities

All phased storage reservoirs must have a capacity of at least 24 hours of PDD for an initial phase design period of 15 years.

9. PROPOSED BULK WATER INFRASTRUCTURE

Based on the shortfall in bulk water infrastructure components identified in Section 6 the proposed bulk water infrastructure components are outlined below. Please refer to Appendix D for layouts of the proposed bulk water infrastructure.

Water Treatment Works Pump Station

As determined in section 6, the pump station has sufficient capacity for a 15 year design period. However, from visual inspections, it is proposed to refurbish the pump sets to restore the pump station to a good operation condition.

Raw Water Storage

Additional raw water storage capacity of 18 Mℓ needs to be provided. Due to space limitations on the existing WTW site, only another 2 Mℓ raw water dam is possible on the existing WTW site. To alleviate the pressure on the shortage in raw water storage, it is proposed to construct a 2.0 Mℓ treated water reservoir adjacent to the existing 1.5 Mℓ low lying reservoir. It is proposed to implement the 2.0 Mℓ treated water reservoir as Phase 1 and the 2.0 Mℓ raw water storage dam as Phase 2.

It is recommended to conduct further investigations into the possibility to construct another 14 Mℓ raw water storage dam on adjacent property for Phase 3.

MATZIKAMA MUNICIPALITY TECHNICAL INVESTIGATION REPORT RBIG REPORT PHASE 2: KLAWER BULK WATER INFRASTRUCTURE

Water Treatment

Please refer to the recommendations in the Technical Report for the Klawer Water Treatment Plant included in Appendix E, that needs to be implemented.

Reservoir Pump Station

The existing pump station capacity is sufficient for a 15 year deisgn period. However, from visual inspections, it is proposed to refurbish the pump station to a good operating condition.

Rising Mains

The existing rising main capacities are sufficient and no upgrades are required as part of this project.

Reservoir Capacity

The calculations in section 6 indicate a shortage in reservoir capacity of only 22 kℓ with respect to 24 hours of PDD for a 15 year design period. The existing reservoir capacity is regarded as sufficient for the time being and should be re-evaluated at a future stage.

Gravity Main

As mentioned in section 6 the existing two ∅ 160 mm gravity mains are sufficient for the next 5 to 10 years. It is recommended that new zone valves should be installed to create two separate zones, namely Klawer Areas 1 and 2 Low Water Zone (supplied by existing 530 kℓ reservoir) and Klawer Areas 1 and 2 High Water Zone (supplied by the high lying 1.5 Mℓ reservoir). It is recommended to conduct a network analysis at a later stage to determine any gravity main upgrades which will be dependent on water zone boundaries.

10. PROJECT IMPLEMENTATION PLAN

The funds required for implementation of the proposed bulk water infrastructure project will be sourced from RBIG Funding and funds arranged by the Matzikama Municipality. RBIG Funding can only be utilised for the social component. The balance of the implementation funding required will be arranged by the Municipality.

11. PRELIMINARY O&M AND ASSET MANAGEMENT PLANS

Currently the Matzikama Municipality Technical Services Department is responsible for operation and maintenance of all water services infrastructure. The Municipality is aware of the fact that, as with most municipalities, there is a shortage of labour and appropriate skill levels. The Municipality, however, remains committed to implement its Work Place Skills Plan to provide training to ensure that the required skills are developed and maintained.

The Matzikama Municipality has an Operation and Maintenance Plan in place, which will be implemented in the operation and maintenance of the new proposed bulk water infrastructure.

The Municipality also drafted its first Water Safety Plans for Klawer during June 2010. The Water Safety Plans include the following three components:

• System assessment, which determines whether the drinking water supply chain (up to the point of consumption) as a whole can deliver water of quality which meets national standards.

• Identification of control measures in the drinking water systems that will collectively control indentified risks and ensure that health based targets are met. Appropriate means of operational monitoring, will defined for each control measure identified, that will ensure that any deviation from the required performance is rapidly defected in a timely manner.

• Management plans describing actions taken during normal operation or incident conditions and documenting the system, assessment (including upgrade and improvement), monitoring and communication plans and supporting programmes.

MATZIKAMA MUNICIPALITY TECHNICAL REPORT FOR THE KLAWER WATER TREATMENT PLANT

SECTION 1: BACKGROUND

This technical report is based on the annual Process Audit, compiled for Blue Drop and advises on upgrade requirements and technical interventions for Klawer Treatment Works.

The scope of this Technical Report for Klawer WTWs is:

• To assess treatment plant performance and unit treatment processes.

• To compare design capacity with current and future flows and loadings.

• To investigate shortcomings.

• To identify and recommend an appropriate intervention.

SECTION 2: ASSESSMENT OF KLAWER WATER TREATMENT PLANT PERFORMANCE AND UNIT TREATMENT PROCESSES

2.1 DESCRIPTION OF WATER TREATMENT WORKS (WTW)

A schematic layout of the Klawer WTW is shown in Figure 1. Raw water is pumped to a lined raw water dam on the premises of the WTW. From the raw water dam the water is pumped to four slow sand filters.

Filtered water gravitates to a clear water pump, where gas chlorination is applied. Treated water is pumped to a service reservoir from where it is distributed to consumers.

MATZIKAMA MUNICIPALITY TECHNICAL REPORT FOR THE KLAWER WATER TREATMENT PLANT

Table 1 show that all parameters, except for turbidity fall within the prescribed limits of SANS 241.

Using STASOFT computer software, it was calculated that the Calcium Carbonate Precipitation

Potential (CaCO3PP) of the raw water is negative, which indicates that the water is corrosive and needs to be stabilised. Calculations indicate approximately 18 mg/l slaked lime of 95% purity will be required to adjust the CaCO3 PP to the required level of between 2 and 5 mg/l.

2.3 TREATED WATER QUALITY (Abstract from Process Audit Report)

2.3.1 Physical/Chemical quality

Table 2 compares the treated water quality from the Klawer WTW with the requirements of SANS 241-2011 for the period January 2011 to June 2011. Average values were calculated from 12 samples analysed by SANAS accredited AL Abbott Laboratories.

MATZIKAMA MUNICIPALITY TECHNICAL REPORT FOR THE KLAWER WATER TREATMENT PLANT

Using STASOFT computer software it was calculated that the calcium Carbonate Precipitation

Potential (CaCO3 PP) of the treated water is negative, which indicates that the water remains corrosive and will harm concrete and asbestos cement pipes as well as iron and copper utensils in the distribution system.

Calculations indicate that approximately 6 mg/l slaked lime of 95% purity will be required to adjust the

CaCO3 PP to the required level of between 2 and 5 mg/l.

2.3.2 Bacteriological Quality

Laboratory results as tested by the National Health Laboratory Service in Green Point for Klawer are included in Table 2. From a total of 24 samples tested, 73.3% complied with the required standard regarding Total Coliform Count and 100% complied with the required standard regarding Eschericia Coli Type 1.

2.3.3 Critical Evaluation of Unit Processes and Operations

The only unit operation practised at the Klawer WTW is slow sand filtration, while the only unit process applied is disinfection.

Slow sand filtration is considered as appropriate technology to apply when the raw water has a low turbidity such as being the situation at Klawer. It is apparent from the results reflected in Table 2 that turbidity is lowered to an acceptable level during filtration. A compliance of 66.7% was achieved for the 24 samples tested over six months.

SECTION 3: COMPARISON OF DESIGN CAPACITY WITH CURRENT AND FUTURE FLOWS AND LOADINGS

Calculations of available capacity of 4 slow sand filters, each with a surface area of 120 m² operating at a filtration rate between 0,1 m³/m².h and 0,3 m³/m².h show that each filter can handle a flow rate between 12,0 m³/h and 36,0 m³/h.

Taking into consideration that 25 % of the available filters can be out of commission at any time due to cleaning operations, the capacity of the remaining filters over 24 hours will be between 2 592 m³/d and 864 m³/d.

MATZIKAMA MUNICIPALITY TECHNICAL REPORT FOR THE KLAWER WATER TREATMENT PLANT

It can be concluded that the design capacity of the existing slow sand filter system, when operated correctly will be an average between 2 592 m³/d, operating with all filters clean, and 864 m³ when operating properly under semi-clogged conditions, i.e. 1 728 m³/d.

The bulk water supply as metered over 12 months during 2010/2011 indicates that 62 120 m³ was treated at the Klawer WTW. This amounts to an average of 1 699 m³/d which is less than the theoretical capacity of the works, calculated at 1 728 m³/d, but more than the minimum capacity of 864 m³/d when operating under semi-clogged conditions at 0,1 m³/m2.h.

The graph below gives an overview of the flow and design capacity of the Klawer WTW.

MATZIKAMA MUNICIPALITY TECHNICAL REPORT FOR THE KLAWER WATER TREATMENT PLANT

If the filters are operated correctly and cleaning operations occur regularly, so that one of the four filters is offline at any time, the peak day demand (PDD) can be accommodated by three filters at 0.3 m3/m2.h over a 24 hour period, i.e. 2592 kl / d. Therefore, if operated correctly, the capacity of

CONCLUSIONS

MATZIKAMA MUNICIPALITY PROCESS AUDIT REPORT FOR THE KLAWER WATER TREATMENT PLANT

SECTION 1: BACKGROUND AND SCOPE OF THE AUDIT

One of the Blue Drop criteria of the DWA is that the WTWs be subjected for an annual Process Audit. The purpose of the Audit is to advise the Municipality on process optimisation and technical improvements required. These Process Audits needs to be performed at least once a year.

DWA’s minimum requirements for a Process Audit are that it is required to be undertaken annually, the report must include findings and prioritised recommendations and the Municipality must provide evidence of implementation of recommendations.

The scope of this Process audit for Klawer WTWs is:

• To assess treatment plant performance and unit treatment processes.

• To compare design capacity with current flows and loadings.

• To investigate management practices and communication protocols.

• To check implementation of critical control points.

• To determine compliance with Blue Drop System requirements and criteria for the WTWs.

SECTION 2: ASSESSMENT OF KLAWER WATER TREATMENT PLANT PERFORMANCE AND UNIT TREATMENT PROCESSES

2.1 DESCRIPTION OF WATER TREATMENT WORKS (WTW)

A schematic layout of the Klawer WTW is shown in Figure.6. Raw water flows under gravity to a lined raw water dam on the premises of the WTW. From the raw water dam the water is pumped to four slow sand filters.

Filtered water gravitates to a Clearwater pump, where gas chlorination is applied. Treated water is pumped to a service reservoir from where it is distributed to consumers.

Table 1 shows that all parameters, except for turbidity fall within the prescribed limits of SANS 241.

Using STASOFT computer software, it was calculated that the Calcium Carbonate Precipitation

Potential (CaCO3PP) of the raw water is negative, which indicates that the water is corrosive and needs to be stabilised. Calculations indicate approximately 18 mg/l slaked lime of 95% purity will be

required to adjust the CaCO3 PP to the required level of between 2 and 5 mg/l.
