Executive summary Background and purpose The Marydale bulk water supply project has three key drivers, namely: a water shortage which results in water restrictions being put in place at times unpotable ground water supplies with high fluoride and nitrate concentrations which fail to meet SANS 241‐1 standards an increasing demand for water mainly caused by a demand for waterborne sanitation Good groundwater potential was found in three boreholes near to the existing boreholes, which would be the least cost and preferred option. No other options were investigated. Project area and benefiting population The project is entirely located in the jurisdiction of the Siyathemba Local Municipality who is the water services authority (WSA) and the sole water services provider (WSP). The project is to benefit the community of Marydale, one of three settlements in Siyathemba. Marydale has an estimated population of 2 735 and by 2035 it is expected to reach 3 686. Approximately 67.2% of the 673 households in Marydale are indigent and benefit from free basic water of 6 kℓ per month. Businesses in Marydale can be described as ‘run of mill’ types such as basic retailing and services. The number of associated services benefiting include one clinic, one intermediate school, and a community hall. Project motivation and objective The main objective of the proposed water supply scheme is to replace the town’s most unpotable groundwater sources to improve water quality to acceptable norms and to increase the quantity of water. Thus, the project aims to: improve the quality of water supplied to domestic users improve the reliability of the water supply to the town ensure adequate future water supply to the town Main components and extent/scope of works A total of 3 new production boreholes will be equipped as part of this project. They are MRE2, MRE1 and MA3 (also see layout diagram on next page) The 3 borehole is situated within the town boundaries and the bulk pipelines will not cross any other land users. The following infrastructure is proposed: i. Electrification of new borehole position with underground electrical cables and step down transformers ii. Equipping of borehole with the required pumps, valves, meters etc. iii. Construction of new uPVC supply pump lines from the new boreholes to existing pipelines and to a new elevated reservoir. iv. Construction of a new 138m³ elevated tower on a 10m footing and down pipes with valve control to the existing water reticulation network. v. Construct building to house MCC and other electrical infrastructure with1.8m high razor wire fence The diagram below indicates the areas of development: Phases and programme The project can be completed within one year i.e. by the end of the 2016/17 financial year. Environmental authorisations were obtained during September 2015. Application ref. No. NC/BA/48/PIX/SIY/MAR2014. The WULA is currently in review by the local DWS office in Upington. A R114.00 admin fee was paid in February 2016, which was required for, to proceed with the review process. Additional formal applications for the construction of the scheme will be submitted upon conclusion of the preliminary design. Alignment, ownership and O&M responsibility The project is aligned to the IDP. The IRS will be presented at a council meeting to be held on 30 March 2016. The Siyathemba Municipality is the WSA for the area and they will take ownership responsibility for the proposed project infrastructure. In addition, the Municipality will act as the implementing agent for the project since it is the most suitable water services institution identified. Job creation Job creation during the construction period is estimated at approximately 18 jobs and 1 337 person days based on previous MIG projects. No new jobs will be created in the operational phase. Institutional Criteria The proposed institutional framework for this project indicates that the local municipality will act as implementing agent for the project, and will, together with the appointed consulting engineers and the Pixley ka Seme District Municipality, manage the project during project execution phase. The municipality has in the past implement projects of this nature and size. The Niekerkshoop bulk water supply project also funded by the RBIG programme, can be listed as an example of one such project successfully completed by the municipality. The municipality also acted as implementing agent on behalf of the Department of Water and Sanitation for this project and the Department was satisfied with the procurement processes followed as well as the financial management of this project. It is further proposed that Siyathemba Municipality should be the owners of the infrastructure. The municipality will be the only benefitting water services institution and the entire project will be implemented within the jurisdiction area of this municipality. Siyathemba Municipality is also the Water Services Authority and Water Services Provider for this area and no other water services institution such as Water boards, Water User Associations are operational in this area. Although the municipality does experience challenges with regards to technical expertise, there is a total of 16 staff members responsible for the maintenance of civil engineering services to the community of Marydale. Their functions are to maintain water, sewer, roads and storm water infrastructure as well as general maintenance to parks and cemeteries and refuse removal services. The proposed new infrastructure (3 new boreholes, 1 X 138m³ elevated tower and associated pipework) will be integrated with the existing system and will be able to be operated by the same operating personnel currently located in Marydale. Project cost and budget allocation The project is estimated to cost R 8 831 109 including VAT. The social component is 86.3%, and this is to be funded from RBIG. The co‐funding amount will be provided by Siyathemba’s own funds. According to the DoRA of February 2016, the Department of Water and Sanitation allocated R10 million in 2016/17 for the project over the MTREF from RBIG. O&M cost The annual O&M cost of the project is estimated at R 40 500 excluding VAT. This amounts to R3 375 per month or R0.38 per kℓ based on total water demand of 107 631 kℓ/a. The O&M cost of the project is small and can be accommodated within the existing tariff. With regards to affordability, the cost of 6 kℓ water is R81.31 p.m. per household which does not exceed the FBW allocation from the equitable share (R99.75). Water demand management/water conservation A complete WC/WDM review was conducted as part of the Technical Feasibility Study. Please refer to Appendix A. The Siyathemba Municipality is committed to get an approved WC and WDM strategy in place and to provide in their budget for implementation of the strategy. The municipality should target to reduce their total water losses to not more than 15%. Through implementation of a WC/WDM strategy the municipality can lower the water losses from the current 51% to 20% in the next five years and to 15% in the following five years. Infrastructure components are sized considering the target water losses of 15%. It is therefore imperative to implement a WC/WDM strategy to minimize the water losses in order to maximize the design life of the new infrastructure. Progress to date The IRS of the project will be presented to the Northern Cape RBIG Planning Coordinating Committee meeting to be held on 13 May 2016. The DWS CAPEX approval needs to follow. Thereafter, detailed design development and tender document preparation can proceed along with tender procurement. Conclusion A sustainable water supply to Marydale is required to relieve water shortages and improve the quality of the water to potable standards. Without this project, Marydale will be without a sustainable water supply.
