1. PROJECT INTRODUCTION Definition of Problem WSM Leshika Consulting (Pty) Ltd has been appointed as term consultant to assist the Department Water Affairs to update the Implementation Ready Study for LPR008 Glen Alpine Regional Water Scheme previously done by EVN Consulting.

Due to the water shortage and poor water quality prevailing in the Blouberg and Molemole Local Municipalities it is considered to utilize the Glen Alpine Dam water or a Regional Ground Water Scheme to augment and blend the existing groundwater source.

The study is intended to review and update the findings of the previous IRS study done by EVN Consulting with the latest infrastructure, population and water requirement information. The designs have to be altered if needed to incorporate the new information. The study also needs to try and establish alternative options if available.

The study involves the water supply to 78 villages, located in the Blouberg and Molomole local municipalities, which is currently essentially from groundwater. The groundwater potential varies greatly across the area and although many high yielding boreholes exist, water quality is poor (classes 3&4) and cannot be safely utilized without treatment. The operation, maintenance and management of distant boreholes are generally sub-standard which results in borehole installations being damaged, abandoned and not able to operate. Internal reticulations are basic and rudimentary with street standpipes and sub-standard level of service.

The current water demand situation shows a deficit of 6 806 Kl/day currently when the 1.5 times Summer Peak factor is taken into consideration. That is a total of 2,48 Mm³/a and shows that the amount of water available from the Glen Alpine dam, 2,18 Mm³/a, is not sufficient to service the area up to required service levels.

The level of service taken into consideration was mostly according to RDP standards, but with an overall target as follows: • Basic supply at 35 l/c/d for 80% of the area • Higher supply at 90 l/c/d for 18% of the area • Urban supply at 150l/c/d for 2% of the area

According to the Infrastructure audit done the daily demand is 8 953Kl/day that amounts to 3,27 Mm³/a.

Future level of service is proposed to be house connections with at least enough water to meet the free basic water requirement, but with an overall target as follows: • Basic supply at 45 l/c/d for 70% of the area • Higher supply at 90 l/c/d for 25% of the area • Urban supply at 180l/c/d for 5% of the area A summer peak factor of 1.5 times normal demand was also taken into consideration.

3. WATER CONSERVATION / WATER DEMAND MANAGEMENT The townships water reticulations are poorly maintained and that results in greater water losses. A culture of non-payment also persists in the area. Illegal connections are also found in some areas, as well as illegal connections to adjacent informal dwellings, similar to the illegal supply of electricity. Where payment is collected, a flat rate is often charged given that customer consumption metering is often non-existent.

The sustainability of the services will depend on the ability to maintain the reticulation systems, to minimize household plumbing leakages and to maintain a good assurance of supply so as to justify the payment for those services. Where street standpipes are installed, losses associated with poor control (such as running taps) or illegal connections are widespread.

Most rural areas do not have access to water services, and rural communities rely mostly on water obtained directly from streams or boreholes. The provision of water services to rural areas, however, depends on prevailing local conditions in respect to the possible source of water (surface or ground water), its proximity and the population density. Providing water to within 200 meters of a household, as required by the minimum standard of services, can be a challenge. Reasons include the low population density and the cost of pumping water from sources that are situated much lower than the dwellings to be supplied. In some cases, wastage through poor control of standpipes also occurs. The problem is compounded by the fact that most consumers with limited water consumption cannot afford to pay for the cost of being supplied with water. Targets for cost recovery for the water services authorities or providers in charge of these areas are often not achieved and government intervention, by way of subsidies or administrative support, is often required.

The opportunity for WC/WDM in rural areas will be to contribute to the sustainability of the services once they have been developed. A system of prepaid water meters in the rural areas is proposed to ensure water is used more efficiently manner and to limit wastages.

4. WATER QUALITY Water quality data from GRIP database provide the statistical support to this study (Figure 2.4). In the Blouberg LM, a total of 306 boreholes have meaningful data attached; (52%) are associated with unacceptable water quality ( Class III – Class IV ); 198 boreholes (27%) have marginal water quality ( Class II ) and only 110 boreholes (21%) have acceptable water quality ( Class 0 – Class I ). In Molemole, the database contains 255 sampled boreholes whereby the following generalizations can be made

A total of 80 boreholes (31%) are associated with unacceptable water quality ( Class III –Class IV ); 98 boreholes (39%) have marginal water quality (Class II ) and 77 boreholes (30%) have acceptable water quality ( Class 0–Class I ).

2. Terminal System: Senwabarwana to Mogwadi 2.1 Pump system 15 kW 2.2 Pump main 150 dia x 6,5 km 2.3 Terminal Reservoir 1 800 kl 2.4 Gravity connector main to Mogwadi area : 150 dia x 4 km

6.2 Option 2 Establishment of a Regional Ground Water Scheme The most efficient procedure in using groundwater as water supply option for the Glen Alpine IRS would be to focus mainly on the 6 schemes indicated on Figure 6.2.1 and Figure 6.2.2. The schemes are located on geostatistical- computed boundaries with a green to blue hue and the colours indicate a groundwater potential greater than 100 kl/day. This computations were outputted during a regional groundwater resource assessment protocol conducted in February 2014 under the project name WM14000 Regional Study of Hydrogeological Characteristics at Four Local Municipalities within Capricorn District .

The protocol identified high groundwater potential areas in Blouberg LM area along and between the Klein Tshipise and Tshipise faults. Alluvium along the Mogalakwena River, along the Brak River.

Figure 6.2.2

This groundwater potential has been confirmed from recently pump tested boreholes during the completion of project WM14030 Hydrological Report Pertaining to the Development of Groundwater at Brilliant Village and Ga-Mokwele Village, “Senwabarwana GWS”, and warrant further exploration in other schemes. The designated schemes are Avon GWS, Blouberg RWS, Senwabarwana GWS, Blouberg RWS, Ga-Hlako RWS, and Taaiboschgroet.

It is recommended that a detailed groundwater development program be initiated to test the validity of the study WM14000 and to augment water demand. This can be achieved by utilizing an integrated groundwater exploration approach, viz: hydrocensus, tectonics and geodynamics analysis, stress / strain analysis, field structural mapping, remote sensing and detailed surface geophysical siting techniques. Pump testing of existing boreholes and drilling and testing of new boreholes where potential high yielding aquifers may exist. Conceptualize flow dynamics (interconnectivity), regional directional permeability, transmissivity, flow paths (including dating and tracing of deep water) in the identified water-bearing structural features is envisaged. Determine storage capacity and storage coefficients (and sustainability yield constraints) of the various geological domains and its reliability during droughts using appropriate investigative techniques (scientific test pumping) and water balance models developed by WSM Leshika.

The estimated cost of the project is detailed below.
