Location and Background Information The focus of this document includes the settlements in the Flag Boshielo Water Supply System situated in the Eastern half of Greater Marble Hall Local Municipality. These settlements receive water from the Flag Boshielo Water Supply System. The Flag Boshielo Dam provides about 4 Water Supply Sub-Schemes including the sub schemes in Fetakgomo Local Municipality that also receive their supply from Flag Boshielo Dam through a weir in the Olifants River. Water is transported through a network of pipeline system to different rural villages in the above mentioned Local Municipality. Greater Marble Hall Local Municipality settlements receiving water from Flag Boshielo Regional Water Scheme are listed below: Village Name Mmotwaneng Letebejane Ga -Makgatle Elandskraal Mamphokgo North Mooihoek Ngwalemong A Hinlopen Elandskraal X1 Mamphokgo South Makgatla A Mogalatsana LCH Moganyaka North Makgatla B Phetwane Moganyaka South Mohlalaotwane Mohlotshi Manapsane Madiilo Moomane South Leeufontein Seriteng Ga -Masha Tsimanyane Mabitsi B Motseleope Ga -Mmela Mmotwaneng Frischgewaagd Goru Mabitsi A Manotelwaneng Makhutso Vaalbank Mathukhuthela Selebaneng Moeding Arabie LCH Greenside Puleng B Doornpoort X:\G\Proj 1\Proj\390778_DWAF North\7REPORTS\Strategies\All Strategies_19Dec2011\Limpopo\Greater Sekhukhune DM\Greater Marble Hall LM\Flag Bosielo_MarbleHall.docx June 2010 i RECONCILIATION STRATEGY FOR FLAG BOSHIELO WS REPORT NO. {1} Tompi Seleka Agri Van Der Merwes College Puleng A Kraal Ditholong Ngwalemong B Weltevrede Supply is primarily from Flag Boshielo Dam fed by the Elands and Olifants Rivers. Water supply in Leeufontein is augmented by boreholes and some of the villages are also augmented by boreholes that do not appear to be registered or formalised. The water supply level of service according to the Water Services Providers (Lepelle Northern Water) is mostly at and above RDP standard with the major portion of the supply area receiving water through house and yard connections. Leeufontein is one of the villages that receive house connections water supply with water borne sanitation. A small percentage (<20%) was reported to be receiving below RDP level of water service. Waterborne sanitation is reported to be supplied to a limited number of settlements while the major portion of the study area is served with both ventilated and non ventilated pit latrines. The information obtained from WSNIS 2007 on the other hand indicates that more than 40% of households receive below RDP level of water supply service with >50% of households receiving below RDP level of sanitation. Confidence level of Information available for the study area The confidence level for the information in this area is low as some of information from different sources contradicts. Priority rating for the development of a detailed reconciliation strategy: This cluster is considered to have a Priority 4 (high) rating for the development of a detailed reconciliation strategy. Water allocations must be registered.

Groundwater use was recorded as 0.4 Million m3/a).

The surface water combined with sustainable yield of the production boreholes is insufficient to meet the projected water requirements for the cluster for the year 2030. Groundwater estimated at 4.78 Million m 3/a is available to expand the current and future water supply. (iii) The data confidence in the volumes currently available for supply is low as detail on the pumped volumes was not available at the time of the study. The level of data supporting the groundwater estimate should therefore be improved through the validation and confirmation of existing groundwater use. Strategy/Recommendations Short term (i) Develop the Water Conservation and Demand Management plan, with clear performance targets. (ii) Before introducing measures to encourage water conservation, it is important to have an accurate set of baseline data against which any progress can be measured. The first priority must therefore be to ensure that there is an adequate network of water meters and accurate readings are recorded on a regular basis. This would include a borehole census to validate and revise the current groundwater use estimates is required. (iii) Formalise (including the installation of meters and monitoring) of groundwater abstraction boreholes. (iv) Limit wasteful water use in order to control water consumption and utilise available groundwater to its full potential. Long term (i) Monitoring and development of the Water Conservation and Water Demand Management strategy. (ii) Feasibility study for use of surface water from the Flag Boshielo dam. (iii) Feasibility Study needs to be carried out to identify additional boreholes to augment water supply for the Flag Boshielo settlements.
