Location and Background Information This document focuses of on the settlement of the Ga-Makogbodi GWS . This is a rural settlement cluster which is located in the north western part of Aganang Local Municipality (ALM). Capricorn District Municipality is the Water Service Authority (WSA) throughout the MLM. The cluster relies entirely on groundwater from the local aquifer to meet the domestic and agricultural needs. The majority of the settlements are rural and rely on agriculture as the main economic activity. The potential to develop agriculture and tourism within the municipality has been identified as a growth direction, but the lack of infrastructure is seen to be the major threat to local economic development. Demographics, water requirements and availability The population of Ga-Makobodi GWS was estimated for 2007 at 29 249 people. This is projected to increase to between 33 665 for a low growth scenario and 37 037 given high growth, by 2030. The level of service within this scheme area is meduim. A large portion of the population (30%) has a level of service, which is below the RDP level, 32% are at RDP level, while the remaining 38% are above this level. This therefore becomes a necessary focus for improvement, and will require more water. Water provided to this area is currently sourced from the local aquifer. Although abstraction volumes are not known, it is calculated that the study are requires a minimum supply of 1.274 Million m 3/a to meet their current (2010) needs. With the expected growth in population and a continued planned improvement in services, this requirement increases to between 1.756 and 1.931 Million m 3/a by the year 2030. The current groundwater infrastructure has the G:\390778_DWAF North\7REPORTS\Strategies\All Strategies_21June2011\Limpopo\Capricorn DM\Aganang LM \Ga-Mokobodi GWS_May2011_V3.docx May 2011 i RECONCILIATION STRATEGY FOR GA-MOKOBODI GWS REPORT NO. { } potential to supply 1.711 Million m 3/a of water to the scheme for domestic use. This is calculated on known equipped boreholes and estimated borehole yields. This potential supply is sufficient for the current needs of the study area, but will be insufficient for future need of the study area and it is anticipated that the scheme will be deficient of water within the next 10 to 15 years. Additional water is potentially available from the local aquifer and this can be used to augment the current domestic water supply, although the sustainable use of this aquifer and current users needs to be confirmed through an in-depth hydrogeological assessment of the area. The groundwater quality in the area is generally of a high quality, Class 0. Currently there is no WTW servicing this area. Strategy/Recommendations • Undertake a detailed investigation to determine actual water usages, sustainability of the local aquifer, as well as availability of future supply. • Should it be confirmed that sufficient water is available, augment the current water supply from the local aquifer. This may require either equipping existing boreholes, or installing new boreholes. It is estimated that an additional 0.230 Million m 3/a will be required for domestic supply from this resource by 2030. • Develop and implement a Water Conservation and Demand Management plan with clear performance targets. This must include limiting the wasteful use of water in order to control water consumption and utilise the available resources to their full potential and also limit wasteful water use. • Implement comprehensive monitoring of the groundwater table and of groundwater use by all users (domestic and agricultural) in the area to ensure sustainable use. • Register existing water use and ensure that planned increases in water use are registered with the DWA.

Some conflicting usage volumes were eencounteredncountered in various reports. The population data is of a low confidence level. Pr iority rating for the development of a detailed reconciliation strategy: The Ga-Makobodi GWS is considered to have a Priority 2 (medium/low ) rating for the development of a detailed reconciliation strategy aass the cluster will have in sufficient water to meet future needs within the next 10 to 15 years.
