Location and Background Information This document focuses on the GSM RWS. The scheme is composed of three clusters, namely; Groothoek RWS cluster, Specon RWS Cluster and Mphahlele RWS Cluster. These clusters combined consists of sixty eight settlements; Mphahlele RWS Cluster; (Matinkane, Mooiplaas, Molapo Matebele, Malemang, Boomplaas, Lebowakgomo, Middelkop, Seleteng, Sampse, Letlhokwaneng, Tswaing, Rapotela, Lesetsi, Mosetamong, Phosiri, Lekurung, Magwaneng, Staanplaas, Mabokotswane, Serobaneng, Hwelesaneng, Hlahla, Naauwpoort, Schildpadnek A, Naauwpoort A, Naauwpoort B, Naauwpoort Ext 1, Patoga, Masite, Shotatale, Mabokotswane), Specon RWS Cluster;(Phaswana, Rooibosbult, Byldrift, Byldrift Ext, Morotse, Malekapane, Kgaphanadi, Motserereng, Seswikaneng, Lenting, Tooseng, Marulaneng, Makurung, Dithabaneng, Maralaleng, Thamagane), Groothoek RWS Cluster; (Rafiri, Ga-Mmamogwasa, Sekgophokgophong, Bolahlakgomo, Matome, Mathibela, Mogoto, Ga-Rakgwatha, Moletlane, Makeng, Makuswaneng, Madisa Di Toro, Madisaleolo, Magatle, Mapatjakeng, Droogte, Ga-Molapo, Ledwaba, Mmakotse, Motantanyana, Hwelereng, Lekhuswaneng, Lebowakgomo Township). The GSM RWS is composed of the main town of Lebowakgomo, Zebedelia citrus estates and a number of rural settlements. The GSM RWS dominates the western section of the Lepelle-Nkumpi Local Municipality (LNLM). The LNLM is one of five local municipalities that together form the Capricorn District Municipality within the Limpopo Province of the Republic of South Africa. LNLM is situated in the southern part of the Capricorn District Municipality. The LNLM is bordered by Polokwane to the north-west, Mopani to the north-east, Waterberg to the East and Sekhukhune to the South.

Confidence Level of Information Available for the Study Area The confidence level for the information in this study area is low due to the low confidence in the population estimates as well as minimal existing records of registered water use. Priority Rating for the Development of a Detailed Reconciliation Strategy The GSM RWS possesses a Priority 2 rating for the development of a detailed reconciliation strategy, as the cluster will be deficit of water within the next five to ten years.

This is insufficient for future demands of the scheme. • The GSM RWS is not currently deficient of water, but is expected to be deficit within the next five to ten years. • Although the groundwater resources are over-exploited, this is because they are poorly managed and there is excessive wastage of water used for irrigation. The major aquifers in the area, following management and a comprehensive reserve determination, should be available for utilisation to augment domestic supply. Strategy/Recommendations Short Term • Undertake a detailed investigation to determine actual availability of surface water from the Olifants River for augmentation and sustainability of future supply. • Undertake a comprehensive reserve determination for the dolomitic and Springbok flats aquifers. Long Term • Limit wasteful water use in order to control water consumption and utilise available water sources, to their full potential. • Monitoring and habitual implementation of the WC/WDM strategy.
