Location and Background Information The Namakgale-Lulekani RWS Cluster is situated in the south-eastern part of the Ba- Phalaborwa Local Municipality. The Ba-Phalaborwa Local Municipality (BPLM) is one of six local municipalities that together form the Mopani District Municipality within the Limpopo Province of the Republic of South Africa. Ba-Phalaborwa Local Municipality is situated in the central eastern portion of the Limpopo province within the Mopani District Municipal Area of jurisdiction. The Ba-Phalaborwa municipality is bordered by the Kruger National Park to the east, the Greater Giyani municipality to the north, Tzaneen municipality to the west and Maruleng municipality to the south. Ba-Phalaborwa Municipality covers an area of 300,488 km 2 and has an overall population density of 44 persons/km 2. The towns within the Namakgale-Lulekani RWS Cluster and the nearby town of Phalaborwa constitute the major population concentration in BPLM (Mopani WSDP, 2008). Mining is the main economic activity in this region. This document focuses on the Namakgale-Lulekani RWS Cluster. The Namakgale-Lulekani RWS Cluster includes the settlements of Ben ABC, Mashishimale R1, Mashishimale R2, Mashishimale R3, Makhushane R1, Makhushane R2, Maseke, Namakgale, Humulani, Lulekani A & B and Matiko – Xikaya. The capacity of the Olifants River Barrage Water Works situated within the Namakgale- Lulekani Cluster is 63 Ml/day, which translates to 22.995 million m³/a (WSDP, 2009). 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 actual water consumption.

Strategy/Recommendations Short Term • Review water allocations to other water users and registrations from the Olifants River Barrage Water Works to ensure the sustainable use of this resource. • 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. • Water use should be accurately monitored through a network of water meters which should be recorded on a regular basis. Long Term • Manage and monitor the Water Conservation and Demand Management plan.
