Location and background Information The focus of this document includes the settlements of Muvomoni, Duvhuledza, Mpandoni, Ha-Begwa, Lukalo, Matoroni, Tshikopane, Masiwane, Tshaulu B, Tshaulu A, Gonela, Buluni, Manzemba, Khambela, Gaba, Phaswana, Tshifudi A, Tshidzini B, Tshidzini A, Musenga and Vhufumba. These settlements are located in the north eastern part of Thulamela Local Municipality. The nature of the settlements is generally rural. The Vhembe District Municipality is the Water Services Authority (WSA) and Lepelle Northern Water is the Water Services Provider (WSP) for this area. Confidence level of information available for the study area The confidence level for the information in this area is Medium. The confidence level in demographic data is high. Demographics, water requirements and availability The population of Tshifudi Cluster was taken from the 2011 census (Statistics South Africa) as 28 334 people. This is projected to increase by 2035 to between 30 736 for a low growth scenario and 33 391 for a high growth scenario. The level of service within this scheme area is as follows: 24% of the population has a level of service that is below the RDP level, 65% are at RDP level, while the remaining 11% are above this level. The prevalence of low service level becomes a necessary focus for improvement, which will require more water. The 2011 urban/domestic water use for the Tshifudi Cluster is given (based on actual bulk water figures) at 1.125 million m3/a (3.082 Ml/day) and with a current population of 28 334 people, this means that the current per capita unit consumption of water is 109 ℓ/c/d, which is lower than the recommended range of the water use best practices for residential consumption per capita (i.e. 250 ℓ/c/d for the high developed areas and 150 ℓ/c/d for the low income areas and informal settlements), but high when considering the level of service of the area (24% below RDP Level). The current consumption will increase along with the population, and level of service upgrades, under a high growth scenario from 1.125 million m3/a (3.082 Ml/day, 109 l/c/d) to 1.579 million m3/annum (4.325 Ml/day, 129 l/c/d) in 2035. The projected water balance for the Tshifudi Cluster for both Urban/Domestic water use is illustrated in Figure 1 below.

Water from the Xikundu Weir on the Luvuvhu River is treated at the Xikundu water treatment works. Water from the Xikundu WTW is augmented with groundwater. The domestic water supply will not require augmentation in the near future, but WCWDM is required in order to ensure sufficient water supply until 2035. The strategy recommendations are presented below. Conclusions and Recommendations The current urban/domestic water requirements of the Tshifudi Cluster is equal to 1.125 million m3/a, supplied from the Xikundu Weir and groundwater. The total volume required by this cluster will increase to 1.579 million m3/a in 2035 according to the high growth scenario. According to the Luvuvhu Government Water Scheme: Water Resources Review that was conducted in 2010 the total water committed to the Xikundu Weir, since the implementation of Nandoni dam has increased to 5.58 million m3/a of which 1.610 million m3/a is shared 20 per cent to Lambani cluster (0.322 million m3/a) and 80 per cent to the Tshifudi cluster (1.288 million m3/a). Groundwater currently utilised in the cluster amounts to 0.27 million m3/a. Water Conservation and Water Demand Management (WC/WDM) measures are required in order to ensure that the current water sources does not need augmentation until at least 2035. These include: o Management Information; VHEMBE DISTRICT MUNICIPALITY March 2014 iii RECONCILIATION STRATEGY FOR TSHIFUDI CLUSTER REPORT NO. {46} o Leakage reduction and o Consumer use reduction. The current operating capacity of the Xikundu WTW of 4.855 million m3/a seems adequate to supply in the total domestic allocation from the Xikundu weir of 3.24 million m3/a presently (2011). An assessment of the infrastructure capabilities to deliver the total committed volume of water to the Tshifudi area needs to be conducted and potential upgrades need to be investigated and implemented if required. The groundwater investigations confirmed that noticeable groundwater resources could potentially be developed (exploitation potential of 0.448 million m3/a) and an economic investigation of developing groundwater resources equivalent to the required infrastructure upgrades should be conducted to determine the most economically viable option. The feasibility of fully developing the available groundwater resources to make additional water available in Nandoni Dam should be considered and investigated in the future, when the water requirements exceed the available yield of Nandoni Dam.
