Introduction Polokwane Water Supply Provision of water in accordance with the obligations of the municipality as Water Services Authority is a high priority for the municipality. To meet Polokwane Municipality s strategic vision, an Integrated Water Master Plan was developed in phases, with an aim toultimately address the full water distribution cycle i.e. from Source-to-Tap-to-Effluent discharge for all areas, and all water supply infrastructure within Polokwane Municipality. The supply areas consist of the City and urban areas as well as an extensive rural area (70%), and both urban and rural areas are facing severe challenges in terms of water services. 3

Polokwane Water Services - Scheme Areas In terms of water services Polokwane Municipal area consist of 15 Water Regional Scheme area which covers both rural and urban areas namely: Aganang RWS Badimong RWS Boyne RWS Chuene Maja RWS Houtriver RWS Laastehoop RWS Moletji East RWS Moletji North RWS Moletji South RWS Mothapo RWS Olifants Sand RWS Sebayeng Dikgale RWS Mankweng RWS Molepo RWS Segwashi RWS 5
Background Polokwane City Water Supply The main water supply sources currently supplying water to Polokwane City (excl Perskebult boreholes) are: Average Supply to Polokwane City (current) 6.9 ML/day 1.2 ML/day 14 ML/day 1 ML/day 21.6 ML/day 26.1 ML/day 69.4 ML/day Resource Name Polokwane Boreholes Pelgrimshoop Boreholes Dap Naude Dam Seshego Dam Ebenezer Dam (LNW)* Olifants Sand WS (LNW)* TOTAL *Currently Ebenezer WS = 19.9 ML/day average and Olifantspoort WS = 24.8ML/day A water supply shortfall in excess of 30 Ml/day was calculated if water losses are included 6
PROPOSED WATER RESOURCE DEVELOPMENT AND AVAILABILITY A summary of the identified water resources indicating the impact vs the timeframes for interventions is as follows: Perskebult Boreholes Pelgrimshoop boreholes Bloodriver Wellfield Seshego Boreholes Sand river South Wellfield Sterkloop Wellfield Polokwane boreholes Sand river North Wellfield Seshego Dam Ebenezer WS Olifantspoort WS Dap Naude WS Other (incl De Hoop Dam infrastructure, Wastewater reclamation, irrigation buyouts, Malmane dolomites, etc) Water Supply in (ML/day) Short Term Medium Term Long Term Water Resource Current Average Peak Average Peak Average Peak 1.8 1.8 1.8 2.2 2.2 2.2 1.7 3.4 1.7 1.5 3.0 1.5 2.8 5.6 2.8 2.9 5.8 2.9 1.2 2.4 1.2 5.8 11.6 5.8 2.0 2.0 2.0 21.6 21.6 21.6 26.1 26.1 26.1 12.6 12.6 12.6 0.0 1.2 0.0 1.4 0.7 2.2 0.0 2.6 1.0 19.9 24.8 12.6 1.8 4.2 3.4 3.0 5.6 5.8 2.4 11.6 2.0 21.6 26.1 16.0 1.8 2.2 1.7 1.5 2.8 2.9 1.2 5.8 2.0 29.6 48.1 17.9 1.8 4.4 3.4 3.0 5.6 5.8 2.4 11.6 2.0 29.6 48.1 20.9 TBC TOTALS 66.4 82.2 98.1 82.2 103.5 117.5 138.6 7
Polokwane Water Supply - Continued For both rural areas and urban areas groundwater development has been found to offer the best option for immediate / short term development - considering the many associated benefits such as: availability, sustainability, proximity (saving billions in bulk infrastructure), much lower cost of infrastructure as well as maintenance and operational cost, no storage dams, and mostly no expensive treatment required, Therefore groundwater development is given the highest possible priority 8
IDENTIFIED SOLUTIONS - Short Term Solutions The following short-term solutions are being addressed: Identification and exploration of all bulk ground water resources within the boundaries of the City have been completed as part of the first phase of the Water Master Plan. The Water Master Plan for Polokwane Municipality is also complete. Condition assessment of the existing ground water systems within the city boundaries in terms of their stage of functioning and their adequacy is complete. A thorough yield analysis of all the existing and newly identified bulk ground water supply resources was done and additional boreholes were drilled where identified. 9
Strategic Projects (Budget) The Municipality explored all possible funding sources for the implementation of its cstlytic projects as follows: Allocation of its own Internal Capital Reserves Loan Funding through DBSA and IIPSA RBIG WISG 14
Funding challenges The impact of Covid-19 on Infrastructure Development Lower collection rate Grants allocation reduction 15
Projects that may fail to start due to grants reduction Polokwane RWWTW Civil, Mechanical and Electrical; Refurbishment of Mankweng WWTW; Refurbishment of Seshego WWTW; Polokwane WWTW Phase 2 refurbishment. 16
