ProposalDescription: 

The proposed upgrading of Olifantspoort Water Supply Scheme including Olifantspoort Water Scheme, Ebenezer Water Scheme, and the refurbishment of the Ebenezer WTW.

Expanded_Motivation: 

The proposed upgrading of Olifantspoort Water Supply Scheme, Phase 1 from Olifantspoort WTW to Krugersburg Reservoirs, and Upgrading of Ebenezer Water Supply Scheme, Phase 1 from Ebenezer Pumpstation to Rustfontein, and Mankweng reservoir off-take, will includes the following components of the water conveyance and storage infrastructure: Olifantspoort Water Scheme: The total pipeline length for Olifantspoort Scheme upgrade is 86km from olifants river (abstraction) to Krugersburg reservoirs. There are components of water conveyance and storage infrastructure along the pipeline route, as outlined below: The upgrading of Olifantspoort weir and raw water abstraction works; Construction of 200 000m2 Olifantspoort off-channel storage dam with 5m embarkment height, Construction of 1500mmø raw water mains ( 350m from Olifantspoort abstraction to off-stream storage dam, and 450m from off-stream storage dam to Olifantspoort WTW); Refurbishment of the Olifantspoort Water Treatment Works (WTW); Upgrading of the existing Olifantspoort WTW by constructing new 60 Mℓ/d module; Refurbishment of Pump Station (PS): PS1, PS2 and PS3; Upgrading of Specon Storage Reservoirs; Constructing a new pump stations at PS1 (Olifantspoort WTW) and PS2 and PS3; Duplicate/dualisation of approximately 28.3km (800mmø) existing main by adding another (1500mmø) rising main from Olifantspoort WTW (PS1) to Specon; Duplicate/dualisation of approximately 23.6km (790mmø) existing main by adding another (1500mmø) main from Specon to PS2, and from PS2 Witkos Reservoir; Duplicate/dualisation of approximately 14.6km (740mmø) existing main by adding another(1200mmø) main from Witkos Reservoir to PS3 and Palmietfontein Reservoir; Construction of new reservoirs at Witkos (30Mℓ) and Palmietfontein (50Mℓ); Construction of approximately 8.5km (1200mmø) pumping main with pumping rate of (1900 ℓ/s) from Palmietfontein Reservoirs to OSA164; Construction of approximately 11km (1200mmø) gravity main with pumping rate of (1900 ℓ/s) from OSA 164 to Krugersburg reservoirs. Ebenezer Water Scheme: The total pipeline length for Ebenezer Scheme upgrade is approximately 13.5km. There are components of water conveyance and storage infrastructure along the pipeline route, as outlined below: The refurbishment of the Ebenezer WTW; Refurbishment and modifications to Ebenezer high-lift pump station; Construction of approximately11km(900mmø) new pumping main with a pumping rate of (1250ℓ/s), corresponding to 89 Mℓ /day from Ebenezer high-lift pump station to Rustfontein reservoirs complex; Extension of approximately 2.5km (600mmø) pumping main (Pipeline B) from Chamber GB73 to the Mankweng reservoir off-take. Both of the proposed pipeline upgrades and refurbishment between Olifantspoort and Ebenezer Schemes’ water conveyance and storage infrastructure merge to supply the Polokwane Municipal Area. This will enable an additional 40Mℓ/day to be supplied to Polokwane City (25Mℓ/day from Olifantspoort and 15Mℓ/day from Ebenezer). The total length of pipeline upgrade for these two schemes is approximately 99.5km.
