New 45 Ml post tensioned reinforced concrete reservoir
45ML Storage Reservoir
The initial reservoir at Olifantskop was constructed as a 10Mℓ facility. The Olifantskop reservoirs will act as the balancing facility for the NCLLS as well as the storage facility for the Coega IDZ. In the medium term this site requiring a total storage of some 90Mℓ.
The interim balancing capacity must therefore be upgraded by the addition of a 45Mℓ reservoir in order to supply Coega IDZ at reduced risk and to improve the transfer operations of the low level scheme.
The new reservoir is positioned within the connector pipelines and valve chambers already installed under Phase 1 of the NCLLS.
