Wemmershoek Water Treatment Works (WTW) supplies the Paarl and Wellington regions of the Western Cape, which fall under the Drakenstein Municipality. Wemmershoek supplies the Leliefontein Bulk Reservoir Complex (LBRC), servicing Paarl, via a 19 km gravity pipeline. This gravity pipeline continues for a further 11 km to supply Wellington’s Con-Marine and Newton reservoirs, at a maximum capacity of 19 Mℓ/d. The supply capacity to Wellington is deemed sufficient to meet the summer peak demand of Wellington until the year 2034. However, when the supply from Wemmershoek is interrupted due to planned and unplanned maintenance, the maximum capacity reduces to 11.2 Mℓ/d. This capacity is sufficient to meet Wellington’s winter demand for the foreseeable future, but not its summer demand.
