The Western Aqueduct is the single, largest water infrastructure project undertaken by eThekwini Municipality. Commissioned in 2019, it presently supplies water to Durban from the Midmar Dam and the Spring Grove dams and will meet the needs of the Greater Durban region until 2036. It provides additional capacity of 400 ML of water per day to augment the 900 ML currently consumed daily by the city and is thus of high strategic and socio-economic importance to the Greater Durban region. Its route generally runs along existing municipal roads through the eThekwini region from Umlaas Road, terminating at Ntuzuma, Pinetown, and Tshelimnyama.
