‘Improving Quality of Life and Enhancing Sustainable Economic Development’ Wastewater Infrastructure

‘Improving Quality of Life and Enhancing Sustainable Economic Development’ DARVILL WASTEWATER WORKS DARVILL WASTEWATER WORKS  Originally constructed in 1956  Serves the City of Pietermaritzburg  Owned and operated by Umgeni Water  Designed average dry weather flow of 65 Ml/day  Effluent mix: 90% domestic & 10% industrial  Inflow during last wet season reached 150 Ml/day!  Currently discharging approx. 60 Ml/day treated effluent into the Msunduzi River

‘Improving Quality of Life and Enhancing Sustainable Economic Development’ DARVILL WASTEWATER WORKS DARVILL WASTEWATER WORKS This WWW has a current biological treatment capacity of 65 Mℓ/day. Current average daily inflow (Oct 2007 to Oct 2014) is approximately 81 Mℓ/day which is more than the plant’s capacity. The Darvill WWW serves the Msunduzi Municipality.

‘Improving Quality of Life and Enhancing Sustainable Economic Development’ SUMMARY SUMMARY Large augmentation schemes are necessary to sustain the projected demand over the long term It is primarily the responsibility of DWS and Umgeni Water to implement these schemes Total Municipal Non-Revenue Water in Umgeni Water’s supply area is currently 43% Savings in Non Revenue Water could defer implementation of large augmentation schemes Building large capital schemes are major undertakings that require significant lead times and funds to implement There will be a direct impact on the water tariff to consumers either via the CUC or UW tariff
