Previous to the pressure management of Goodwood the areas experienced pressures in excess of 9 bars and were not discrete zones. A comprehensive feasibility study was undertaken prior to the tender. The water supply system experienced high levels of leakage due to high pressures, frequent burst pipes and aging water infrastructure. In this regard, the City of Cape Town requested tenders for the design, construction and commissioning of a sustainable pressure management solution for Goodwood.

The pressure management solution involved the construction pressure management installations on the three feeds to Goodwood. All other supplies to these areas were shut in the course of the project. (now Divisional Valves or DVs).
