Pressure Management in Municipalities
To tackle the problem, a pressure management system was installed to control the pressure of the incoming bulk water, allowing for a reduction of supplied water to Sebokeng and Evaton during off-peak periods with a consequent reduction in leakage. The project was constructed using labor-based methods and a high level of stakeholder consultation to ensure positive support from the affected communities.
At a capital cost of US$1,350,000, funded by the private sector on the basis of a payment mechanism linked to saved bulk water costs over a 5-year period, the project achieved a 10,000,000m3/year reduction in withdrawals from bulk water sources. It also resulted in an improved status of the municipality enabling to access additional funding for water demand management activities, as well as a catalyst for other water demand interventions.
