Water Pressure Management Helps Cape Town Save 50m litres

Cape's average collective consumption over the past week was 516 million litres of water per day.

This week’s usage is 5 million litres lower than the previous week’s usage but is still 66 million litres above the required usage target of 450 million for Cape Town. Dam levels have also declined by 0,5% to 21,5% over the past week.

"In supporting the efforts of our residents to lower their water usage, the City of Cape Town’s advanced pressure management programme is yielding results with 50 million litres of water being saved on average per day through the tireless efforts of our Water and Sanitation Department staff. Our first-phase target for this programme was to save 52 million litres per day and we have achieved this ahead of schedule," Neilson said. 

"We are constantly seeing water-saving world-firsts in the making and we must continue our efforts to stretch our water supplies. We have to continue to strive to meet our 50-litre target. Judging from what we have achieved thus far, we can do it.

"We must use only 450 million litres per day to stretch the available water supplies through the rest of the year, come rain or shine."

The City has been expanding its roll-out of pressure testing with the purpose of using the results to implement more automated pressure zones across the metro in an effort to help reduce water usage to 50 litres per person per day. By creating automated pressure zones, which has been ongoing for many years, the City is able to adjust water pressure remotely and work more efficiently as it implements pressure management.

This technology reduces the pressure of the flow of water and thus helps to reduce water usage as well as bursts and leaks. 

Water management devices continue to be installed on the connections of high water users who are in contravention of water restrictions Neilson added, with additional teams working around the clock to detect and repair leaks.
