There are many hills in Hong Kong. With the amount of pressure required to move water through this complex system, leakage can occur, and the city’s Water Supplies Department (WSD) is taking proactive steps to prevent water loss (the volume of water that passes through the water treatment works minus all authorized consumption and use.
The WSD is implementing various measures including the replacement and repair of aging mains coupled with active leakage control. Since 2005, Black & Veatch has been working with the WSD on continuous monitoring and pressure management assignments for 15 of the 17 major supply zones.
“In one major supply zone in Kowloon Central Region – with schemes successfully implemented since 2009 – the amount of water Black & Veatch is helping WSD save by pressure management is 80 cubic metres of water per hour. That is the equivalent of 2 million litres of water per day,” said Stephanus Shou, Client Director, Black & Veatch.
