The Development Bureau said on Sunday the plant at Shek Wu Hui in the New Territories, which processes already treated sewage to produce water for non-drinking uses, could help conserve the equivalent of nearly 9,000 swimming pools of fresh water.
The bureau said the plant had been providing recycled water for flushing at three schools in Sheung Shui and four housing estates since March, with the rest of North district still using fresh water.
“In full swing, it can save about 22 million [164.6 million liquid gallons] cubic metres of fresh water consumption per year, which is equivalent to the capacity of 8,800 standard swimming pools,” the bureau wrote on its blog.
The plant will extend its coverage to other areas in North district in stages.
