Officials said quality has been improving since residents of Queen’s Hill Estate and Shan Lai Court complained of black particles in tap water on May 30.
Speaking at the Housing Authority’s annual special meeting, Ho said she’s been in contact with the director of housing throughout this time.
She said since there are 13 housing blocks involved, she believed workers had installed finer filtration devices much faster than expected.
“At first, I thought it’d take around a week to install all 22 filtration devices because it involves so much work, with so many materials involved,” Ho said.
“But our colleagues finished the installations in a day or two.
“And we can see the difference right away – the water quality was vastly improved.”
Ho said the filtration devices originally used were only capable of stopping particles measuring around one to 1.5 millimetres in diameter from getting through, but the Housing Department has now, on the advice of Water Supplies Department officials, installed sieves that can stop smaller particles down to 0.1mm in diameter.
She said residents have recently been calling officials asking for water meters to be cleaned and that their requests have been forwarded to the Water Supplies Department.
Officials also visited 32 merchants and non-governmental organisations in Queen’s Hill, she said, and they had observed improved water quality
She stressed officials at all levels are determined to serve the people affected and restore their confidence in water quality.
