The Water Supplies Department also said it would continue to investigate Friday’s reports of impurities in the water supply.
Personnel from the department had tested samples from public pipes supplying water to Queen’s Hill Estate and water tanks in all the blocks, with the results showing that they were safe.
They did not find any impurities or damage on filters installed at the connection points of the government’s mains and the property’s water supply system, authorities added.
“As a precautionary measure, the department has immediately arranged for cleaning of the government’s pipes supplying water to the estate. No abnormalities were found after the inspection,” the department said.
“The department will arrange for buildings that have completed cleaning of the water tanks to have samples be tested, to ensure the safety of drinking water. The department will also sample freshwater supply at the affected residential units to make sure the water runs clear.”
As instructed by the department, the estate’s management company had completed the cleaning works at the water tanks of all seven residential blocks and the shopping centre over the weekend.
“The Water Supplies Department will liaise with the Housing Department to continue the investigation from other directions, including detailed inspections of other parts of the water supply system,” it said.
