Broken Sewage Pumping Mains in Stanley (9/12/1999)

The Drainage Services Department has completed the emergency repair to two 350-millimetre diameter pumping mains this (Thursday) evening after they were broken by a contractor working on a slope in Wong Ma Kok Road yesterday.

A spokesman for the department said that discharge to the sea had stopped and pumping of sewage from the Stanley Main Pumping Station to the Stanley Sewage Treatment Works for treatment had resumed at around 5 pm today.

"Five tanker trucks have been employed to transport sewage from the Stanley Main Pumping Station to the Stanley Sewage Treatment Works for treatment before final disposal since yesterday. "About 225 cubic metres of preliminary-treated sewage has to be discharged to the sea from the emergency outfall of the pumping station between 11:30 a.m. to the early afternoon because of the high flow during peak hours," the spokesman said.

"We are still liaising with the Civil Engineering Department (CED), the employer of the contractor, to ascertain the cause of the incident," he added.

Meanwhile, a spokesman for the CED confirmed that at the time of the incident, the contractor was carrying out drilling works for the installation of temporary soil nails for excavation works.

The works are part of the upgrading works for the slope adjoining Wong Ma Kok Road under the Landslip Preventive Programme of the department.
