Expect water interruptions next week, but don't panic: Metro says

MAY 13, 2015

The Nelson Mandela Bay Municipality has warned that residents in outlying suburbs may experience water interruptions from Monday as technicians repair a Main Water supply pipeline.

"Two main Elandsjagt/Churchill supply pipelines cross the Maitlands River at the Maitlands River Pipe Bridge. The larger pipe is a Socomon 1125mm Diameter pipe and the smaller pipe is a 675mm Diameter Steel pipeline.

"The Socomon pipe experienced a failure of a joint seal and this caused a visible leak on the upstream side of the pipe bridge. The Soccoman pipe will be isolated for repairs but the steel pipeline will still be functional during repairs," expleined Nelson Mandela Bay Municipality Director of Communications, Rolland Williams.

"The repairs to this pipe joint could not be carried our immediately until the controls at a pumpstation located on the pipelines was repaired first. This was completed last week and now the joint repairs can be planned."

He said that the programme was as follows:

  • Monday 18 May 2015: Isolate the 1125 mm dia Soccoman pipe and drain the pipe via scour valves.
  • Tuesday 19 May 2015: When the pipe is empty inspect the seal.

                                Contractor to clean, prepare and install seal (+ -8 hours).

                                Start to refill the pipe and, when full, open the isolating valves.

  • Wednesday 20 May 2015: System will start to be filling and it will take about 48 hours for the whole system to be filled before it will return to normal.

"The Churchill pipeline system supplies 30% of the water to Nelson Mandela Bay. As a result of these repairs, supply to the Bay will not be affected if we all use water sparingly during this period.

"However, Blue Horizon Bay, Seaview and Kini Bay may experience temporary interruptions in supply over the period of the repair programme, that is Monday to Friday next week," Roland said.

"Residents are assured that they NEED NOT PANIC, AS THERE IS SUFFICIENT SUPPLY IF WE ALL USE WATER SPARINGLY OVER THIS PERIOD."
