Investigations are ongoing; works start this week to replace 170m of pipeline in St 21 area

National water agency PUB is checking all 100km of water pipes in Bukit Batok after initial observations found that corrosion caused two water pipes in the estate to burst in the span of less than a week.
Investigations into the incidents are ongoing, including what caused the pipes to corrode, added PUB yesterday, even as it looks to speed up a project to renew old water pipes islandwide.
On Sept 26, and then on Sunday, pipes had burst in Bukit Batok West and Bukit Batok East, respectively. Water spouts rose several storeys and caused localised flooding.
Mr Michael Toh, director of PUB's Water Supply (Network) Department, told reporters during a site visit to Bukit Batok that both pipes were laid in the 1980s, when Bukit Batok New Town was being developed.
The pipe that burst in Bukit Batok West was a 700mm-diameter high-pressure steel pipe and supplied water to the whole Bukit Batok estate.
The one in Bukit Batok East was a smaller 150mm ductile iron distribution pipe.
Starting later this week, PUB will replace 170m of pipeline within the Bukit Batok Street 21 area, which includes Blocks 222 and 223, where the most recent incident occurred. The works are expected to be completed by the end of the year.
PUB will also examine the condition of the old pipes that will be dug out in Street 21 before deciding whether to step up the frequency of inspections elsewhere in the estate.
