SINGAPORE — To minimise occurrences of flash floods during the upcoming Northeast Monsoon season, the PUB is working with the National Environment Agency to step up on drainage maintenance, and has intensified inspections at some 100 construction worksites around the island to check for obstructions in the drains.

In a statement issued today on the monsoon as well as updates on its drainage projects, the PUB also said it has replaced 6,000 scupper holes and drain inlets – found by the side of roads – at flood prone areas and hotspots with an improved design of Drop Inlet Chambers (DICs). These modified DICs have an additional vertical opening that will enable rainwater to be drained from the roads should the main horizontal gratings be partially blocked.

It has also distributed flood advisories to about 500 residential units and shop-houses in flood-prone areas, along with information on what precautions they could take to protect their belongings.

Meanwhile, the PUB will begin on new drainage improvement projects at 36 locations, adding to its on-going drainage projects at 176 locations around Singapore. These drainage improvement projects are part of its strategy to improve flood protection for Singapore.
