PUB trials rover to pump out floodwater in inaccessible spaces ahead of year-end rainy season

In short

The remotely operated vehicle can run for at least seven hours and drain up to 500 cubic meters of water per hour from depths reaching 70 centimeters. It is being tested under a one-year lease ahead of the monsoon period spanning November to January. The rover also supports drainage in coastal areas when high tides force tide gates shut during downpours. In tandem, the agency is expanding its detection network by installing 30 new road kerb sensors across flood-prone areas.

SINGAPORE - The next time an underground carpark or a mall basement floods in Singapore, an amphibious yellow rover could come to the rescue.

The new remote-controlled pump vehicle, which is slightly larger than a motorcycle, is one of the new anti-flood measures that national water agency PUB rolled out on Nov 12, at the start of its third annual flood resilience campaign.

During the rainy season, which usually lasts from November to January, flash floods can occur when heavy rain overwhelms Singapore’s drainage system, especially in low-lying areas.

While Singapore has not officially entered this wet phase of the north-east monsoon season, heavy rain in early November had already caused a flash flood at the junction of West Coast Road and West Coast Way on Nov 10.

The campaign highlights the message that flash floods can happen anytime and anywhere, and everyone needs to be flood-ready.

Angela Koh, PUB’s deputy chief executive for flood resilience, said: “Flood resilience is not about being lucky and hoping for the best... it is about being prepared for the unexpected.

“PUB will continue…
