PUB takes every flash flood incident seriously and assesses the cause of any flash flood.

Vessel Permits (Marina Barrage)

Under the Public Utilities (Reservoirs and Catchment Areas) Regulations 2006, vessels entering Marina Reservoir and other reservoirs in Singapore must obtain Vessel Permits.

Passenger vessels carrying up to 12 people must be inspected and certified fit for the intended purpose by a marine surveyor approved by the Board before the permit can be issued.

Before entering Marina Reservoir, vessels must fulfil certain requirements and obtain a permit from PUB:

Save Water
Water Closet Replacement Project


PUB has launched a project in the older HDB flats to help households who are currently placed on community assistance schemes replace their existing 9 litres water closets with more water efficient ones. This replacement will be done for free, and is aimed at helping families to save water. 

PUB will also replace existing non-water efficient basin taps/mixers and kitchen taps/mixers at the same time.

Smart Shower Programme


PUB will be installing smart shower devices for some 10,000 new homes under a demonstration project over the next few years to further study and validate the conservation effect of such devices. These devices provide real-time information on water consumption during showers. An earlier small scale study found that a person could save up to 5 L a day or about 3% of their monthly water bill, from the use of such devices.
