Water Level Sensors & CCTVs

The interactive map below shows the locations of water level sensors in canals and drains. You can also view pictures from 48 CCTVs at selected locations.

Currently, PUB has more than 300 water level sensors around Singapore for monitoring of the drainage system. These water level sensors provide data on water levels in the drains and canals, enhancing the monitoring of real-time site conditions during heavy storms and response time.

An SMS alert system on the rising water level is now open to the public for subscription. This will facilitate more timely updates to the public on potential flash floods.

Located in areas like Orchard Road, Central Business District, Bukit Timah, Upper Thomson, Ang Mo Kio, Little India, Commonwealth, etc a network of CCTVs provides up-to-date pictures of the conditions at these locations.

Images from the CCTVs will be updated at an interval of 5 minutes.
