PUB carries out structural repairs of drains, canals and waterways, where necessary, to ensure that they continue to function effectively. Minor works include repairing damaged drains due to wear and tear, damaged railings or drop-inlet-chamber gratings.
Major canals and waterways are routinely dredged to keep them free-flowing. PUB also carries out regular hydrographic surveys to monitor the level of silt in major canals and waterways.
