Rehabilitation of Sewer

Used water from households, industries and commercial premises island-wide is collected and conveyed via an extensive sewerage reticulation system for treatment at water reclamation plants (WRPs).

Over time, these sewers may suffer damage from wear and tear, ground movement, tree root intrusion, etc. When this happens, used water may leak from the sewers and pollute waterways, canals and reservoirs. Such leaks do not affect the quality of drinking water, as reservoir water is always treated using advanced technology before it is sent to consumers. But pollution in waterways and reservoirs poses aesthetic and recreational concerns.

Therefore it is important to ensure the structural integrity of the sewer network. To address this, PUB carries out systematic checks and repairs public and private sewers all over the island.
