Public Utilities Board (PUB) – Singapore’s National Water Agency

PUB is a statutory board under the Ministry of Sustainability and the Environment. It is the national water agency that manages Singapore’s water supply, water catchment and used water in an integrated way.

Mission
Supply Good Water. Reclaim Used Water. Tame Storm Water
Vision
Water for Every One. Everyone for Water

PUB is responsible for the collection, production, distribution and reclamation of water in Singapore.

Collection

Rainwater is collected through rivers, streams, canals and drains, and stored in 17 reservoirs. With the pipelines linking the various reservoirs, the excess water can be pumped from one reservoir to another, thus optimising storage capacity.

Production

Raw water is piped to the waterworks for treatment.

Distribution

After treatment, the water is stored in covered reservoirs before distribution to customers.

Reclamation

Water that has been used by customers is collected through an extensive sewerage system and treated at water reclamation plants. Treated used water is further purified using advanced membrane technology to produce high-grade reclaimed water, known as NEWater.
