Overview

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

About Us

Water for All: Conserve, Value, Enjoy

PUB has ensured a diversified and sustainable supply of water for Singapore with the Four National Taps (Water from Local Catchment, Imported Water, NEWater, Desalinated water).

To provide water for all, PUB calls on all to play our part to conserve water, keep our water catchments and waterways clean, and build a relationship with water so we can enjoy our water resources. If we all play our part, we can have enough water for all our needs – for industry, for living, for life.

Mission

To ensure an efficient, adequate & sustainable supply of water.

Vision

Water for All: Conserve, Value, Enjoy.

Singapore’s National Water Agency

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.

PUB built the Deep Tunnel Sewerage System (DTSS) for long-term sustainability. An integral part of the water loop, the DTSS is a super highway that channels used water to a centralised water reclamation plant for treatment. The treated used water will then be discharged into the sea or further purified into NEWater.
