PUB is the national water agency in Singapore and a statutory board under the Ministry of the Environment and Water Resources. It manages Singapore’s water supply, water catchment and sewerage in an integrated way. PUB is responsible for managing the whole water cycle, from sourcing to the collection, purification and supply of drinking water, to the treatment of used water and its reclamation into NEWater, as well as the drainage of stormwater.

PUB has ensured a diversified and sustainable supply of water for Singapore with a four-tap strategy (local catchment water, imported water, NEWater, desalinated water). To provide water for all, PUB calls on all Singaporeans to play their part to conserve water, keep the water catchments and waterways clean and build a relationship with water so everyone can enjoy the water resources. Singapore can then have enough water for all uses – for industry, for living, for life, now and for generations to come.
