PUB Singapore's National Water Agency

PUB, Singapore’s national water agency under the Ministry of Sustainability and the Environment, manages the nation’s water supply and flood resilience through an integrated approach. It secures sustainable water resources via the Four National Taps—local catchment water, imported water, NEWater, and desalinated water—while also mitigating inland and coastal flood risks. PUB works closely with residents, businesses, and government agencies to promote water conservation and strengthen preparedness against climate impacts. Guided by its mission to supply good water, reclaim used water, tame stormwater, and resist rising seas, PUB advances its vision of “Water for Every One. Everyone for Water.”
