PUB is the national water agency, and manages Singapore's water supply, water catchment and used water in an integrated way. PUB has ensured a diversified and sustainable supply of water for Singapore with the Four National Taps -- local catchment water, imported water, high-grade reclaimed water known as NEWater, and desalinated water. Its approach to water management can be distilled into three key strategies: collect every drop of water, reuse water endlessly, and desalinate more seawater. On April 24, 2017 at the Global Water Summit 2017 in Madrid, Peter Ng, Chief Executive of the Public Utilities Board of Singapore, met with the other members of the Advisory Board to ratify the first six members of the Leading Utilities of the World network, and provide structured feedback on the new members' future plans. The Advisory Board members and the new members of the LUOW were presented with the 'Golden Tap' trophy at the 2017 Global Water Awards to commemorate their membership.
