Every day, litter on land is washed by rain or blown by winds into our drains and canals which lead to our reservoirs – one of our Four National Taps. As a pillar of Singapore’s self-sustainable water supply, keeping our waterways and reservoirs clean is vital to the health of the people and the environment. WWS is a special, independent environmental organisation established in 1998, with a mission to bring people together to love our waters and to inspire stewardship for our environment through education and volunteerism.
