Used Water

The colonial government started the first sewerage scheme in 1910. The system then consisted of only a network of sewers and 3 pumping stations and a trickling filter plant to serve the central area of Singapore.

The sewerage system is designed based on a separate system whereby used water is collected separately in a network of underground sewers that lead to a treatment plant. Stormwater and surface runoff are collected in open drains and channeled to rivers and reservoirs.

An intensive sewerage development programme began in the 1960's to meet the demand of the rapid housing and industrialisation programme.

Today, 100% of our population is served by modern sanitation.
