Aim
Toensure the sustainability of our water supply - our ultimate aim is to be self- sufficient - and to manage water pollution.

Actions and Accomplishments
In order to ensure a suitabke supply of clean water, regular clean-up efforts are made to keep our water sources and waterways clean. The government has also pursued a programme of conserving our existing resources, maximising our water catchment areas and diversifing our water sources.

- The clean-up of the Singapore River and the Kallang Basin cost S$200 million and took 10years to complete. Today, the rivers are popular with tourists and loals for water sports and water spots competitions. The clean water has also enabled fish and prawns to return to the rivers.

- Water catchment areas are out-of-bounds for industries that may produce toxic chemical by-products.

- Industrial wastes are required to be treated before being discharged into the sewerage system.

- The Deep Tunnel Sewerage System (DTSS), when fully operational in 2008, will carry sewage from all existing sewers to two centralised water reclamation plants in Changi and Tuas, where it will be treated.

These measures ensure that the waters in our seas, rivers and reservoirs are all clean. Work has already begun to expand our catchment areas to two-thirds of the island, and that the successful operation of the desalination and NEWater plants has helped us to deversity our sources of water.
