The sewerage network collects used water from domestic and non-domestic (e.g. industrial, commercial, etc) sources.
Used water is channelled through a combination of gravity sewers and pumping stations to the water reclamation plants, where it is treated in accordance to international standards. Part of this treated used water, which is safe enough to be returned to nature, is sent to a separate treatment system in the NEWater Plants. The remaining is sent back to the sea.
