Concept
NEWater
Summary
NEWater is the brand name given to highly treated reclaimed wastewater produced by Singapore's Public Utilities Board. NEWater is produced by further purifying conventionally treated wastewater through microfiltration, reverse osmosis and ultraviolet irradiation. The water is potable quality and can be added to drinking water supply reservoirs where it is withdrawn and treated again in conventional water treatment plants before being distributed to consumers. However, most NEWater is currently used for non-drinking purposes, mostly by industries with production requirements for high purity water.
Singapore considered water recycling to augment its limited fresh water supply starting in the 1970s. A Master Plan drafted in 1972 identified water reclamation and desalination as alternatives to reduce dependence on imported water from Malaysia. Subsequently, an experimental water reclamation treatment plant was built in 1974, but the operation was terminated after only one year due to costs and reliability issues.
In 1998, the Public Utilities Board (PUB) and the Ministry of the Environment and Water Resources (MEWR) initiated the Singapore Water Reclamation Study (NEWater Study). The aim was to determine if NEWater was a viable source of raw water for Singapore's needs. NEWater and desalination both were explored to reduce reliance on water imported from Malaysia, which has long been a source of friction between the Malaysian and Singapore governments. The Malaysian government is treaty-bound to sell water to Singapore until 2061, but it has no obligation to do so after that date.
In 2001, PUB initiated efforts to identify non-potable uses of water. NEWater, because of its high quality, became the supply of choice for industries' demands. This use provided an outlet for this new water supply without increasing the demand on the limited potable water supply.
The PUB launched NEWater to the public in 2003, with the opening of the first two NEWater plants - the Bedok and Kranji plants - as well as the NEWater Visitor Centre.
