NEwater
NEWater is treated used water that has undergone stringent purification and treatment process using advanced dual-membrane (microfiltration and reverse osmosis) and ultraviolet technologies. NEWater could be mixed and blended with reservoir water and then undergo conventional water treatment to produce drinking water (a procedure known as Planned Indirect Potable Use or Planned IPU).

Desalinated Water
Desalination is a treatment process that removes dissolved salts from seawater. Two main processes are used for desalination of seawater, namely distillation and membrane processes. In the distillation process, a variety of methods are used to evaporate seawater, condense the vapour formed and obtain distilled water that is essentially free from salts. In the membrane process such as the reverse osmosis process, pre-treated seawater is pumped at high pressure through a semi-permeable membrane that separates the water from the dissolved salts.

Local Catchment Water
A pervasive network of drains, canals and rivers channels rain water to Singapore’s 15 reservoirs. Marina Reservoir, Singapore’s 15th reservoir and the first reservoir in the city, is formed by building the Marina Barrage across the Marina Channel. The Marina Reservoir will have the largest and most urbanized catchment at 10,000 hectares, or one-sixth of Singapore. Local water catchment area will be increased to two-thirds by 2011 when Marina, Punggol & Serangoon Reservoirs are completed.

Imported Water
Singapore has been importing water from Johor, Malaysia, under two bilateral agreements. This will expire in 2011 and 2061.

Local Catchment Water
This kind of water comes from the reservoir in which we gather rainwater for treatment.

Johor Water
Singapore buys this kind of water comes from Johor (A Malaysia city) which is then cleaned and inspected to then come out from our taps.

NEWater
This kind of water which has gone through many processes and is safe to drink after this.

Desalinated Water
This kind of water comes from the sea and has gone through many purification processes and hence, is called Desalinated Water.

Here's the history of Singapore's water history:
A donation of $13,000 by philanthropist, Mr Tan Kim Seng in 1857 heralded the start of Singapore’s piped water supply. An earth embankment completed in 1867 to impound water created Singapore’s first reservoir. Then known as Thomson Road Reservoir, it was later renamed MacRitchie Reservoir. A second reservoir, Peirce Reservoir was completed by 1910.
In 1920s, work began on Seletar Reservoir. Permission was also granted by the Johor Government to look into a supply of water from Johor.
In 1924, work began on the Gunong Pulai Scheme which comprised Gunong Pulai and Pontian Reservoirs, a pumping station, a treatment works and a pipeline to Singapore.
Plans to develop the water resources of Johor River were interrupted by the outbreak of World War II. Tebrau Waterworks was completed in 1953 and a pipeline was laid to convey the water to Singapore.
In 1975, two major water supply schemes were completed. The first was the Upper Peirce Scheme which entailed the construction of a dam at the upper reaches of the old Peirce Reservoir (which was renamed Lower Peirce Reservoir).
The second was the Kranji/Pandan Scheme which comprised Kranji Reservoir, created by damming the estuary of Kranji River, and Pandan Reservoir, by building a dyke to enclose a mangrove swamp. Another major scheme, the Western Catchments Scheme was completed in 1981. Four rivers - Murai, Poyan, Sarimbun and Tengeh were dammed and converted into reservoirs.
In 1986, the Sungei Seletar or Bedok Water Scheme was completed. The scheme involved the damming of Sungei Seletar to form a reservoir (Lower Seletar Reservoir), creation of Bedok Reservoir from a former sand quarry and construction of Bedok Waterworks. Its unique feature was the construction of nine stormwater collection stations to tap the storm runoffs of the surrounding urbanised catchments. Eight of these collection stations are ponds at Yishun, Tampines, Bedok and Yan Kit new town.In the 1980s, the treatment capacities of Scudai Waterworks and Johor River Waterworks were extended. A pipeline from Johor River Waterworks to Singapore, across the Straits of Johor, was also completed. In 1988, work commenced on the Linggiu Reservoir project in Johor. This project, which involved the construction of a dam across Sungei Linggiu, a tributary of the Johor River, and other saddle embankments and ancillary works was completed in 1993. In conjunction with the Linggiu project, another pipeline was laid to convey water from Johor River Waterworks to Singapore. To enhance the operational efficiency and reliability of the treatment and distribution of water, the waterworks, pumping stations and service reservoirs in Singapore, are remotely monitored and controlled from a System Control Centre.

In the next few posts, we will be discussing on the four national taps. Local catchment water, Imported water(Johor), NEWater and Desalinated water. This four taps ensures that Singaporeans will have sufficient clean water to drink and use.

Welcome to this blog. Our group consists of 5 people. Moses, Shawn, Jonathan, Chong Han and Jeremy. This blog is created to campaign for an alternative source of water for Singapore. Singapore now have a few sources of water which can be summarized into the four taps. Local Catchment, Imported Water, NEWater and Desalinated water. We will proposing other alternative source of water for Singapore in the following post.
