Sembcorp's NEWater Plant Sends Water to Singapore

Stage 1 of the Sembcorp Changi NEWater Plant (SCNP) in Singapore has started commercial operations, according to an Aug. 26 press release from Black & Veatch, the engineering designer for the facility.

“NEWater is a sustainable water resource for the people of Singapore,” said Ralph Eberts, senior managing director of Black & Veatch’s Asia Pacific water business. “When Stage 2 is completed next year, SNCP will become one of the largest recycled water plants in the world, capable of producing a total of 228,000 cubic meters (50 million imperial gallons) of NEWater per day.”

Sembcorp Industries, the plant owner, started to supply NEWater to PUB, Singapore’s National Water Agency on July 31. Stage 1 of the plant supplies Singapore with 69 million liters per day (or 69,000 m3/d) of NEWater or high-quality recycled water as it is branded in Singapore. Sembcorp was awarded the project in January 2008 and has an agreement to supply PUB with NEWater for the next 25 years.

Sembcorp Industries is a leading utilities and marine group, which provides centralized utilities, energy and water to industrial and other customers in Singapore, the United Kingdom, Asia and the Middle East.

SNCP relies on advanced water treatment process steps, which include micro-filtration membranes, reverse osmosis membranes and ultraviolet disinfection.

The design of the SCNP minimizes land use and construction costs by placing the main NEWater facilities on the roof of the Changi Water Reclamation Plant. Treated used water from the CWRP is pumped directly to the SCNP as feedwater, minimizing the extent of pipework for conveyance.

Quick facts:

  • The Sembcorp Changi NEWater Plant is Singapore’s fifth and largest NEWater plant.
  • Together, the five NEWater plants will satisfy 30 percent of Singapore’s current water needs by 2010.
  • Total area of the plant is 12,300 m2.
  • NEWater storage tanks are sited on reclaimed land, which required greater bored piling depth due to the presence of marine clay.
  • SNCP receives treated used water from PUB’s Changi Water Reclamation Plant, which is designed to collect about half of Singapore’s total used water.
