Commercial operations in Singapore commenced
Black & Veatch has announced that Stage 1 of the Sembcorp Changi NEWater Plant (SCNP) in Singapore has started commercial operations. Black & Veatch provided full design engineering for the plant along with construction support and commissioning services.
“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 metres of NEWater per day.”
Sembcorp Industries, the plant owner, started to supply NEWater to PUB, Singapore’s National Water Agency on 31 July. Stage 1 of the plant supplies Singapore with 69 million litres per day (or 69,000 m3/d) of high-quality recycled water or NEWater 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.
SNCP relies on advanced water treatment process steps, which include micro-filtration membranes, reverse osmosis membranes and ultraviolet disinfection to produce the water.
The design of the SCNP minimises land use and construction costs by placing the main facilities on the roof of the Changi Water Reclamation Plant. Treated used water from the CWRP is pumped directly to the SCNP as feedwater, minimising the extent of pipework for conveyance.
