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 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.

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

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.

“We have developed a strong working relationship with Sembcorp as a result of this project,” Eberts continued. “We’re now actively looking at opportunities to work together outside of Singapore. By focusing on delivering the least whole-of-life cycle cost for advanced water treatment plants, we are able to provide Sembcorp and companies like them the best outcome for efficiency and sustainability of operations.”
