SINGAPORE - United Engineers, through a 20:80 consortium between its wholly-owned environmental engineering subsidiary UE NEWater and BEWG International respectively, has been selected as the preferred bidder to design, build, own and operate the second NEWater plant at Changi.

The project will have a daily production capacity of 228,000 cube metres and is expected to be completed in late 2016.

The plant will purify treated used water from Changi Water Reclamation Plant and turn it into ultra-clean, high-grade reclaimed water known as NEWater.

The second NEWater plant at Changi will be constructed on the rooftop of the existing Changi Water Reclamation Plant, and the main processes that will be adopted are microfiltration and reverse osmosis followed by ultraviolet disinfection.

BEWG International is a wholly-owned subsidiary of Beijing Enterprises Water Group, which is listed on the main board of Hong Kong Stock Exchange and is the flagship vehicle of Beijing Enterprises Holding, a Beijing governmental state-controlled enterprise.

United Engineers shares soared 3.6 per cent to $2.87.

The price spike drew a query from the Singapore Exchange around noon time.

But as at 10pm, the company has yet to respond.
