Technology to Deliver Clean Water for Industrial and Drinking Water Use in Singapore

Xylem Inc. (USA), a leading global water technology company dedicated to solving the world’s most challenging water issues, has been awarded a contract worth more than $500,000 to supply ultraviolet (UV) disinfection solutions to a major municipal water reclamation facility in Singapore. As a result of the extensive treatment including Xylem’s Wedeco UV disinfection solution, the city’s industrial sector and communities living in the east of the city, will benefit from an additional 228,000 tons (50 million gallons) of reclaimed water per day.

The second Changi Water Reclamation Plant will include microfiltration, reverse osmosis and Xylem’s Wedeco Spektron 2000e UV disinfection system and is an initiative of the Singapore Water Reclamation Study, also known as the NEWater Study. NEWater is high-grade reclaimed water produced from treated used water that is further purified using advanced membrane technologies and ultra-violet disinfection, making it ultra-clean and safe to drink. Currently up to 30 percent of Singapore’s water needs are met by reused water. NEWater is working to meet 55 percent of Singapore’s water demand with reclaimed water by 2060.

Johnson Tang, Managing Director, UESH Holdings Pte Ltd, the company responsible for constructing the new facility, said, “This second Changi water reclamation plant is another important step toward Singapore securing the majority of its water needs from reused water. Xylem’s Wedeco Spektron 2000e UV system delivered on the project requirements for a sustainable and efficient wastewater disinfection option with a low life cycle cost.”

Robin Wong, General Manager, Xylem Singapore and Regional Marketing Director, Greater Asia for Xylem said, “Singapore is at the cutting edge of water reuse. As a company focused on developing innovative, efficient solutions to the global water challenges, we are proud to support this latest step in the nation’s journey towards increased water reuse.”

Xylem’s Wedeco Spektron 2000e UV disinfection systems feature low-pressure, high-power 600 watt Ecoray UV lamp technology, reducing lamp count by 60 percent, minimising maintenance and lowering energy costs. The systems are designed for maximum effectiveness against waterborne pathogens and have been extensively tested, meeting the requirements of recognised regulations for safe and sustainable water disinfection, including the German DVGW directives, the US EPA’s UVDGM and the NWRI Guidelines for Drinking Water and Water Reuse (2012).

The second Changi Water Reclamation Plant will be operational in 2016.
