Changi Water Reclamation Plant to be expanded

Channel NewsAsia 23 Jun 16;

SINGAPORE: A tender to expand Changi Water Reclamation Plant, which will help meet future demand for used water treatment, was issued on Thursday (Jun 23), said Singapore's national water agency PUB.

In a press release, PUB said the expansion will be completed by end 2019 and will add another 44 million gallons a day (mgd) to the treatment capacity of the plant. The tender includes civil and infrastructural expansion works as well as the installation of advanced membrane bioreactor (MBR) equipment.

The MBR treatment module will be increased in two phases of 22mgd each, in tandem with used water flow projections, it added.

Commissioned in 2008, the Changi Water Reclamation Plant is touted to be one of the largest and most advanced water reclamation facilities in the world. It has an initial treatment capacity of 176 mgd, and treats about half of the country's used water and produces treated effluent, which is used as feedstock for NEWater production, PUB said.

NEWater currently meets 30 per cent of Singapore's water demand, and this is set to increase up to 55 per cent in the longer term, the agency added.

“With this expansion, Changi WRP will be one of the world’s largest membrane bioreactor facilities. More importantly, it will produce more treated used water effluent for NEWater production and increase our water recycling rate, which will allow us to ensure a robust and sustainable supply of water for Singapore’s future”, said Mr Yahya Abdul Ghani, PUB’s director of water reclamation (plants).
