SINGAPORE : Singapore’s largest and most advanced water reclamation plant — the Changi Water Reclamation Plant — will open next week.The pumping station at the new Changi Water Reclamation Plant is as high as a 25—storey building.
The station collects all used water from the deep sewerage tunnels via gravity.
The water then undergoes a treatment process at the plant before being discharged into the sea.
Part of that treated water will be processed into NEWater when the NEWater plant, which is being built on the rooftop of treatment facilities, is ready.
The NEWater factory which will be operational by May next year can produce 50 million gallons of treated water daily.
This is equivalent to the volume of water in 90 Olympic—sized swimming pools.
PUB said the Changi Water Reclamation plant stands out in its land use.
"The designers have incorporated a space saving design concept — things like stack treatment tanks and also stack treatment facilities like our sludge treatment facilities. All the treatment facilities are stacked on top of the other so as to save space," said Yong Wei Hin, assistant director of Changi Water Reclamation Plant.
Such a concept is the first in the world. With the stack concept, the Changi Water Reclamation Plant takes up only 32 hectares of land, which is about the size of 45 football fields.
PUB said that without this concept, it would have needed 3 times more land for the construction of the plant.
Another unique feature of the reclamation plant is a Sludge Dryer, which reduces the volume of sludge to be disposed. The sludge will then be incinerated and used as landfill.
PUB said the completion of the Changi Water Reclamation Plant concludes the first phase of its Deep Tunnel Sewerage System — a used water superhighway.
The second phase of the project will see a similar reclamation plant built in Tuas. It is expected to be ready in 10 to 20 years’ time.
The Changi Water Reclamation Plant, which costs some S$3.7 billion to build, can treat 176 million gallons of water per day. This is equivalent to the volume of water in about 320 Olympic—sized swimming pools.
And with its completion, PUB said a few of the existing water reclamation plants will be shut down.
Two such reclamation plants — in Bedok and Kim Chuan — have already ceased operations. — CNA /ls
