Reservoir beneath Bidadari

Reservoir beneath Bidadari

SINGAPORE - The future Bidadari estate will lay claim to a unique feature - Singapore's first underground service reservoir built on low, instead of high, ground.

Holding enough water to fill three Olympic-size pools, the tank will be built beneath the town's planned park to save on surface space and keep the surroundings unmarred.

The land above it will be "integrated with the surrounding park amenities, hence optimising land", PUB said on Tuesday, adding that high ground available for service reservoirs is "limited".

The Bidadari reservoir could pave the way for more such underground tanks on low ground.

"Where possible, PUB will work with other agencies to explore a similar concept in other new areas," said the national water agency's spokesman.

Service reservoirs store drinking water to regulate supply to homes and boost water pressure during periods when demand is high.

There are 14 such reservoirs now, but all are located on high ground such as Mount Faber and Fort Canning, letting gravity do the work in channelling the water to homes.

In contrast, the Bidadari reservoir will have a pumping station on a 200 sq m plot of land atop it.
