Similar to the water detention tank built in Opera Estate near Siglap in 2001 that has reduced floods in the area from four to six times a year to almost none, PUB unveiled plans for a bigger version of the water-detention tank to be built under a new carpark for coach buses at the Botanic Gardens by 2015.

The Gardens tank, with a 38,000 cubic metre capacity (about the volume of 15 Olympic-sized swimming pools), is expected to be 1½ times larger than the Opera Estate tank.

PUB said the new tank will hold rainwater temporarily during storms and pump water back into the drainage system after the storm ends. The rainwater from the tank could also be used to irrigate the greenery in the Botanic Gardens and nearby Dempsey area.

This is one of PUB’s two new infrastructure projects to keep Orchard Road and surrounding areas dry. The other major project, to be completed by 2017, is a canal that will divert rainwater from the over-stressed Stamford Canal to the Singapore River.

In the 1990s, when ENV embarked on a S$1-billion Scheme to build "COmpact and Covered" Sewage Treatment Plant (now called Water Reclamation Plant) with the aim of reducing the buffer distance from 2-kilometer to 500-meter and eventually right to the boundary of the Sewage Treatment Plant where communties living in an integral environment like in Japan.

In the design competitions, there were wonderful pictures on tennis courts, football feilds, sport clubs, etc on top of the covered sedimentaion tanks, bioreactors, etc.

Why can't we adopt a simialr integrated scheme for this 38,000 cu. m. underground retention tank?
That is, build an underground membrane-based filtration water treatment plant, abut or on top of this retention tank..or even opposition of the road at Dempsey Camp or Golf COurse or that sprawling public carpark?

We can built an oviod or speriod water storage tank about 30-metre or RL 130.000, connected to public watermains to increase water pressure as well.

These Water Sotrage Tank Tower can be aesthetically designed liek a "Gigantic Tree" with hanging gardens, maybe an infinity-edged public swimming pool on top or sports club on top......

WHy not "sustianable development" with Botnaic Gardens self-sufficiency in water consumption, selling surpluses to PUB....
All the sludge and sand collected from primary filtration to recycle for land reclamation.

Instead of wasting eenrgy to pump the stored water back to the Stamford Canal, why not just build a water treatment plant to re-sue those rain-water?

Water technology is avaialble.
Water demand is great for Botanic Gardens.

WHy not think out of the box as to how to integrate a water treatment plant within a community called "sustainable devleopment of an Eco-City"?
