Rein in number of swimming pools to save water

There seems to be more and more private swimming pools nowadays, with practically every condominium, executive condo and even private home here having one.

Such a scarce resource should not be used so extensively in such a manner here, especially with water levels falling amid the current dry spell ("Water levels low at Singapore's main source"; March 23).

Private owners of swimming pools should be made to pay a much heavier levy for the water they use to fill their pools.

There could even be a bidding system - similar to the certificate of entitlement (COE) system - where home owners must bid for a COE to build a private pool.

Perhaps the number of public swimming pools here should also be reduced to save water.
