Is it necessary to install a domestic water filter (including that incorporated in a drinking fountain or other similar water using apparatus)?

The quality of the water supplied by the WSD up to the customer's building or the lot boundaries of the building conforms to the Guidelines for Drinking-water Quality recommended by the WHO and is stringently monitored through extensive sampling at treatment works, distribution networks and customers' taps. The WSD, in normal circumstance and where not necessary, does not recommend installation of any water filters. One of the major reasons is that they may have an opportunity to become an ideal breeding ground for bacterial growth and give rise to health hazards if they are not properly maintained.
