Assoc Prof Fatimah Lateef asked the Minister for the Environment and Water Resources with the increase in residential and commercial developments (a) how does the PUB address issues of lower water pressure in areas of these developments, especially during peak-utilisation hours; (b) what are the options available to residents to improve their water supply pressure; and (c) whether the PUB has a regular review mechanism to monitor this.

Dr Vivian Balakrishnan: PUB works closely with agencies such as URA and HDB in implementing water supply infrastructure ahead of new developments so that the distribution network is able to support the growing water demand.

There is a Code of Practice for Water Services that stipulates the requirements for the plumbing system so that the water pressure at customers' premises is adequate even during peak utilisation hours. Developments located on high ground are required to supply water through water tanks located on top of the buildings.

However, there are a small number of older private residences built prior to the introduction of the Code of Practice which are located on high ground and do not have a water tank. Over time, as new developments gradually increase the overall water demand in the area, these older premises could experience intermittent lower water pressure during peak usage hours. PUB monitors these areas closely and when such a situation occurs, PUB has boosted the water pressure to the area. For example, in the Tai Keng residential area, PUB has increased the water pressure to ensure residents continue to have adequate water pressure throughout the day.

The public can contact PUB through a 24-hour toll free hotline at 1800-2846600 for further assistance.
