Written answer by Ministry of National Development on Preventing Excessive Water Ingress into Motor Rooms of Lifts at Older HDB Blocks Given Monsoon Surges

Feb 4, 2025

Question No: 7099

Question by: Ms Ng Ling Ling

To ask the Minister for National Development given the monsoon surge from 10 to 13 January 2025 (a) whether the Ministry will conduct a review with Town Councils and provide resources for those that performed emergency repairs caused by excessive water ingress into motor rooms of lifts located in older HDB flats where the original drainage was not designed for such intense rainfall; and (b) what measures will be undertaken to pre-empt damage of such nature to minimise inconvenience to residents.

Answer:

HDB incorporates ventilation and drainage features when designing lift motor rooms. For example, lift motor rooms located on rooftops are designed with overhangs to prevent rainwater from splashing into the lift motor rooms, as well as discharge outlets which are sufficiently sized to drain heavy rainfall off the roof of the lift motor rooms.

In addition to design features, regular maintenance of rooftop drainage systems is key. This is particularly important during monsoon seasons or when prolonged wet weather is anticipated, where Town Councils are strongly encouraged to step up their inspections of drainage systems within their estates and carry out timely maintenance works where necessary. HDB has also stepped up in its efforts to support Town Councils in proper estate maintenance, including issues that arise with changing climate and weather conditions. In complex cases, HDB supports Town Councils by conducting joint inspections and providing technical advice, so as to identify and address root causes.

To offset the costs of estate maintenance, the Government provides substantial funding to Town Councils, amounting to almost $260 million annually. Town Councils should manage their finances prudently and cater a reasonable amount of contingency funds in their budgeting to cope with unexpected repairs.
