ANG MO KIO NEIGHBOURHOOD III (Rusty water)

Mr Yeo Toon Chia asked the Minister for National Development whether he is aware that rusty water, caused by the corrosion of the unlined galvanised iron distributing pipes, is being supplied to some residents of Ang Mo Kio Neighbourhood III; and in view of this (a) what measures the Housing and Development Board (HDB) is taking to ensure that residents are supplied with clean water at all times; and (b) whether HDB will consider replacing the corroded pipes with corrosion-resistant materials.

Mr Teh Cheang Wan: Some apartment blocks at Ang Mo Kio Neighbourhood Ill have been getting rusty water as a result of corrosion of the galvanised iron downfeed pipes leading from the water tanks. The HDB periodically flushes the water tanks in these blocks. In addition, the Board has commenced replacement of the badly corroded iron downfeed pipes with stainless steel pipes.
