Several residents of Bishan St 13 Blk 181 are reporting occasional instances of yellow-coloured water coming out from their home taps. According to two tenants at one of the units, on two separate occasions on Dec 19 and Dec 27, the water turned yellow and found contaminated with sand. On both incidents, the water supply turned back to normal only after 30 mins.
The Public Utilities Board (PUB) claimed that they self-diagnosed the incidents on Dec 29 following complaints from the residents, and found no fault with the piping system and water supply. The spokesperson for PUB then lamented the authorities will keep in view of the situation.
