Twenty-eight HDB projects in towns such as Tampines, Bidadari and Punggol could get new rubbish chute hoppers to prevent residents from disposing of bulky items into the chutes.This comes after instances of chokes in the pneumatic waste conveyance system (PWCS), caused by the improper disposal of bulky items and renovation debris, were reported by The Straits Times in 2025.The Housing Board on April 27 called a tender for the supply and installation of full volume-controlled refuse chute hoppers – the doors to the rubbish chutes – which have a smaller opening and a mechanism at the back to prevent the disposal of large or long items into the refuse chutes.The chokes are often caused by indiscriminate dumping of items such as large cardboard boxes, curtain rods, mop handles, buckets and renovation debris.The new hoppers are set to be retrofitted in older Build-To-Order (BTO) developments that use the PWCS.Tender documents on government procurement portal GeBIZ stated that the hopper must be designed to accommodate bagged waste measuring at least 30cm in diameter, but no more than 80 per cent of the conveyance pipe’s diameter.
