75 Pneumatic Waste Conveyance System As part of HDB’s efforts to enhance the overall living environment of residents, the Pneumatic Waste Conveyance System (PWCS) was introduced to newer towns/ districts such as Punggol, Bidadari and Tampines North. What is PWCS? PWCS is a smart refuse collection system that uses high-speed air to automatically transport refuse from residential blocks to a centralised bin centre via a network of underground/ suspended pipes. The refuse is then processed and compressed into containers before being towed away for disposal. Benefits of PWCS PWCS is a fully enclosed refuse collection system, which helps to reduce foul smells and deter pests from scavenging around the chutes as they are now sealed. PWCS eliminates the need for refuse collection at each residential block. The land that would otherwise be needed for service roads and refuse handling equipment can be used for greenery instead, thus creating an enhanced living environment for residents. All the residential refuse served by PWCS are collected at the centralised refuse collection centre. As such, there will be fewer refuse collection trucks moving around the neighbourhood, therefore enhancing the road safety within the estates.

Similar to all refuse chute systems, using the PWCS incorrectly can cause chokages or a breakdown in the system, inconveniencing you and your neighbours. To avoid this, please dispose of your refuse correctly according to the following guidelines: The size of refuse bag should be smaller than the hopper opening. Note : You may contact your Town Council if you require assistance in disposing bulky items. To prevent chokage and fire in the PWCS, please DO NOT throw the following items into the refuse chute: HDB InfoWEB: www.hdb.gov.sg SingaporeHDB
