As part of HDB Greenprint to create sustainable public housing, residents at 38 residential blocks in Yuhua will be the first to experience the Pneumatic Waste Conveyance System (PWCS).
The PWCS is an automated waste collection system that uses a vacuum-type underground pipe network to collect household waste, which is then transported through underground pipes to a sealed container. Trucks then periodically collect the waste for disposal. The entire waste collection process is automated, thereby reducing manpower requirements and increasing productivity. Through the PWCS, the environmental and sanitary issues associated with open refuse collection methods are reduced.
The PWCS will bring about the following benefits:
Improved living environment
Please refer to the PWCS user guide for more information.
Flats built before 1989 use the Individual Refuse Collection System (IRCS) for waste disposal. Residents will dispose their waste through the hoppers and into the collection bin at the bottom of the refuse chute. The waste is then manually collected and stored at the bin centre before being removed by the National Environment Agency's (NEA) Public Waste Collectors.
