Users throw their waste through the indoor chutes and outdoor load stations. The waste are dropped and stored in a storage section which is designed to temporary hold the waste between transport cycles. When the waste reached certain level or due to preset timer, the exhauster fan starts to create airflow from the primary air inlet into the pipe network. The Discharge Valve door opens automatically to unload waste from the temporary storage section into the pipe network to be transported to a sealed container located at the central waste handling facilities. The container is then collected and emptied at specific times by a flatbed armroll truck for final treatment.

This system is suitable for residential developments. Hopper doors are specifically designed to restrict bulky items to be thrown into the load station. These bulky items are usually recyclables. Users are encouraged to separate waste at source and take recyclable items to the designated area.

STREAM Gravity Vacuum System is integrated with safety mechanism. It is safe and suitable for all users including children.
