Manhole Cleaning
Manhole mainly collects sewage from the ground. After heavy rainfall, fragments may accumulate inside the manhole, and large garbage may also block the drainage system. High pressure injection and vacuum pumping are used together to unblock the manhole. In addition, we could also clean and dispose bulky wastes which are on the manhole and drain.
Workflow*
1. Clean the bulky wastes on the drain
2. If there is blockage, high pressure injection and vacuum pumping will be used
Advantage
