Trunk sewers are not self-cleaning and most of them are up to 80% full of debris – robbing your system of vital capacity and contributing to sewage overflows and environmental degradation. Robichaud specializes in cleaning large diameter trunk sewers, using specialized equipment, talented technicians, and the right plan.
Using special techniques, debris is captured in tanks. Any water mixed with debris is returned to the sewer and the tanks filled with the de-watered debris are taken to a landfill site. Often the debris will pass the Regulation 309 Leachate Extraction Tests, and can be disposed of at a reduced rate, resulting in substantial savings over traditional cleaning techniques for infrastructure owners.
