Abstract
A sewer cleaning system includes a water tank, a pump operatively coupled to the water tank, a water hose operatively coupled to the pump, a vacuum-generating system, a vacuum hose operatively coupled to the vacuum-generating system, and a debris tank having a forward bulkhead defining a fluid chamber. The bulkhead includes a debris sieve configured to allow water in the debris tank to flow through to the fluid chamber while retaining particulates in the debris tank. The sewer cleaning system further includes an extraction pump in fluid communication with the fluid chamber and configured to extract the water in the fluid chamber. The extraction pump is in fluid communication with the water tank so as to send the extraction water from the fluid chamber to the water tank for re-use. A method for cleaning a sewer line is also disclosed.
