A mobile sewer and catch basin cleaning vehicle dislodges and removes debris in a conventional manner. The dislodged debris is then conveyed into a debris-receiving compartment where it undergoes a two-stage filtration process. The first stage removes the coarser debris from the reclaimed contaminated water. The second stage filters out the finer particulate debris by drawing such water through a finely filtered media surrounding a rotating drum. This filtered reclaimed water is then re-used in the cleaning operations. The extremely fine filtration media is continually cleaned by small amounts of clean water being applied at high pressure through nozzles designed to spray the entire media area as the drum rotates.

A method for using a vehicle for recycling water used to clean piping system associated with sewer laterals and catch basins, the vehicle having a debris-receiving container and a water reservoir for storing water, comprising the steps of: (a) injecting water from the water reservoir under pressure into the piping system to loosen the debris located therein; (b) pneumatically conveying the water and loosened debris from the piping system into said debris-receiving container; (c) drawing the water so conveyed through a fine filtration media located in a portion of said debris-receiving container to remove debris from such reclaimed water, thereby producing filtered reclaimed water; and (d) injecting said filtered reclaimed water into the piping system by by-passing entirely the water reservoir to continue the cleaning of the piping system.
