Abstract
A method and system to recycle water for hydro-excavation includes a vacuum hose to remove a slurry of solids and liquid from hydro-excavation at a site. A debris tank is in fluid communication with the vacuum hose and is used to collect the slurry. The system also includes a filter drum, where a portion of the filter drum is configured to rotate through the slurry to filter the liquids from the solids, where dewatered solids are returned to the site for compaction. In addition, an outlet is in fluid communication with a central portion of the filter drum to return filtered water for use in hydro-excavation at the site.
