Sewer Hog jetting system, from Brendford Environmental Systems, uses 2,000 psi (13,790 kPa), 350 GPM (79.5 m³/hr) to clean large diameter sewers, siphons, combined sewer overflow tunnels, and storm sewers [[Environmental XPRT:2020]].

The 2,500-gpm pump pushes slurry to the Grit Gator, a closed-loop, high-speed separation and dewatering container where solids are captured. Solids-free (up to 98%) greywater is returned to the sewer line. Moisture content of the captured debris is then reduced to a level that meets Paint Filter Test requirements and allows disposal in a landfill as dry material [[Wodalski2011]].
