GN designs and manufactures a hydro-vac sludge processing system. It is also called hydro-vac sludge waste treatment or sewage sludge management system. The sludge processing solution is to use liquid and solids separation equipment to treat the soil, soup, or sludge generated by the Hydrovac or HDD project and produce reusable material for construction and clean water discharge. Normally, the slurry is free of contaminants and comes from the physical location of utilities in the public right-of-way and from directional drilling for laying underground pipes or utilities or other privately owned construction.
Features of the GN Hydrovac sludge processing equipment
- Full package design for turnkey solutions

Hydrovac Excavation Introduction:
Hydrovac excavation is a non-destructive, precise, non-mechanical process that uses pressurized water and an industrial-strength vacuum to simultaneously excavate and evacuate soil. As the pressurized water breaks up the soil, it creates laitance that is removed using a powerful vacuum in a waste tank. Hydrovac is currently the only non-destructive process method for the excavation operation. Hydrovac excavation can efficiently and accurately excavate in a variety of soil types and environmental conditions, including frozen ground conditions, clay, hard-packed earth, and in remote areas or locations with limited access. Residual slurry from the Hydrovac excavation will be sent to the Hydrovac slurry processing plant for treatment to recycle the water and construction material.
What type of material can the GN Hydrovac sludge processing system handle?
- Soil / Soup / Mud (mud) generated from hydro-vac excavation
- Horizontal directional drilling mud
- Shield tunneling machine for sludge
- Mud treatment of bored piles.
- Other construction sludge waste
