SedVac® Sediment Dredge System
The SedVac Sediment Dredge System is a sediment removal system designed to clean your clarifier by effectively removing the compression zone layer of sludge. Unlike clog-prone vacuum pipes, the SedVac system can handle high concentrations of sludge and grit and is capable of consistently removing solids of 3% concentration across a wide range of influent quality. Its unique header wing design features 4-inch-high intakes that significantly reduce the opportunity for clogging and remove much less water than competing systems.
SedVac also provides a unique cost advantage for sludge removal in long-length tanks. Where traditional chain and flight systems would require additional chain, flights, tracking, wear shoes, and associated components, the SedVac unit only requires a hose and an extended track assembly.
Advantages

Maintains flow rates & resists clogs
Supports both vacuum & pump configurations
Navigate Within Water & Wastewater
Components
Triangle-Shaped Header
Chassis
Traction Winch System
Track Assembly
Flexible Wipers
Pumps
Triangle-Shaped Header
SedVac’s triangle-shaped header departs from traditional industry designs in order to address common clogging issues. The 4-inch-high intake engulfs sludge at its densest level, handling sediment loadings up to 3 percent and cleaning all the way down to the floor.
Chassis
Our unique chassis design is the crux of the SedVac system, capable of withstanding the pulling power of our winch systems and the harsh elements of submerged environments.
Traction Winch System
SedVac’s no-slip traction winch provides positive movement at programmed speeds and cycles within short and long basins up to 380 feet.
Track Assembly
The track assembly keeps the system secured to the floor, preventing binding and derailing. Its design makes it easy to install and requires minimal infrastructure changes.
Flexible Wipers
SedVac’s flexible wipers scrape the floor and walls of the basin clean.
Pumps
Pumps are available in various flow rates to handle the toughest of facility sediment loadings.
Featured Installations
Okatie, South Carolina
Application
The Beaufort-Jasper Water & Sewer Authority required a sludge removal system with a low profile for easy integration below tube settlers. SedVac was chosen based on its ability to be incorporated into the existing basin with minimal infrastructure changes and its successful pilot at the facility – it removed twice as much sludge in half the time and wasted 50% less water than competing vacuum pipe systems.
Tiffin, Ohio
Application
The Aqua America plant in Tiffin sought a cost-effective, automatic solids removal solution that would eliminate the tedious, time-consuming process of taking the tanks down for maintenance. SedVac enabled Aqua America to cut down on sludge removal frequency, delivering cost savings and reliability despite fluctuations in influent water quality.
