Having versatile, powerful, easy-to-use equipment is important for the city of Waukesha, Wisconsin’s, Wastewater Treatment Department, which is charged with maintaining some 256 miles of sanitary sewer lines and 8,000 catch basins to handle storm runoff.
“With three crews flushing lines daily, we handled about 226 miles of sewer lines last year,” said Jon Weinkauf, the city’s fleet manager.
The latest addition to Waukesha’s equipment fleet is a Vacall AllJetVac combination sewer cleaner, well-equipped for efficient sewer line maintenance work with exceptional power to break up sewer line blockages and maintain flow with strong jetting and vacuum forces.
“When we tried the machine on a demo, we had a 6-inch storm sewer line where the contractor had dumped some leftover concrete mixture,” Winkauf said. “We were able to open it up with the Vacall and a cutter nozzle, and everybody agreed that it did a great job, and it was exceptionally easy to use.”
The city of Waukesha acquired the machine, which has jetting power up to 3,000 psi and vacuum power up to 120 gpm using a positive displacement system. They selected an R Series model, with the hose and reel assembly located at the rear of the machine, where operators said it is quieter and easier to use. The machine also has an 8-foot, 6-inch boom, capable of 270-degree rotation.
“With wireless remote controls, we have the option to raise and lower the boom at the same time, and that’s something else the operators appreciate,” said Joe Baginski, the city’s street division supervisor. “They also like to be able to use the remote to dump debris from a safe distance, which other models cannot do.”
The wireless remote is an optional HBC device that is compact in size and has an easy-to-manage harness. Among other convenient, productive options on the machine are automated electronic controls, a tank flush system, a cold weather package, extra lighting, hose reel management devices and a hydro excavation package. It also has a 1,500-gallon water tank and a 12-cubic yard debris tank with a galvanized finish, both with lifetime warranties.
“We like the simplicity of the design, which makes it easy to operate and service,” Weinkauf said. “Plus, we find it to be very functional and reliable, and that’s important for us to accomplish the work we need to get done for the city every day.”
