Jet Power II®

Duke’s partners with cities to ensure sewer pipes not only stay free of roots, but also grease. Effective for grease removal in wet wells, manholes, lift stations and sewer lines, Jet Power II® is a grease liquefier that is non-corrosive, biodegradable, non-acidic and non-caustic and will not damage sewage treatment plants, pump stations or sewer jet trucks. Containing powerful surfactants that leave the sewer virtually grease free after just one pass, Jet Power II® is jet-sprayed upstream from the affected pipe.


A 1% solution of Jet Power II® is mixed in your high pressure jet truck. Only 10 gallons of Jet Power II® are needed to produce 1,000 gallons of solution and will treat approximately 1,000 feet of sewer pipe. The treatment requires only 10 to 15 minutes to liquefy grease, allowing you to quickly move on to jet spraying and retrieval. When jet spraying, pressure should be set to maximum PSI and reel speed, and we recommend using a rotating nozzle. The hose is stopped at the upstream manhole, at which point the water pressure is turned off. Roughly 10 minutes later the grease will be homogenized and pipes will be virtually grease free.
