Sludge Projects, Tank, & Digester Cleaning

CWM has the experience and the right equipment to tackle even the most complex sludge and clean-out projects. We have over 20 years experience servicing municipalities, power plants, industrial facilities, and more.

Employees are certified with confined space training on a bi-yearly basis, and we hold every class and subclass of water (A-E & 1-14) and wastewater (A-E & 1-4) certification.

Our fleet includes vacuum trucks, a combination Jet/Vac truck, crane trucks, and hydraulic grinder/chopper pumps. All drivers hold current commercial driver’s licenses with tanker endorsements. Our portable belt filter press combines a sludge thickener and press into one unit. This technology provides excellent dewatering and produces a bio-solids cake for land application or landfill disposal. Our portable trailer means the press is small enough to fit in almost any space but big enough for any size job.
