Process Wastewater Technologies LLC (PWTech) was formed in December 2006 as the residual manufacturer of wastewater and combined sewer overflow (CSO) products when the parent company in the U.S., CDS Technologies, Inc. was sold to CONTECH Construction Products Inc.

As a manufacturer and supplier of Volute™ technologies for sludge thickening and dewatering, and screening products primarily utilized in the CSO/SSO market, we’re proud to offer the best available technologies in the applications they serve throughout North America.

The company is based out of Rosedale, MD, and does all the manufacturing utilizing only American-produced stainless steel. There is no carbon steel used, which is a claim very few manufacturers in the industry can make.
