Concrete Washout Systems, Inc

CWS is based in Sacramento, California where the founder Mark Jenkins designed and built the very first washout container. We're very proud to have sold thousands of washout containers to individual service providers across the country and even beyond.   Our products, along with a wonderful network of customers, have saved the soil and water from millions of gallons of caustic waste - watery slurry that typically has a pH over 12, similar to Liquid Drano!

We hope you can take a minute or two to look about our website. At the very least, you'll become acquainted with what has become the gold-standard in containing and removing a harmful pollutant. If you think that CWS products might be a good add-on for an existing business or if you're looking to branch out into something new, we would be delighted to hear from you.

CWS founder, Mark Jenkins, is a concrete contractor and a waste hauler.  One day, after pouring concrete, he went to wash out his concrete equipment in an unused portion of the construction site when he was directed by the site superintendent to a clumsy arrangement of hay bales draped with sheet plastic and told to rinse out there because the local storm water regulators no longer allowed washing out directly onto the ground. 

Well, this particular 'washout pit' was a mess with hay bales falling over and punctured plastic doing nothing at all to keep the washout pollutants from entering the environment. What's more, while such a 'washout pit' was lot of trouble to build and maintain, the residual concrete couldn't be recycled with the sheet plastic and concrete mixed together. Developing a roll-off container for this purpose became an obsession.  The container had to be built for heavy duty use - the sides and bottoms, as structural components, had to be protected from wear or risk a potentially dangerous failure. The ideal solution would have good capacity and accommodate concrete pump trucks. 

The result is a simple, award-winning and patented container that essentially created the concrete washout service industry. Thousands of containers have been sold to independent washout service providers throughout the country and beyond.

As for Mark Jenkins, he's here and still loving every opportunity to get another customer up and running.
