Wastewater Covers & Storage Tanks

    When it comes to wastewater covers and tanks, no one can match CST experience and product selection. Many companies that have come and gone, but CST has been there since 1893 and will continue to be there well into the future. All CST wastewater tanks, domes, and flat cover products are manufactured in ISO 9001:2015 Certified facilities under the closest production controls. In addition to our lines of standard products, CST’s in-house engineering teams can provide custom designs and PE stamped drawings.

    CST is the leading manufacturer of aluminum covers and domes with over 20,000 installations worldwide.  Lightweight aluminum construction, hinged access, and modular designs make CST covers easy to install, easy to use, and easy to maintain. Whether the application requires extruded or formed, circular or rectangular, unsupported or supported, dome or flat, odor control or containment, full coverage or just lauder, we have the right solution to match each application all from one manufacturer – CST
