Western Riverside County Regional Wastewater Authority

Hallsten truss supported aluminum cover systems were included as part of the Western Riverside County Regional Wastewater Authority’s expansion and improvement plan to minimize odors coming from the treatment plant. A total of three covers were provided by Hallsten Corporation for this project. The two circular and one rectangular cover systems were designed to allow plant personnel to walk comfortably across each cover to access, service and maintain the tank equipment from above, while keeping gasses and odors contained beneath the covers.
