When the City of Riverside, CA searched for solutions to meet California’s Trash Amendments* for stormwater, they approached CleanWay Environmental Partners to conduct a pilot program for Full Capture Trash Treatment Control Devices. We were singled out based on our long experience and strong reputation nationally for solving stormwater filtration, metals removal and wastewater treatment challenges.
Innovative, Modular Curb Inlet & Drop Inlet Filtration Systems
Our partnership with the City of Riverside specifically addressed the development of innovative, modular Curb Inlet and Drop Inlet Filtration Systems. To meet the rigid California standards, our systems are scalable to meet peak flowrates regardless of inlet size; trap all particles down to the 5mm level; does not bypass trash and eliminates upstream diversion. Unlike other systems, the CleanWay solution maximizes catch basin drainage, depriving mosquitoes of breeding habitat, a critical criteria for certification.
“We strive always to design and manufacture products that are useful, practical and deliver long-lasting utility. It’s been our great privilege to work with the Riverside team, and to join the exclusive list of manufactures with products that meet the rigid California Trash Amendments standards.”

Maximum Capacity, Modular & Scalable by Design
The CleanWay systems address several key design considerations: The filtration units perform in heavy commercial and residential use urban environments with high trash volumes and under historically high storm flow rates; they fit curb inlets ranging from 10’ to 30’ in length; and the filtration basins are scalable to manage varying volumes at each existing inlet structure.
Unique Challenges Met & Expectations Exceeded
Significantly, the CleanWay system is comprised entirely of perforated stainless steel that folds flat to fit into the narrow inlet opening — then unfolds inside the existing basin structure to occupy virtually the entire existing catch basin volume. The structural rigidity of our system maintains trash catch basin volume under maximum trash/water loading, unlike flexible mesh systems and other inferior alternatives. An integrated, under curb rail system allows the stainless catch baskets to slide out of the way for access to the existing inlet and basin structure and associated piping for ease of maintenance and repair. Our fold flat design also reduces shipping costs, and resolves storage and delivery-to-site issues.
"This was a perfect opportunity for us to apply the knowledge, problem solving ability and fabrication expertise we've applied to similar non-point pollution and stormwater trash abatement challenges in the Pacific Northwest and beyond for over 20 years. Every project is a chance to innovate and refine our products in collaboration with our municipal, state, industrial and commercial partners, and the Riverside project was an exemplary case in point."

*In 2015, the State Water Board adopted an Amendment to the Water Quality Control Plan for Ocean Waters of California (Ocean Plan) to Control Trash and Part 1 Trash Provision of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries (ISWEBE Plan). Together, they are collectively referred to as 'the Trash Amendments'. The project objective for the Trash Amendments is to provide statewide consistency for the Water Boards' regulatory approach to protect aquatic life and public health, and to reduce environmental issues associated with trash in state waters.
