Mill Creek Wetlands Water Quality Monitoring and Reporting

Project Description: The Project is one component of the City of Ontario's strategy to treat discharges from the City's target municipal separate storm sewer system (MS4) watershed, including New Model Colony. Flows will be diverted from Cucamonga Creek, which currently carries storm runoff, nuisance flows, and treated wastewater from an approximate 77 square-mile watershed that includes the cities of Ontario, Chino, Rancho Cucamonga, and Upland. The Project includes the construction, operation, and maintenance of a diversion pipe and a series of wetland ponds for the purpose of regional water quality treatment of urban runoff. These facilities will be located in uplands adjacent to Cucamonga/Mill Creek.
