The Sewerage Systems Services Program provides for the collection, treatment and disposal of all wastewater generated within the City of Riverside and complies with State and Federal requirements governing the treatment and discharge of wastewater. Primary, secondary and tertiary treatment of wastewater from Jurupa, Rubidoux, and Edgemont Community Services Districts is also provided.

Administration and Support:

The Administration and Support program is responsible for providing the management necessary to assure the effective and efficient operation of the Sewerage Systems Division to demonstrate compliance with the National Pollution Discharge Elimination System permit. This includes coordination with the EPA, Air Quality Management District, the Regional Water Quality Control Board and other regulatory agencies. Sewer systems complaints are also handled by this section. Another responsibility of this section is to implement capital improvement programs and safety and training programs to comply with government regulations.

Collection Systems Maintenance:

The wastewater collection system includes over 1,100 miles of gravity sewers ranging in size from 6 to 48 inches in diameter. The system also includes eighteen wastewater pump stations, three of which are storm water pump stations. Most of the wastewater lift stations are designed for flows of 100 to 400 gpm. There are two large lift stations with design capacities in excess of 2,000 gpm. The three storm water pump stations have design capacities of approximately 500 gpm each.

Treatment Services:

The Treatment Services program is responsible for providing the effective treatment of all domestic and industrial wastewater generated within the City of Riverside and in the Rubidoux, Edgemont and Jurupa Community Services Districts. This entails the continuous efficient operation of the primary, secondary and tertiary treatment plant to produce high quality treated effluent that complies with 100% of all state and Federal requirements. Current flow treatment is approximately 30 million gallons per day.

Industrial Waste Inspection:

The Industrial Waste Inspection program is responsible for the enforcement of Federal, State and local regulations that pertain to the quality of industrial, commercial and industrial wastewater discharged into public sewer lines for reclamation at the City's Water Quality Control Plant. The program also includes responsibility to oversee the implementation of Edgemont, Jurupa, and Rubidoux Community Services District's (CSDs) pretreatment program.

Almost every type of pump and valve used in the wastewater industry can be found at the plant. Motors range in size from 500 hp down to 1/4 hp. Electrical instrumentation and controls range from old relay logic panels to modern PLC based systems to a state-of-the-art DCS control system. New construction is adding to the number and variety of equipment maintained at the plant. Projects to upgrade and replace old equipment are simplifying operation and maintenance and reducing the operational cost of the plant.
