Business Sewer Public Benefit Program

The Sewer Public Benefit Program is an incentive program for qualifying City of Riverside businesses. The program encourages reductions in the intensity and quantity of discharge to the sewer system. Such reductions create benefits in the form of reduced wear and tear on the collection system, chemicals used for treatment, and operations and maintenance costs. These benefits are shared by all customers. Funds for this program are capped at $400,000 per year.

Program Objective

The Sewer Public Benefit program was developed to educate the City of Riverside commercial, institutional and industrial sewer use customers on enhanced pretreatment technologies and the corresponding water conservation and sewer system benefits, and to offer incentives toward the installation of such technologies.


Program Highlights

The Sewer Public Benefit Program incentivizes reductions in pollutants which result in excess sewer collection and treatment costs and is based upon the facilities ability to reduce the strength and/or volume of its discharge beyond levels required by local limits. Incentives of up to 50% of the cost to install retreatment equipment may be offered.

Pollutants for which a reduction can be incentivized are flow, Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), and Fats, Oils, and Grease (FOG). To qualify for an incentive, a business must agree to a reduction goal, provide annual progress reports toward meeting the goal and meet all other program requirements.

Pollutants other than Flow, COD, TSS, and FOG that potentially increase sewer collection and maintenance costs may be incentivized as well. Such pollutants, along with corresponding incentive amounts, will be considered on a case-by-case basis. All are encouraged to apply.


Program Business Incentives

Incentives are available for existing and new sewer use customers. Existing Customers are industrial or institutional businesses which have operated in the City of Riverside with a valid business license prior to September 23, 2008. New Customers are those which have operated with a valid business license after September 23, 2008.

Existing customers are eligible for incentives for up to 50% of the cost to install pretreatment technology, not to exceed $150,000 per year, per customer. The total incentive awarded shall not exceed 50% of the accounts total preceding 12 month sewer service charges.

New Sewer Customers

New customers who will discharge at pollutant levels greater than existing local limits are subject to supplemental capacity charges during permitting. New customers are eligible for incentives of up to 50% of the cost to install pretreatment technology, not to exceed $150,000 per year, per customer. The total incentive awarded shall not exceed 50% of the Supplemental Capacity Charge.


The City of Riverside, on a case by case basis, may consider incentives over $150,000/year/customer for new facilities installing pretreatment equipment that is above and beyond what is required to meet City Local Limits. These projects would follow the SBP process for consideration and, if approved by the program administrator would require concurrence with the Public Works Director and then would require City Council approval.
