The intent of this Request for Proposals (RFP) is to secure the services of one qualified Consultant to prepare a comprehensive rate model and complete a Cost of Service rate study and 5-year rate forecast comprised of: 1. Wastewater Connection Fees, 2. Monthly Wastewater Service Rates, 3. One Water Connection Fees, 4. Monthly Meter Equivalent Unit Rate, 5. Direct Recycled Water, 6. Recycled Water Fixed Cost Recovery, and 7. Groundwater Recharge Service Rates. In addition, the Consultant will develop alternative CBP cost allocation alternatives and associated impacts to various rates and charges for Agency staff to review and consider. Determination of the cost allocation for the CBP is the top priority before conducting the rest of the Cost of Service rate study. Once CBP cost allocation is determined, the Cost of Service rate study for FY 2027-2028 and 2028-2029 and the 5-year (FY 2027/28 through FY 2031-32) rate forecast will be completed that incorporates the allocation of CBP costs to the appropriate rates and charges, based on IEUA’s direction. The rate study will require close coordination with IEUA staff and require the Consultant to work incorporate input, as directed by IEUA staff, from IEUA’s sewage collection and retail agencies. The selected Consultant shall be well versed with developing wholesale and retail water, recycled water, and wastewater utility rate structures and be knowledgeable of all California codes, laws, and regulations as they relate to public agency finances (cities and special districts).
