Cost of Service Study Update Professional Services

The San Dieguito Water District in Encinitas, California, is seeking a qualified contractor to conduct a comprehensive potable and recycled water rate cost of service study update. The agency needs to review current financial and operational information to align water rates with agency priorities and external factors. This project aims to establish equitable, cost-based water user rates for all customer classes over a three-year period while ensuring compliance with standard California industry practices. The scope of work requires the development of a ten-year rate and financial planning model in an Excel format for agency staff use. The selected contractor must calculate the total cost of purchasing, treating, and distributing water, and identify primary cost components along with their percentage of total rates and charges. Additionally, the study must calculate pass-through increases for specific costs as defined by the agency and review various potable water rate structures. Eligible bidders must be onshore organizations based in the United States. The agency requires the selected contractor to perform all work onsite in Encinitas, California. The agency is currently looking for proposals to determine the budget for this project, and bidders must submit all clarifying questions no later than June 15, 2026.
