General work description:  

The City of Isleton (City) is comprised of an area of approximately .49 square miles in Sacramento County (County), California. It is a rural community located in southwestern Sacramento County with a racially and ethnically diverse population. The City is located off of Highway 160 between Walnut Grove and Rio Vista. It is a residential, industrial, and commercial city in the heart of the California Delta within the Sacramento County of California. The wastewater collection facilities that serve the City are owned, maintained, and operated by the City Sewer Division under the City’s Public Works Department.

The City owns, operates, and maintains the City’s wastewater collection system with approximately 6 miles of sewer main lines and 1 lift station. The treatment system for sewer is evaporation/percolation, ponds of about 1,700,000 square feet. The System services the entire City and a remote Site-Oxbow Marina. Additionally, the City plans on adding about 30 homes on Tyler Island Bridge Road immediately adjacent and contiguous to the City.

The City is requesting statements of qualifications from qualified firms to prepare a comprehensive wastewater (sewer) rate study. The purpose of this study is to prepare a cost of service study, validate the appropriate rate structure, and recommend rates for the City that generate adequate revenue to cover:

1. • Current and future operations and maintenance costs based on established and anticipated regulations and industry best management practices;
   • Rate stabilization;
   • Capital repair and replacement costs based on age and condition of infrastructure and systems;
   • Major Capital Improvement project costs;
   • An adequate reserve fund;
   • Required debt coverage; and
   • Necessary studies to maintain an efficient and resilient utility.

The study will analyze a 20-year period and develop a 5-Year Rate Structure that is in compliance with the California Proposition 218 requirements. The City has recently completed a sewer master plan, a copy of which is available upon request. The last sewer rate study was completed in 2012.
