Sacramento Power Authority Cogen Project

Overview

Sacramento Power Authority Cogen Project

Regional San is working collaboratively with Sacramento Municipal Utility District (SMUD) to convey recycled water to the Sacramento Power Authority (SPA) Cogen plant in south Sacramento for use in its cooling towers. When implemented, the project would provide approximately 1,000 acre-feet per year, or one million gallons per day, of recycled water in lieu of current potable water use.

Using advanced treatment processes, the Sacramento Regional Wastewater Treatment Plant (SRWTP) will produce high-quality recycled water that will be conveyed through “purple pipes” to the SPA Cogeneration plant located approximately six miles north of the SRWTP.

Construction Updates

Construction crews are currently working on the pipeline segment located west of the SPA cogeneration plant along 47th Avenue. Remaining construction tasks include clean-up and road paving along the entire alignment. Once all construction is completed, the pipeline will connect to the SPA cogeneration plant located near 47th Avenue and Franklin Boulevard. Completion of construction is scheduled for fall 2017.

Project Benefits

This project has numerous regional and environmental benefits, including:

  • Conserves potable surface and groundwater supplies
  • Reduces discharges of treated effluent
  • Compatible with allowed uses of recycled water
  • Provides a sustainable water supply for industry
  • Helps to meet local, regional, state and federal water recycling goals

Project Elements

This project includes the following elements:

  • Level of treatment will be Title 22 tertiary recycled water
  • Recycled water will be supplied by SRWTP
  • Approximately six miles of pipeline construction
  • Recycled water demand will be about 1,000 acre-feet or one million gallons per day

Costs and Funding

The preliminary cost estimate for constructing the recycled water piping system is $15.2 million. In May 2012, the SPA Cogeneration Project received a $40,000 grant from the United States Bureau of Reclamation’s Watersmart Program to support the preparation of a feasibility study for the project.

In addition, Regional San applied for and received grants through Proposition 50, Proposition 1 and Proposition 84 totaling approximately $8,080,738 million. Regional San also secured approximately $8,182,200 in a low interest loan through the State Revolving Fund Loan Program. The grants and loan will help fund the design and construction of the project.

Funding for this $3,500,000  Regional San / SPA / City of Sacramento Water Recycling Pipeline Project – Phase 1B Project has been provided in full or in part by Proposition 1 – the Water Quality, Supply, and Infrastructure Improvement Act of 2014 and the Clean Water State Revolving Fund through an agreement with the State Water Resources Control Board. California’s Clean Water State Revolving Fund is capitalized through a variety of funding sources, including grants from the United States Environmental Protection Agency and State bond proceeds.
