  • Role of the Sacramento Area Sewer District (SASD)

– Local collection system (design flow < 10 MGD) – Provides service to unincorporated Sacramento County, Elk Grove, Citrus Heights, Rancho Cordova, and parts of Sacramento and Folsom – Over 1.2 million people served – Over 4,400 miles of sewer pipe (mains and laterals) – Over 100 sewer pump stations – Facilities needed for development are constructed by developers and given to SASD

  • Role of the Sacramento Regional County Sanitation

District (Regional San)

– Regional wastewater conveyance (design flow > 10 MGD) – Wastewater treatment and disposal – Provides service to SASD and the Cities Sacramento, West Sacramento, and Folsom – Over 140 miles of interceptor sewer pipe – Treats 150 MGD average with capacity of 400 MGD – Typically constructs their own facilities

Planning Documents

  • Water Supply Master Plan

– Identifies water demands – Describes water sources and facilities – Provides financial analysis – Broad overview

  • Water System Infrastructure Plan

– Planning and implementation tool – In depth facility planning

  • Urban Water Management Plan

– Projects water supply and demand over 25 years in 5-year increments for different water year types (i.e. wet and dry)

Planning Document Updates

  • Water Supply Master Plan

– Requires amendments to include proposed growth areas – Draft amendments need Board approval

  • Water System Infrastructure Plan

– Draft is complete and moving through approval process – Update supported development of the Master Plan amendments

  • Urban Water Management Plan

– Currently being updated, informed by the Water System Infrastructure update and Master Plan amendments – Scheduled for Board approval in June of this year

Planning Document Updates

Water Supply Assessment

  • Shows whether adequate water supply has been

planned for each development

  • Required by California Water Code
  • Uses information from other planning documents
  • Will be developed as part of CEQA Process

Water Supplies – Conjunctive Use Program

  • Provides for a balance of surface water and

groundwater use

  • Provides system flexibility to ensure protection of

both groundwater and surface water resources

  • Provides for reliable water service
  • Introduced surface water into basin through the

Freeport intake on the Sacramento River treated at the Vineyard treatment plant
