Both easements and public right-of-way provide land-rights for Central San to operate and maintain your public sewer and recycled water facilities.  The property owner owns the land and all the improvements within the easement that are not owned by Central San; and is responsible for maintaining their land and (allowable) improvements.  Central San owns the sewer/recycled water line(s) and all necessary maintenance access structures and appurtenances. The easement rights enable Central San to construct, reconstruct, renew, alter, operate, maintain, inspect, repair, and replace its facilities as may be needed without excessive cost or other undue difficulty.  Mainline Easements A property owner or developer seeking to install new public sewer or recycled water facilities to serve their properties must fund, design, construct and provide appropriate land-rights for the proposed public facilities in compliance with District Code and Standard Specifications (please see Section 9. Property Rights).  Wor​ding for Irrevocable Offers of Dedication on Subdivision Maps (Map Offers)   Map Offers Template for Irrevocable Offers of Dedications by Separate Instrument (IOD)    IOD   Surveyor Checklist for IODs Surveyor Easement Checklist Surveyor Exhibit B Plat Border   ( Note:  You may have to “right click” and “save link as…” for this document)  Surveyor Sample Legal Plat   Right-of-Way  Central San reviews improvement plans to determine if there is any potential conflict with existing right-of-way and Central San easements on the property. The local building department typically requires Central San’s review prior to their first review. The plans must accurately depict right-of-way and Central San’s easements and the Applicant’s existing and proposed improvements. Encroachments are not permissible in right-of-way or Central San easements. Furthermore, Central San does not maintain the surfaces of rights-of-way or easements. For example, Central San does not maintain roads, streets, trails, paths, slopes, fences, or vegetation, except when required to maintain and service Central San facilities.   Read more Pod June 6, 2023 Standard Specifications Click here to see the Standard Specifications for Design and Construction Read more Footer link March 30, 2018 Footer Top Bar (always first) Contact Us 5019 Imhoff Place Martinez, California 94553 Join Our Mailing List: * Read more Footer link February 13, 2018 Home Read more Footer link February 13, 2018 Contact Read more Footer link February 13, 2018 Tours Read more Footer link February 13, 2018 Report a Problem Read more Footer link February 13, 2018 Careers Read more Social link November 18, 2019 Instagram Read more Social link February 13, 2018 Facebook Read more Social link February 13, 2018 YouTube Read more Social link August 13, 2025 Nextdoor Read more Log in E-mail or username: * Password: * Remember me Request new password Commands Support portal Log in Footer Top Bar (always first) - Central Contra Costa Sanitary District Skip to main content Skip to site navigation Central Contra Costa Sanitary District Central San Search Menu More options Residents Pollution Prevention Sewer Overflow Prevention Construction Zones Emergency Preparedness Businesses Environmental Compliance Pollution Prevention Programs Doing Business with Central San Construction Permits Permit Counter Operations Contractor Requirements Standard Specifications & Approved Materials Mainline Extensions Easements & Right-of-Way Permit FAQs Fees Rates & Charges Financing Programs Education Learn Central San Academy Treatment Plant Tours Speakers Bureau Central San 80th Open House Water and Wastewater Plant Operator Training Publications Videos Home & Garden Household Chemicals Talksics Toastmasters About COVID 19 Response District Boundary/Divisions Who We Are Awards and Achievements Board of Directors Management Careers Facilities Sewer System Public Notices & Public Review Documents Plans & Reports Financial Information Contact Us Footer Top Bar (always first) Footer link March 30, 2018 Contact Us 5019 Imhoff Place Martinez, California 94553 Join Our Mailing List: * Share this page Share on Facebook Share on Twitter Share on LinkedIn This item appears in Back Footer link March 30, 2018 Footer Top Bar (always first) Contact Us 5019 Imhoff Place Martinez, California 94553 Join Our Mailing List: * Read more Footer link February 13, 2018 Home Read more Footer link February 13, 2018 Contact Read more Footer link February 13, 2018 Tours Read more Footer link February 13, 2018 Report a Problem Read more Footer link February 13, 2018 Careers Read more Log in E-mail or username: * Password: * Remember me Request new password Commands Support portal Log in Residents Pollution Prevention - Central Contra Costa Sanitary District Skip to main content Skip to site navigation Central Contra Costa Sanitary District Central San Search Menu More options Residents Pollution Prevention Sewer Overflow Prevention Construction Zones Emergency Preparedness Businesses Environmental Compliance Pollution Prevention Programs Doing Business with Central San Construction Permits Permit Counter Operations Contractor Requirements Standard Specifications & Approved Materials Mainline Extensions Easements & Right-of-Way Permit FAQs Fees Rates & Charges Financing Programs Education Learn Central San Academy Treatment Plant Tours Speakers Bureau Central San 80th Open House Water and Wastewater Plant Operator Training Publications Videos Home & Garden Household Chemicals Talksics Toastmasters About COVID 19 Response District Boundary/Divisions Who We Are Awards and Achievements Board of Directors Management Careers Facilities Sewer System Public Notices & Public Review Documents Plans & Reports Financial Information Contact Us Social link November 18, 2019 Instagram Read more Social link February 13, 2018 Facebook Read more Social link February 13, 2018 YouTube Read more Social link August 13, 2025 Nextdoor Read more Residents Pollution Prevention Sewer Overflow Prevention Construction Zones Solar Emergency Preparedness Residents Pollution Prevention Overview November 16, 2017 Household Hazardous Waste Collection Facility Hazardous waste generated by residents and businesses can reach our waterways through runoff, sanitary sewers, storm drains, landfills, and can pollute our local water environment.

In some instances, however, the residence is lower than the elevation of the public sewer. When this situation exists, it is necessary for the property owner to install and maintain a residential sewage pump to lift the sewage from the residence up to the public sewer.
