The sewer collection activity is primarily responsible for maintaining an estimated 310 miles of sanitary sewer system and 31,000 residential and commercial sewer lateral connections. This program also performs through contract, root foaming, manhole rehabilitation, infiltration control, spot repairs and cleaning of larger trunk lines. Employees in this activity provide a comprehensive program of televising, archiving and benchmarking the overall condition of the sewer system infrastructure. Information will be used to establish maintenance requirements, the need for repairs and development of Capital Improvement Projects. Personnel also assist in staffing an alternative work shift and 24-hour Stand-by system that responds to emergency after hour calls for service.
City of Antioch Sewer System Management Plan (SSMP)
Pursuant to State Water Resources Control Board Order 2006-0003, Statewide General Discharge Requirements of Sanitary Sewer Systems the City of Antioch has developed and implemented a Sewer System Management Plan (SSMP). The goal of the SSMP is to minimize the frequency and severity of sanitary sewer overflows. The SSMP covers the management, planning, design, and operation and maintenance of the agency’s sanitary sewer system. The development process began in January 2007 and was completed April 2009 and adopted by Council on April 28, 2009. (SSMP Staff Report).
The SSMP is available for review at the Department of Public Works, 1201 West 4th Street, during normal business hours (Department Home Page) . Interested parties can contact Jeff Cook at (925) 779-6962 or firstname.lastname@example.org for additional information.
Sanitary Sewer System Performance
Effective August 2007 the City began reporting SSO's electronically to the California Integrated Water Quality System (CIWQS). The electronic SSO data, as well as information regarding regulatory actions, is available at:
Protect Your Property from Sewage Overflow with an Overflow Protection Device.
Wherever a sewer system exists, so does the potential for overflows. Most sewage overflows occur when sewer lines are blocked by roots, grease, debris, or structural failure. Raw sewage can then backup into your home or business, resulting in property damage and environmental problems.
When you see or experience a sewage backup, report it immediately to the City of Antioch Public Works Department 925-779-6950 (after hours 925-778-2441).
Our crew will respond within minutes, locate the blockage and determine if the problem is within the public sewer. If it is, the crew will clear the blockage. You as a property owner are responsible for your plumbing, if the City determines that the problem is in the property owner’s sewer connecting your plumbing to the public sewer, it is your responsibility, and the City cannot remove the blockage or make repairs, you or a licensed plumber will need to make the necessary repairs. (City Sewer Lateral Policy).
Our storm water collections maintenance program is responsible for maintaining, in a safe and serviceable condition, all catch basins, storm drains, channels, detention basins, creeks, culverts and concrete lined “V” ditches in open space, that handle storm water run-off in the City of Antioch’s jurisdiction. Personnel assigned to this activity remove debris, illegally dumped trash, perform weed abatement activities including chemical vegetation control, stencil storm drain inlets, perform work associated with flooding, erosion control, channel beautification, arrange for and monitor contract maintenance work, interact with regulatory agencies responsible for protecting water quality and wildlife when performing required maintenance activities and developing projects which require permits from the Department of Fish and Wildlife, the Central Valley Regional Water Quality Control Board, and the Army Corps of Engineers.
