On May 2, 2006, the State Water Resources Control Board (SWRCB) adopted Water Quality Ordinance Order No. 2006-0003, which required all public wastewater collection agencies in California, with a wastewater collection system greater than one mile in length, to be regulated under the Statewide General Waste Discharge Requirement (GWDR). The GWDR requires public wastewater agencies to develop a Sewer System Management Plan (SSMP) for their wastewater collection systems. Although this management plan is solely for internal use by city staff, the existing SSMP is available for public view and comment. Please direct comments to engineering@cityofdixon.us.
