Waste Water Treatment Plant Secondary Process Upgrade ProjectThe City of Auburn is proposing a number of secondary process upgrades to the City’s Waste Water Treatment Plant (WWTP) to improve performance, add process redundancy, and comply with expected new permit limitations. The WWTP Secondary Process Upgrade project would construct a new oxidation ditch and associated facilities, including a new electrical building.
The new oxidation ditch would be located within an existing treatment pond. The proposed project would not increase the permitted amount of effluent discharged from the plant (1.67 million gallons per day average dry weather flow). Construction would begin in the summer of 2016. Available documents for the project include the Initial Study and Mitigated Negative Declaration (IS/MND) and the Notice of Intent (NOI).
User fees are based on the City of Auburn Wastewater System Financial Plan dated April 2007. All accounts shall be assessed a monthly charge at a flat rate based on an equivalent single-family residence (ESU).
Sewer System Management Plan
In May 2006, the California State Water Resources Control Board (SWRCB) adopted Order No. 2006-0003-DWQ – Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. The Order applies to all public collection system agencies California that own or operate a collection system containing a mile or more of pipe or sewer lines, which convey untreated wastewater to a publicly owned treatment facility. The Order requires each agency to prepare a Sewer System Management Plan (SSMP).
The City of Auburn (City) has completed all 11 elements of the SSMP as listed in the original Order. The purpose of this document is to show the “effectiveness of the SSMP and the Enrollee’s compliance with the SSMP requirements” and “identification of any deficiencies in the SSMP and steps to correct them”.
Sewer Connection Fees
- The Sewer Connection fee is charged on a per equivalent dwelling unit (EDU) basis.
- Effective July 1, 2018: $8,615 per Sewer Unit
- Sewer Connection Fees are collected with the issuance of a building permit or at a request to connect to the sewer system.
- For more information on fees, view our rate charts. To find out how to request sewer service or pay your fees, visit the customer service counter.
- The Sewer Connection Fee will be automatically adjusted each July 1 in proportion to the change in the Construction Cost Index for the San Francisco Bay Area most recently published in the Engineering News-Record published by McGraw Hill. No action of the City Council is required to cause this annual adjustment.
Live Sewer Smart: Prevent Costly & Messy Sewer Back-UpsDo you know that dumping your cooking, fats, oils and grease (FOG) down the sink eventually leads to a thick build up in your home's sewer system, which can clog your sewer pipes?
Learn how to "live sewer smart" by collecting your FOG in a container that can be sealed. For information regarding properly disposal of FOG and easy ways to dispose of your FOG visit the Live Sewer Smart website.
Wastewater Treatment & CollectionThe City of Auburn owns its own wastewater treatment and collection system, which serves the municipal boundaries of the city. Operation and maintenance of the wastewater treatment and collection system is performed under contract by Operations Management International (OMI). The Auburn Municipal Airport and Industrial Park are served by Placer County Sewer Maintenance District (SMD) No. 1.
The city treatment plant is located west of the city in the Ophir area. The plant is permitted to discharge its treated effluent into Auburn Ravine Creek to a maximum flow of 1.65 million gallons per day. The effluent is treated to what is commonly referred to as tertiary treatment, which is the highest level of treatment required by the State of California.
The city also maintains over 85 miles of wastewater collection lines and over 1,500 manholes throughout the city. This network of pipes collects sewage from residences and businesses within the city and transports it to the treatment plant. The City also maintains 11 sewer lift stations.
Regional Wastewater Treatment & Conveyance SystemThe City of Auburn is a member of the Placer-Nevada Wastewater Authority (PNWA), a Joint Powers Agency (JPA), established in 1999 to develop a regional wastewater treatment and conveyance system. The charge of the PNWA is to regionalize the wastewater treatment of 6 jurisdictions in western Placer County. In so doing, 5 smaller and older treatment plants will be closed with their wastewater flows being sent to a larger modern facility located in Lincoln. PNWA has to date received approximately $2 million in funding from federal sources to conduct the necessary studies and design work for this project.
Emergency Contact InformationIf you should ever observe wastewater backing up in your area or flowing out of a manhole in the street, please notify the plant operators immediately at 530-889-0624.

Dental Amalgam Wastewater Sources and Management
EPA promulgated pretreatment standards in 2017 to reduce discharges of mercury from dental offices into publicly owned treatment works (POTWs). The Dental Office Category regulation is codified at 40 CFR Part 441.
Dental offices discharge mercury present in amalgam used for fillings. Amalgam separators are a practical, affordable and readily available technology for capturing mercury and other metals before they are discharged into sewers that drain to POTWs. Once captured by a separator, mercury can be recycled.
EPA expects compliance with this final rule will annually reduce the discharge of mercury by 5.1 tons as well as 5.3 tons of other metals found in waste dental amalgam to POTWs.
Dental offices that place or remove amalgam must operate and maintain an amalgam separator and must not discharge scrap amalgam or use certain kinds of line cleaners. Existing and new sources must submit a one-time compliance report to their local wastewater utility.
Dental facilities must submit a one-time compliance report as required by the Effluent Limitations Guidelines and Standards for the Dental Office Category (“Dental Amalgam Rule”). Some dental facilities are not required to submit a one-time compliance report. See the applicability section (§ 441.10) to determine if your facility is required to submit a one-time compliance report.
