What is wastewater pretreatment?
Wastewater pretreatment is the reduction, elimination or alteration of pollutants prior to discharge into the wastewater system.
It ensures wastewater discharged to our wastewater collection system meets local, state and federal discharge limits. Pretreatment protects the health and safety of the public and the environment, as well as the wastewater system and personnel.
How is the pretreatment program implemented?
The pretreatment program is implemented through the Wastewater Discharge permit process.

When a stoppage occurs, you should contact the City immediately at (805) 797-7598; this emergency number is monitored 24 hours a day, 7 days a week, including holidays.
Wastewater personnel will come out to the site and assess the stoppage to determine if the obstruction is on the City’s side of the sewer line or the homeowner’s sewer service line. The City will clear any blockage that occurs in the City’s sewer main. Customers are responsible for blockages that occur in their private sewer lateral and connection.
You can set up a maintenance schedule to include annual cleaning of your private sewer lateral with a private service company, or you may need to have your service line videotaped to check its condition.
Do NOT flush disposable diapers and baby wipes as they will clog your sewer line. In addition, never pour grease or gummy substances down garbage disposals, toilets, or floor drains. Flammable liquids, i.e. used motor oil, gasoline, paint thinner, etc., should never be poured into your sewer line as they can cause a fire hazard or create a harmful coating on your sewer pipe. Never flush feminine hygiene products, pencils, pins, hypodermic needles, broken glass or other foreign objects that can lodge in your sewer service line and cause a sewer back-up.

The Wastewater Division has implemented a preventative maintenance program of sewer cleaning and condition assessment of the entire sewer collection system. The periodic cleaning and video taping of the sewer lines in your neighborhood can reduce the risk of any grease or root buildup which reduces the likelihood of sewer back-ups and/or sanitary sewer overflows. The City utilizes three sewer cleaning vehicles and one video truck with closed-circuit television (CCTV).
