Wastewater Operations and Maintenance

What We Do

The Plant Operations and Maintenance Section of the Wastewater Division is responsible for the treatment facilities and lift stations. Wastewater treatment plant operators monitor the treatment plant 24 hours a day, 7 days a week to ensure regulatory compliance and maintain process control. The wastewater treatment plant operators are certified Grades I through V, as required by the California Water Resources Control Board, Office of Operator Certification and the maintenance staff are CWEA certified technicians. The maintenance staff is responsible for performing preventative maintenance tasks keeping all of the equipment in excellent working condition. This allows the operations staff to make sure all processes run smoothly. Maintenance staff works closely with the operations staff to resolve issues that may arise as to keep disruptions in the process to a minimum. The treatment process and liftstations contain confined spaces and hazardous chemicals. All of the operations and maintenance staff are trained in confined space entry, and are First Responders that can assist with an emergency involving hazardous chemical releases.



Wastewater Treatment Process

Wastewater (liquid waste) from flushing the toilet, bathing, washing sinks and general cleaning goes down the drain and into a pipe, which joins a larger sewer pipe under the road. The larger pipe also joins a major pipe that leads to the treatment facility.
