The Wastewater Division operates and maintains the City's 5 wastewater pump stations and approximately 32 miles of underground wastewater collection system piping. A majority of the collection system is 50 years old or greater. The system has over 5,000 service connections and 700 manholes. The primary function of the Wastewater Division is to protect the health and safety of the public, as well as to protect the environment.
Wastewater staff operates state-of-the-art equipment including a closed circuit TV pipeline inspection system, in ground (no excavation) pipeline repair equipment, high-pressure pipeline cleaning equipment, vacuum trucks, and specialized safety equipment.
Staff utilizes the equipment to perform various preventative maintenance activities in addition to performing capital repair and rehabilitation projects.
Pumping stations are equipped with automated electronic controls that minimize electrical usage, provide alarm systems to alert staff to problems, and ensure wastewater flows to the treatment plant without service interruption.
The City's system transports sewer flows from the Naval Base Ventura County Construction Battalion Center, Oxnard Harbor District and the City of Port Hueneme. Sewer flows total approximately 2 million gallons per day. These flows are transported through a series of pumped force mains and gravity lines ranging from 6 inches to 36 inches in diameter. The collected wastewater flows to the regional wastewater treatment facility located in, and operated by, the City of Oxnard. Once there it is treated, tested for compliance and discharged into the Pacific Ocean through an outfall that extends 5 miles from the coastline.
