MISSION Our mission is to make Vallejo a healthy place to live and work. We do this by keeping the city's wastewater and stormwater free from pollution. We employ around 90 people who work in the following areas: wastewater treatment, maintenance (mechanics, IT and electricians), field operations, environmental services, safety and risk, finance, engineering, and administration. We manage Vallejo's treatment plant and more than 40 pump stations, and maintain hundreds of miles of sewer and stormwater pipes.
