PLEASE READ THIS BULLETIN IN ITS ENTIRETY

THE POSITION
This recruitment is being conducted to fill three full-time vacancies. The list established by this recruitment may be used to fill future full-time, part-time, limited term, and temporary vacancies for up to one year.

Why Join the City of Vallejo Water Department
The City of Vallejo Water Department is staffed by dedicated professionals with deep technical expertise and a strong commitment to public service. Our team values integrity, accountability, and collaboration.
We cultivate a supportive, growth-oriented environment where employees are encouraged to expand their skills, share innovative ideas, and take ownership of their work. With a strong emphasis on training, professional development, and sustainability, this is more than just a workplace—it’s a place where your contributions have a lasting impact and where teamwork drives success.

The Ideal Candidate
The ideal candidate for the position of Senior Water Treatment Plant Operator will have sufficient working knowledge and progressively responsible experience working in a T3 system (or higher) drinking water treatment facility, comparable to Vallejo's surface-water treatment processes.

THE DEPARTMENT
The Vallejo Water Department is a dynamic organization engaged in growth and positive change for the benefit of our customers and community. The Department provides potable water to 121,000 customers through a highly complex system including multiple raw water sources, three treatment plants, a Sludge Dewatering Facility, 600 miles of distribution pipes, 8 pressure zones, 27 pump stations, and 37,000 service connections. Vallejo Water is a Treatment-5/Distribution-5system. In 2017, Vallejo water services transitioned from a division of Public Works to a standalone Water Department reporting directly to the City Manager. This change gives drinking water-related operations and issues greater visibility and strategic direction for the benefit of rate-payers. The Water Department's strategic goals include: infrastructure reliability, public trust, sustainability, organizational performance, and financial viability.
The Water Department has six Divisions: Water Treatment, Engineering, Distribution, Water Quality, Watershed and Facilities Management, and Administration/Conservation.

THE CITY OF VALLEJO
The City of Vallejo is located in Solano County and has a population of approximately 121,000 residents. Vallejo is a rapidly changing, highly diverse community located midway between the cities of San Francisco and Sacramento. It is a friendly, active waterfront community that attracts innovative, hardworking people and takes great pride in its 148-year history and maritime heritage. Residents of Vallejo are situated to take advantage of the best of what the area has to offer. Golf, museums, performing arts, boutique shopping, brewpubs and a wide selection of restaurants are all available in Vallejo. Residents and visitors alike enjoy Vallejo’s delightful historical downtown area, weekly downtown farmer’s market, and beautifully restored Victorian homes and business facades. Vallejo is also home to Six Flags Discovery Kingdom, one of America’s only combination wildlife, oceanarium and theme parks.
