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.

DISTINGUISHING CHARACTERISTICS
This is the advanced journey level classification in the Water Treatment Plant Operator series. Employees in this classification have successfully obtained their Grade T4 and demonstrated their ability to perform and lead others in the full range of responsibilities involved in the operation and maintenance of a serviceable water supply through the City's transmission, distribution facilities, water treatment plants and sludge de-watering facility, without direction. Incumbents function with a high degree of autonomy to apply advanced concepts and expertise in specific areas to resolve issues/problems that are often of a unique nature without precedent and/or structure. Assignments may include formulating strategies and making recommendations for improved processes and allocation of resources. This classification is distinguished from Water Treatment Plant Supervisor in that the latter is a first-line supervisory classification responsible for the direct supervision and development of assigned staff, planning, goal implementation, policy development, assisting with budget preparation, as well as managing the day-to-day operations of an assigned treatment plant.
As a condition of continued employment with the City of Vallejo in the classification of Senior Water Treatment Plant Operator, incumbents are required to maintain a Grade T4 Water Treatment Plant Operator certification by the California State Water Resources Control Board (SWRCB).
