WASTEWATER TREATMENT PLANT SUPERVISOR
$6,845 - $8,322
WASTEWATER TREATMENT PLANT SUPERINTENDENT
$7,485 - $9,102
One position, flexible allocation depending on qualifications.
DEFINITION
Under general direction of the Public Works Director, to independently plan, schedule, supervise and administer the operation and maintenance of the wastewater treatment plant, wastewater treatment and effluent disposal processes, and sludge treatment, handling and disposal; to monitor industrial wastewater flows and their effects on treatment; and to supervise and coordinate plant personnel. Incumbent serves as the principal staff technical resource to the Public Works Director in matters related to wastewater treatment plant operations and exercises independent technical judgment within established policies, approved budgets and delegated authority. The position identifies problems early, implements corrective action within its authority, and presents findings and actionable recommendations to the Director. Wastewater collection system management is excluded from this position.
DISTINGUISHING CHARACTERISTICS
Expectations at both levels
This is a single position filled at either the Supervisor or Superintendent level based on qualifications and demonstrated management experience. Both levels report directly to the Public Works Director and provide independent day-to-day technical and operational leadership of the wastewater treatment plant. The assignment is primarily supervision and technical oversight, with hands-on operating, sampling or maintenance work performed as needed. The Public Works Director provides general direction, establishes department priorities, and addresses funding, policy and organizational matters. The incumbent is accountable for plant performance, assigned staff, timely compliance activities and follow-through, and is expected to resolve routine technical matters without detailed direction from the Director. The incumbent is expected to provide ongoing plant operating leadership without reliance on a standing operations consultant. Specialized engineering, regulatory and other professional assistance is coordinated as needed within approved resources and authority.
Wastewater Treatment Plant Supervisor
Supervises daily treatment processes, maintenance, sampling, operating records and assigned personnel; implements operating procedures, compliance requirements and approved improvements; independently resolves operating problems within delegated authority; and identifies needs for specialized assistance, additional resources or Director decisions. Contributes technical information and recommendations to budgets and capital planning.
Wastewater Treatment Plant Superintendent
Performs the same core plant leadership responsibilities as the Supervisor and is distinguished by demonstrated experience and greater independence in managing complex regulatory matters, developing programs, evaluating long-range needs and leading plant improvement projects. Integrates operating, compliance, staffing, energy and financial considerations into recommendations to the Director and provides broader management of complex assignments with less outside assistance. Both levels are responsible for compliance follow-through, industrial pretreatment, budget participation and technical project coordination; appointment at the Superintendent level reflects the experience and judgment brought to these responsibilities.
