DESCRIPTION 

The City of Thousand Oaks is seeking a hands-on and technically proficient Wastewater Treatment Plant Maintenance Supervisor to support operations at the Hill Canyon Treatment Plant (HCTP), a 24-hour, Class V advanced tertiary wastewater treatment facility with a 14-million-gallon-per-day capacity that treats an average of eight million gallons of wastewater daily from domestic commercial, and industrial sources. HCTP employs a wide range of sophisticated technologies, including a SCADA system, complex mechanical process equipment, analytical instrumentation and meters, industrial electronic control systems, and power distribution infrastructure.  

The Maintenance Supervisor oversees the maintenance of this diverse and critical equipment, including on-site power generation systems such as biogas-fueled cogeneration and photovoltaic solar array that offsets the facility’s energy use.

This role requires strong leadership, sound technical judgment, and the ability to manage shifting priorities in a highly regulated, continuously operating environment, while ensuring safe, reliable, and compliant plant operations.
