About The Position

The Wastewater Treatment Mechanic performs skilled mechanical work in support of an Advanced Water Purification Facility (AWPF). This role is responsible for the installation, maintenance, overhaul, repair, and testing of mechanical equipment and systems used by the AWPF to achieve its treatment targets. This work directly affects the reliable operation of process pumps (including high-pressure and transfer pumps where applicable), motors and couplings, rotating equipment and mechanical drive components, valves and actuators, chemical feed equipment mechanical components, CIP/flush systems, and mechanical equipment serving membrane and advanced water treatment processes. Key duties include performing preventative and maintenance and mechanical inspections; troubleshooting and repairing rotating equipment and process machinery; aligning mechanical components; supporting start-ups, shutdowns, and planned outages; documenting work performed, equipment condition, and parts usage in the Computerized Maintenance Management System (CMMS) and required logs; coordinating troubleshooting with operations, electrical, and instrumentation & controls; and responding to mechanical failures affecting plant operations. The Wastewater Treatment Mechanic collaborates with operations, maintenance (including LASan facility O&M as applicable), engineering and manufacturer/vendor technicians to plan and execute work in support of continuous operations. Detailed Description: The mid-level mechanical assignment is supporting the reliable operation of an AWPF located within a wastewater treatment plant (WWTP). The AWPF is in one section of the WWTP, but access to the job site still requires driving through the WWTP. This role will be working with rotating machinery critical to the facility. The employee performs work on mechanical equipment that directly affects the plant’s process stability. The work includes troubleshooting equipment failures and coordinating maintenance activities with operations, electrical, and instrumentation & controls.
