Wastewater Treatment Mechanics perform a variety of skilled tasks in maintaining, overhauling and assembling mechanical equipment and auxiliaries associated with large diesel engines, pumps, compressors, barscreens, collectors, clarifiers, centrifuges, conveyors, heat exchangers,and other equipment found in a wastewater treatment plant or a wastewater collection system. Tasks include the more difficult and skilled mechanical work required at a wastewater treatment plant and sewage lift stations.

Employees perform a variety of mechanical and building trade tasks. Although performance of skilled work is required in many of the repairs made, skills required in any one type of trade are usually less than would be required of a journeyman in that field. Work differs between positions, but in most cases primary emphasis is upon mechanical ability and some electrical skills. Work is performed independently, but frequently is inspected upon completion.

The City maintains and operates 4 wastewater treatment plants, 61 sewage lift stations, and 2 sewage main pump stations. This is work that may include some supervisory duties.
