Wastewater Engineer


Design or oversee projects involving provision of potable water, disposal of wastewater and sewage, or prevention of flood-related damage. Prepare environmental documentation for water resources, regulatory program compliance, data management and analysis, and field work. Perform hydraulic modeling and pipeline design.

Water and wastewater treatment specialists oversee an entire process or system of machines, often through the use of control boards, to transfer or treat water or wastewater. Core tasks include:

  • Adding chemicals such as ammonia, chlorine, or lime to disinfect and deodorize water
  • Inspecting equipment or monitoring operating conditions, meters, and gauges to determine load requirements and detect malfunctions.
  • Collecting and testing water and wastewater samples, using test equipment and color analysis standards
  • Recording operational data, or meter and gauge readings on specified forms
  • Operating and adjusting controls on equipment to purify and clarify water, and process or dispose of wastewater
  • Understanding local, state, and federal rules and regulations regarding water treatment and wastewater disposal

Duties and Responsibilities.

1) Develop plans for new water resources or water efficiency programs.

2) Design water distribution systems for potable or non-potable water.

3) Design sludge treatment plants.

4) Provide technical support on water resource or treatment issues to government agencies.

5) Conduct water quality studies to identify and characterize water pollutant sources.

6) Identify design alternatives for the development of new water resources.

7) Gather and analyze water use data to forecast water demand.

8) Write technical reports or publications related to water resources development or water use efficiency.

9) Analyze and recommend sludge treatment or disposal methods.

10) Design water storage tanks or other water storage facilities.

11) Design water run-off collection networks, water supply channels, or water supply system networks.

12) Design water or wastewater lift stations, including water wells.

13) Review and critique proposals, plans, or designs related to water or wastewater treatment systems.

14) Provide technical direction or supervision to junior engineers, engineering or computer-aided design (CAD) technicians, or other technical personnel.


15) Design or select equipment for use in wastewater processing to ensure compliance with government standards.

16) Perform mathematical modeling of underground or surface water resources, such as floodplains, ocean coastlines, streams, rivers, or wetlands.

17) Perform hydrological analyses, using three-dimensional simulation software, to model the movement of water or forecast the dispersion of chemical pollutants in the water supply.

18) Perform hydraulic analyses of water supply systems or water distribution networks to model flow characteristics, test for pressure losses, or to identify opportunities to mitigate risks and improve operational efficiency.

19) Oversee the construction of decentralized or on-site wastewater treatment systems, including reclaimed water facilities.

20) Conduct feasibility studies for the construction of facilities, such as water supply systems, run-off collection networks, water and wastewater treatment plants, or wastewater collection systems.

21) Conduct environmental impact studies related to water and wastewater collection, treatment, or distribution.

22) Conduct cost-benefit analyses for the construction of water supply systems, run-off collection networks, water and wastewater treatment plants, or wastewater collection systems.

23) Analyze the efficiency of water delivery structures, such as dams, tainter gates, canals, pipes, penstocks, or cofferdams.

24) Analyze storm water or floodplain drainage systems to control erosion, stabilize river banks, repair channel streams, or design bridges.

25) Analyze and recommend chemical, biological, or other wastewater treatment methods to prepare water for industrial or domestic use.

26) Design pumping systems, pumping stations, pipelines, force mains, or sewers for the collection of wastewater.

27) Design domestic or industrial water or wastewater treatment plants, including advanced facilities with sequencing batch reactors (SBR), membranes, lift stations, head works, surge overflow basins, ultraviolet disinfection systems, aerobic digesters, sludge lagoons, or control buildings.
