Tigard, OR Intern|Temporary
POSTED ON 4/18/2026
AVAILABLE BEFORE 5/4/2026

The Water and Engineering Technology Department is seeking an intern for its Research and Innovation Division. This position works with a team of engineers and scientists within Research and Innovation to research improvements to the design and operation of Clean Water Services (CWS) water resource recovery facilities. The selected candidate will work primarily in the treatment facilities’ on-site laboratories, where they will develop practical skills and gain knowledge of wastewater treatment processes. In particular, the selected candidate will be tasked with supporting ongoing research projects by performing sampling, running routine tests, entering data, and assisting in sample and data analysis. This position often includes field work which can include repetitive heavy lifting of sample containers and standing or walking for long periods of time.

Examples of research tasks include:

  • Conducting benchtop tests to measure
    • The rate of biological phosphorus uptake to monitor the stability of full-scale nutrient removal processes
    • Biogas generation potential to monitor the health of full-scale anaerobic digesters
    • Nitrification rate testing to determine the inhibitory effects of industrial discharges
  • Assisting with settling column tests to quantify the settling characteristics of activated sludge
  • Performing particle size distribution measurements of tertiary solids

This intern position is an excellent opportunity to gain applied science and engineering experience working in a nationally recognized water resource recovery utility. You’ll get a hands-on understanding of how water resource recovery facilities function in day-to-day operation.
