About the job
Reporting to the Process Engineering team, the Water & Wastewater Process Engineering Intern provides hands‑on technical, laboratory, and field support across a variety of water and wastewater treatment projects. In this role, you will contribute to testing, data analysis, and process evaluation efforts that help optimize thickening, dewatering, and separation system performance for municipal and industrial applications.

This internship offers exposure to real‑world treatment operations, bench‑scale and pilot‑scale testing, and cross‑functional collaboration with engineers, operators, and field staff. You will play an active role in sample analysis, process troubleshooting, data interpretation, and the development of tools that improve lab and pilot‑unit workflows.

This is a role based in Houston, TX.

As a part of the team, you will:

• Support technical and laboratory activities by preparing, testing, and analyzing samples from municipal and industrial facilities.

• Assist with water and wastewater testing to help estimate thickening and dewatering performance.

• Participate in bench-scale and pilot-scale trials, supporting ongoing experiments and documenting results.

• Maintain accurate lab records and contribute to the creation of technical reports.

• Develop a planning and scheduling tool to streamline lab sample management.

• Work with process engineers to evaluate separation system performance using operational data, lab results, and field observations.

• Support field activities at treatment plants or pilot facilities, gaining hands‑on experience with equipment and operations.

• Assist in troubleshooting process issues by monitoring system parameters and collecting operational data.

• Develop a tracking system to improve reservation and management of pilot/demo units.

• Analyze experimental data and prepare technical summaries for engineering review.

• Help create reports and presentations that support process optimization and equipment selection.

• Present your internship findings to engineering and management teams at the conclusion of the program.

What you know:

You are a rising college junior or senior with preference for students pursuing coursework in engineering, environmental science, chemistry, biology, data analytics, or related fields and you bring:

• Strong analytical and problem‑solving skills with the ability to interpret experimental and operational data.

• Interest in water, wastewater, or environmental processes and a desire to gain hands‑on experience.

• Attention to detail in testing, documentation, and data recording.

• Clear written and verbal communication skills to support reporting and team collaboration.
