Expand your career horizons and create a sustainable future in a paid internship

Are you a college or graduate student considering careers that build a sustainable future? King County Wastewater Treatment Division has internship opportunities for you! WTD offers paid summer internships in a wide range of fields that design, build, and operate our regional clean water system. 

WTD’s college and graduate interns create real value for our projects, programs, and agency while getting real world job experience, networking, and learning about water systems. Summer interns join a group of their peers to take training, develop job skills, and complete their own projects.

Interns get exposure to careers and opportunities they might not have imagined before. Participants have used their internships to acquire jobs at their universities, in King County, and elsewhere.
