What We Do
The Bureau of Environmental Services (BES) is one of the largest bureaus in the City of Portland. We are responsible for planning, operating, maintaining, and improving all aspects of the city’s wastewater and stormwater systems. We also restore streams and watersheds to protect water quality, public health, and the environment.
Ratepayers fund Environmental Services work with most of our funding coming from monthly combined sewer and stormwater bills. Environmental Services also receives funding from system development charges, connection charges, and various permit fees.
We have completed major improvements in recent decades, such as the Big Pipe Project that protects the Willamette River and Columbia Slough from combined sewer overflows. But we have also re-imagined ourselves, shifting from a traditional sewer utility to a service-oriented bureau that implements innovative, cost-effective, green solutions like trees, green street planters, and restored natural areas to help protect water quality and public health.
Together with Portland residents and businesses, we are adding nature to the City to improve public health, meet our climate challenge, and benefit all Portlanders.
In 2017, we charted a new direction for Environmental Services. Our 10-year strategic plan:
- Will help us work together as a unified organization delivering high-quality services to the community.
- Reinforces our commitment to cost-effective, green infrastructure solutions.
- Includes our commitment to equity, diversity, and inclusion in how we work together and how we deliver services.
- Puts us on a path to becoming a fully sustainable utility in 10 years to meet the needs of current customers and future generations.

Our Equity Commitment
Our Work Culture
Environmental Services intentionally builds and nurtures a safe and inclusive environment in which employees are able to bring their true selves to work.
We are committed to engaging with our community in an accessible and thoughtful way to deliver services that benefit all Portlanders, especially Black, Indigenous, and other people of color (BIPOC) who have experienced historical inequities. Together with our BIPOC community partners, we commit to working proactively to correct those imbalances and put an end to systemic racism.
Every bureau employee is responsible for advancing equity in our workplace culture and service delivery.
