Thank you for partnering with us to protect public health and the environment.
Every time you flush, shower, or run the dishwasher… that wastewater travels through a network of more than 350 miles of underground pipes and 23 pump stations to one of WES’ five treatment facilities, where it is cleaned and safely returned to our rivers.
Every time it rains… WES’ stormwater system collects and directs the rainwater from streets, roofs, and driveways to prevent flooding, protect local streams and rivers, and ensure clean water for fish, wildlife, and the community.
For about $2.17 per day, Clackamas Water Environment Services (WES) cleans approximately 7 billion gallons of wastewater each year and manages stormwater across the entire service area.
As a WES customer, you’re part of a community of nearly 200,000 people who share these systems, and who make it possible to keep them running reliably every single day.
Keeping WES’ systems working reliably every day requires ongoing investment
Much of WES’ infrastructure was built 40 to 50 years ago. Keeping it in good shape takes ongoing, proactive investment, which your rates help support.
WES’ fiscal year 2026-27 budget invests $66.2 million in construction projects to maintain aging infrastructure and expand system capacity to support our growing community.
WES plans ahead to make these investments while keeping rate adjustments steady, predictable, and as low as possible. In the past five years, WES’ annual rate adjustments have averaged between 1.6% and 4.4%, lower than the regional inflation rate of 4.5% during the same time.

Operations and Maintenance 62%

Debt Service 11%

WES is committed to being transparent and accountable with how every dollar is spent.
Proposed Rate Changes
Starting July 1, 2026, the average monthly household bill is proposed to increase by $1.25 ($15 annually).
This adjustment reflects the ongoing cost of delivering safe, reliable services and continuing to invest in the infrastructure our community depends on.
| Service | Proposed Rate | Existing Rate | Change |
|---|---|---|---|
| Sanitary Sewer 1 | $ 55.20 | $ 54.40 | $ 0.80 (1.5%) |
| Surface Water | $ 10.00 | $ 9.55 | $ 0.45 (4.7%) |
| Total Monthly Bill | $ 65.20 | $ 63.95 | $ 1.25 (2.0%) |
1 Sanitary Sewer rate reflects retail rate, which includes wastewater treatment, local collection, and legacy debt components.
How WES’ rates are set
Clackamas Water Environment Services is funded almost entirely by the rates and fees paid by our customers and the communities we serve, which means rates must be sufficient to cover all costs necessary to deliver essential services, including treatment operations, system maintenance, infrastructure investment, and long-term capital financing.
WES’ rates are set at the lowest level needed to meet those obligations. Each year, the Clackamas County Board of Commissioners, serving as WES' Board of Directors, adopts WES' rates as part of the public budget process.
Participate in the Budget and Rate-Setting Process
Your input matters. WES’ Board of Directors will review and consider the budget and rates for approval on June 17, 2026.

How do WES’ rates compare regionally?
WES’ current monthly rates for single-family homes are lower than the average rates in nearby areas that offer similar sewer and surface water services.
Thanks to careful long-term planning, the proposed rates for 2026-27 are set to stay below the regional average, while still covering capital investments and rising operating costs.
