Clackamas Water Environment Services' (WES) adopted budget for fiscal year 2025-26 totals $247.6 million. The budget supports WES' mission to protect public health, produce clean water, manage stormwater, and recover renewable resources for nearly 200,000 people across our service area. Major investments include $51.5 million in critical infrastructure projects to maintain safe, reliable service and support future growth.
To fund increasing operating and maintenance costs and continue investing in system reliability, modest rate adjustments have been approved. For most residential customers, the combined monthly wastewater and surface water bill is expected to increase by approximately $1.25 per month (about 2%), keeping WES' rates below the regional average.
The WES Budget Committee reviewed and approved the proposed budget on May 27, 2025, and the Clackamas County Board of Commissioners (serving as the governing body of WES) adopted the budget and updated rates on June 18, 2025 following a public hearing.
