WES Rates, Charges, and Fees

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.

Late Fees to Resume for Past-Due Bills Starting August 1, 2025

Beginning August 1, 2025, Clackamas Water Environment Services (WES) will resume assessing late fees on past-due utility bills. As the governing body of WES, the Board of County Commissioners has approved a new late fee structure: 2% of the past-due balance or $5.00, whichever is greater.

Late fees are intended to promote timely payments, reduce the cost of collections, and support the continued delivery of essential sanitary sewer and surface water services.

Avoiding Late Fees:

To avoid late fees, customers are encouraged to pay their monthly bill by the due date listed on their statement. WES offers a variety of tools to help manage your account, including online utility bill payments and paperless billing.  
Set up online payments and/or enroll in paperless billing.

Erosion Prevention and Sediment Control

Development activity can remove soil cover and increase the site’s susceptibility to erosion. This erosion, and the pollutants that can come from construction debris, can have an adverse impact on adjoining properties, the public storm drainage system and the health of our local streams. With the proper use of erosion prevention and sediment control (EPSC) measures, movement of pollutants and soil off of the site can be prevented and minimized

All development related activity within WES service districts is required to provide erosion prevention and sediment control (EPSC) measures as applicable. Sites which disturb 800 square feet or more are required to obtain Erosion Prevention and Sediment Control permit from WES. Also, all development activity within Clackamas County which disturbs 1-acre or greater is required to obtain a Department of Environmental Quality (DEQ) 1200-C Construction Stormwater (Erosion Control) Permit or a 1200-CN Permit.

Erosion Control Fees

Types of Erosion Prevention and Sediment Control Permits

Depending on the location, type and size of the development project, different EPSC permits and plans may be needed. The table below is a guide to help determine what is required. Following the table are descriptions of each of the permit types

Watershed Action Plans

Wastewater Facilities

Clean water is the biggest lifesaver in human history.

Thanks to advances in producing clean water over the last 200 years, life expectancy in the United States has more than doubled to 78.8 years. Most people take drinking water coming out of taps in our homes for granted. It’s also hard to imagine not being able to flush a toilet to carry wastewater away. The toilets and sewer systems we use today save millions of lives by preventing the spread of deadly diseases that come from dirty water.

At Clackamas Water Environment Services, we provide wastewater treatment services for more than 190,000 customers. 

Each year, our treatment facilities clean more than seven billion gallons of wastewater.  In the process, we convert materials that have long been considered “waste” into energy and natural fertilizer. We operate and maintain five resource recovery facilities, 23 pumping stations and more than 360 miles of pipes.

Septage Hauler Program

Our septage procedures are designed to comply with all applicable District, State and Federal regulations. Septage is regulated by our Rules and Regulations. The Tri-City Water Resource Recovery Facility (TCWRRF) is the only designated receiving facility in WES. Haulers that discharge septage at the TCWRRF are required to have a valid Septic Tank Waste Discharge Permit, which is issued for a three-year period.

Permit Application Process

To apply for a WES Septic Tank Waste Discharge Permit, septage haulers must complete and submit a completed Application for Permit form, current copy of DEQ license for sewage disposal, a $10,000 Surety Bond or Bond Continuation Certificate, a current copy of the DEQ Pumping Truck Inspection Report and three-year permit* fee. The application review process takes approximately 3–5 days after which the WES staff will then issue or deny a septage discharge permit.

Septic Tank Waste Discharge Permit application can be downloaded online. For additional information, contact WES Industrial Pretreatment Program at 503-557-2834.

* WES Septic Tank Waste Discharge Permit is a three (3) year permit, however, surety bonds, DEQ license, and DEQ Truck Inspection are issued annually. An updated copy of these items must be submitted to WES Septage Program annually.

Sources

WES accepts septage originating from within Clackamas, Multnomah and Washington Counties. City, State, and Federal regulations prohibit septage haulers from discharging industrial process wastes at the TCWRRF.

Septage loads are accepted Monday through Friday (except on holidays) between 6 a.m. and 3 p.m.

Biosolids Management

What are biosolids?

The wastewater treatment process separates solids and water, after which clean and disinfected water is discharged to a neighboring water body, the solids are carefully processed in anaerobic digesters to meet state and federal regulations. This further processing converts the dewatered solids into a useful, slow-release fertilizer, which contains a range of plant-essential nutrients such as nitrogen, phosphorus, sulfur, and potassium. Biosolids also contain small amounts of other important minerals such as magnesium, manganese, iron, zinc and calcium. Not usually found in commercial fertilizers.

WES currently recycles biosolids for beneficial use on dryland wheat farms in Eastern Oregon. Biosolids add valuable organic matter to the soil as a beneficial amendment. Organic matter provides a food source for soil microbes, increases the ability of the soil to hold water, and improves soil structure.

In addition, biosolids provide climate benefits. They capture and store carbon in the soil, and they reduce the need for commercial fertilizers, which are produced by a fossil fuel-intensive process.

Strengthened 82nd Drive Pedestrian Bridge Reopens

Owned and maintained by WES since 1998, the 82nd Drive Bridge connects Gladstone and Oregon City for walkers, joggers and bicyclists who use it to cross the Clackamas River. Built in the early 1920s,  the bridge was converted for pedestrian use after the construction of Interstate 205 was completed in the mid-1970s.

The bridge also carries sanitary sewer pipes and other important utility lines.

Bride Re-opens

Bride Reopens

In 2020, Clackamas Water Environment Services (WES) reopened the 82nd Drive Pedestrian Bridge to pedestrians and bicyclists after completion of several upgrades, which include seismically-retrofitting the bridge to withstand a magnitude 9.0 earthquake. The bridge is now capable of providing vital passage for emergency vehicles across the Clackamas River should such a catastrophic earthquake occur.

The upgrades also include newly-installed sanitary sewer pipes and provide additional protections for pipes and utility lines that run across the bridge.

“Increasing resiliency is the driving force behind all WES projects,” said WES Director Greg Geist. “WES is proud to support Clackamas County’s priorities, which include building a strong infrastructure and ensuring safe, healthy and secure communities.”

The $3.6 million project was funded with monthly service charge revenue and system development charges. WES secured required permits with the cooperation of the cities of Oregon City and Gladstone, the Oregon Department of Environmental Quality and the Oregon Department of State Lands. WES also collaborated with the Oregon Department of Transportation and the Clackamas County Department of Transportation and Development.

Built in the early 1920s, the bridge was once a state-owned thoroughfare for automobiles to cross the Clackamas River. The bridge was converted for pedestrian use after I-205 opened to traffic in the 1970s. In 1998, WES bought the bridge from the City of Gladstone in order to install sewer pipes that divert flows from WES’ Kellogg Water Resource Recovery Facility in Milwaukie to its Tri-City Water Resource Recovery Facility in Oregon City.

Charting the Bridge Upgrades

February 2020

Bridge as of February 2020

As upgrades on the bridge wound down, crew members were focusing their work on pipes carried by the bridge across the river, including the installation of a new forcemain and bolstering of existing pipes. 

January 2020

Bridge as of January 2020

Work to strengthen the structure of the bridge was finished. Crews installed a new forcemain pipe on the bridge while bolstering existing piping that was carried across the Clackamas River. 

December 2019

December 2019 bridge update

The bridge deck was replaced while work to strengthen supports under the bridge took place. Seismic upgrades were made to mechanical connections that attach the bridge deck to the supports. Crews also installed new force main piping and completed upgrades to existing piping that the bridge carries across the river.

November 2019

November 2019 bridge updates

Structural supports for the bridge were strengthened. Rock anchors were installed to stabilize the piers while pilings were driven into the ground to support the bridge where it connects to the road on the Gladstone side of the river. Existing piers were bolstered with concrete and rebar work. Steel beams were placed between the roadway on the Gladstone side and the first concrete pier, which allowed for the installation of the new deck.

October 2019

October 2019 bridge update

Pile driving on the Gladstone side of the bridge was completed while old wood timber supports and the bridge deck on the Gladstone side were removed. Work continued on strengthening the existing bridge piers and adding new supports. All in-water work was completed.

Bridge Charms

Dedicated August 28, 2009

Artists: Dale Wilhelm and James Schmidt

“Bridge Charms” is a sculptural work that consists of suspended stainless steel cable strung through the girders at either end of the 82nd Drive/Park Place Pedestrian Bridge. From the cable, dangle objects, bejeweling the bridge like a charm bracelet. The ornamental pendants represent the recreational uses of the Bridge/Clackamas River area, the natural aspects of the region and the historical references of the region. Additionally, circular colored pendants reflect color onto the Bridge and the surrounding environment. After extensive research and feedback from the stakeholder committee, WES employee and bird aficionado Dan Strong, Oregon City Mayor Alice Norris, and Erik Thorsgard and Tony Johnson, Cultural Liaisons from the Grande Ronde Confederation, the artists selected the following objects for the pendants:

  • Bicycle
  • Fly Fishing
  • Chinook Paddle
  • Fish Skeleton
  • Canoe
  • Model-T Automobile
  • Wagon Wheel
  • Old-fashioned Tree Saw
  • Cedar Osprey Sneaker (shoe)
  • Salamander Salmon
  • Old fashioned Faucet
  • Merganser (duck)
