Water Environment Services

WES is committed to planning for the future, which means proactively taking steps to ensure our facilities, equipment and infrastructure are up-to-date in order to provide state-of-the-art service to our customers.

To meet this challenge, WES is currently upgrading our Kellogg Water Resource Recovery Facility in Milwaukie. The Kellogg facility is undergoing a major refurbishment that is scheduled for completion in 2020. These upgrades will put Kellogg in an excellent position to provide dependable and cost-effective services for the next 20 to 30 years.

Dedicated to being a good neighbor to the community surrounding the Kellogg facility, WES determined that one of the major upgrades needed was to increase odor control. To achieve this, covers were placed on a portion of the aeration basins, which are large tanks that play key roles in breaking down pollutants.
Additional improvements include the replacement of pipes, pumps, electrical systems and other upgrades that will bring the facility up to full operational capabilities.

WES is strategically sequencing and staging the refurbishment project in order to keep the facility fully operational during construction

WES, in cooperation with other local jurisdictions, has developed a BMP Sizing Tool to assist developers in meeting flow duration matching requirements customized to Clackamas County conditions. The Tool sizes facilities so that post-development peak flow durations will match the pre-development peak flow durations ranging from 42% of the 2-year to the 10-year flows, as determined by HSPF continuous rainfall model simulation.

The BMP Sizing Tool automates some of the required calculations to support BMP sizing and design for a specific set of stormwater management facility types (See Section 9.0 of User's Guide).

Responses to frequent BMP Sizing Tool questions can be found in Appendix A of the User's Guide, including:

• Rain gardens, stormwater planters, vegetated swales, and infiltrators are referred to as LID facilities. The BMP Sizing Tool uses different methods for sizing LID facilities (Section 9.2) and detention ponds (Section 9.3).
• If there are multiple types of post-development surface covers on the site, each of the areas should be delineated separately and entered separately in the BMP Sizing Tool under the Discharge Management Areas tab. 
• Predevelopment surface conditions should reflect historical conditions (i.e., grass or forest). Even when the pre-development condition is impervious surface, it should be included in the BMP Sizing Tool as grass or forest.
• The BMP Sizing Tool sizes facilities to manage the 10-year peak flow (based on continuous simulation.) However, WES design standards require conveyance systems to be sized for the peak flow from a 25-year, 24-hour design storm.
• The BMP Sizing Tool is based on LID principles, including the concept of prioritizing small, distributed surface vegetated facilities. As a guideline, it is recommended that the area draining into a single BMP facility should not exceed approximately 10 acres.

The Watershed Health Education Program educates youth about the importance of protecting our watersheds. The program makes it possible for local teachers and their students to get out of the classroom and into the field, where they gain hands-on experience making assessments, restoring streamside habitats, and studying the factors that determine healthy rivers and streams. These students then share their knowledge with friends, family and the broader community through presentations and activities, making an even bigger impact on protecting public health and the environment. WES works with partners to educate K-12 students in our community, and some projects span multiple years. To learn more about this program and projects, please contact Gail Shaloum at gshaloum@clackamas.us.

WES protects watershed health and water quality in communities within northern Clackamas County. WES plans to upgrade several stormwater systems in the community.

This stormwater system improvement work is expected to begin in late August or early September and may take up to four weeks and cause minor traffic disruptions. On weekdays, work hours will be limited to 7 a.m. to 6 p.m. If work is necessary on a weekend, the schedule would be 8 a.m. to 5 p.m.  Diamond Court
