Help us protect the sanitary sewer system
Wipes, paper towels and other "unflushables" can create a sewer backup in your home. Flush only toilet paper and protect your home, the sewer system, and the environment.
When it comes to deciding what to flush down the toilet, Stick to the three P’s: pee, poo and toilet paper.
Fats, oils and grease (FOG) are found in common foods and food ingredients such as meat, fish, butter, cooking oil, mayonnaise, milk, gravies, sauces and food scraps.
Cleaning out your medicine cabinet? Don’t flush old or unwanted medications down the toilet or drain.
Help us protect the watersheds
Although convenient for cleaning surfaces and equipment, pressure washing can send dirty runoff into the storm drain system.
Trash on the ground can pollute our waterways. Here's how you can help.
Prevent polluting our streams and underground drinking water supplies.
Learn from KPTV Meteorologist Mark Nelsen in this friendly video reminder from WES, KPTV and our other Clean Water Partners.
Clackamas County has almost 100,000 dogs of all shapes and sizes. The FDA estimates that a dog excretes 0.75 pounds of waste per day. That adds up to nearly 13,000 tons of pet waste in our county per year!
Keeping your lawn free of weeds involves many choices — some are hazardous to our families, pets and waterways.
Heavy rains and fall leaves can cause high water and increase pollutants reaching our streams and rivers.
The following best management practices are recommended to prevent water pollution at apartment complexes and multi-family housing unit.
Ask your landscape maintenance contractor to use these best management practices to help protect our waters, our environment and those you love.

BMP Sizing Tool
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.

Watershed Health Education Program
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.
