Water Pollution Prevention A Guide for Property Managers
The following best management practices are recommended to prevent water pollution at apartment complexes and multi-family housing units.
Report Spills
Report spills and inappropriate discharges of wastewater into the storm system by calling WES: 503-742-4567. For significant hazardous material spills, call 9-1-1, and ask the dispatcher to notify WES.
Maintain Storm Drains
Property owners are responsible for maintaining storm drains and stormwater facilities (swales, ponds, etc.) on their property. Clackamas County Water Environment Services (WES) Storm Drain Cleaning Assistance Program (SCAP) offers low-cost storm drain cleaning: www.clackamas.us/wes/swm#stormdrain
Waste Management
Uncovered solid waste, recyclables, and chemicals can be sources of stormwater pollution. Please cover or move these materials inside. Sweep and pick up additional debris instead of hosing or pressure washing pollution into the storm system.
Pick Up Dog Waste
Dog poop that is left on the ground can wash into storm drains and contaminate our streams and rivers. Please consider providing a dog waste bag dispenser with biodegradable bags to encourage tenants to pick up waste immediately and dispose of in a garbage can.
Paints & Stains
Store all chemicals in closed containers and clean up all spills immediately. Use ecofriendly paints and stains. Look for products that do not contain zinc, copper, or other pollutants, which enter the environment with stormwater runoff. Select safer choice products: www.epa.gov/saferchoice/products
Wash Vehicles Off-Site
Stormwater systems in this area drain to the nearest creek or river. Please don’t wash vehicles in parking lots or streets. Encourage tenants to use a commercial car wash that recycles water and discharges to the sanitary sewer.
Stormwater Management
To reduce the amount of pollution entering our rivers and streams, slow down your stormwater and allow for water infiltration into the soil. Go the extra mile: Install a rain garden or parking lot swale to infiltrate stormwater on-site.
Avoid Zinc & Copper
Treating moss with zinc and copper products creates runoff that is harmful to aquatic life. If using chemical controls, pick a safer product for people and the environment by visiting www.growsmartgrowsafe.org
Use Natural Controls to Manage Moss
- Reduce shade by pruning branches
- Use a stiff bristled brush or broom to remove moss
- Correct acidity problems with lime after soil test
- Correct drainage problems
- Avoid pressure washing when possible
- Avoid powdered soaps during rainy season
- If using chemical controls, disconnect downspout to retain roof runoff onsite

Kellogg Creek Bioblitz
Help the North Clackamas Watersheds Council to document the plants, birds, insects, and other wildlife that are currently present in and around the soon-to-be restored Kellogg Creek. We will meet at 9:30 in the back parking lot of the Milwaukie Presbyterian Church. Surveys take place from 10 am – Noon, with a celebration and free lunch provided by the Council afterwards!
3-Creeks BioBlitz
Volunteers will be gathering data on birds, plants, fungi, amphibians, and whatever else we can find. This is a special opportunity to safely explore this beautiful natural area, which is typically closed to the public. There will be opportunities to learn more about the restoration work in progress at this site, and hopefully see some wildflowers, and observe signs of urban wildlife!

Budget in Brief Fiscal Year 2025-26
TOTAL BUDGET - $247.6 Million
Clackamas Water Environment Services’ (WES) budget for the fiscal year (FY) 2025-26 reflects the resources needed to continue delivering essential services for nearly 200,000 residents, businesses, and other key stakeholders within our diverse service area.
Mission: Why We’re Here
Clackamas Water Environment Services produces clean water, protects water quality, and recovers renewable resources. We do this by providing wastewater services, stormwater management, and environmental education. It’s our job to protect public health and support the vitality of our communities, natural environment, and economy.
Vision: Where We Are Going
Be a collaborative partner in building a resilient clean water future where all people benefit, and rivers thrive.
Budgeted Revenue - $69.3 Million
In FY 2025-26, WES’ budgeted revenue comes from:
• Sewer Charges: 68.3%
• Surface Water Charges: 10.5%
• System Development Charges: 11.6%
• All Other Revenues: 9.6% 
How WES is Funded
WES is 100% funded by our customers. Monthly sewer and surface water rates, along with system development charges (SDCs) for new connections, fund the cost of operating, maintaining, and building WES’ systems.
WES sets rates carefully to:
- Cover the day-to-day operating costs necessary to treat wastewater, manage stormwater, and protect water quality.
- Fund major capital projects to renew aging infrastructure and support growth.
- Repay debt for system improvements in a responsible, affordable manner.
The Bottom Line: Household Impact
FY 2025-26 rate increases support growing operating and maintenance costs and provide funding for capital projects necessary to maintain safe, reliable infrastructure.
Proposed rate increases average $1.25 per month, or $15.00 annually, for most residential customers.
Even with these necessary increases, WES’ monthly rates for wastewater and surface water remain below the average rates in the surrounding area.
