Drinking Water

Clean drinking water, reliable services, and healthy waterways are cornerstones of a vibrant community. OLWS provides safe and reliable drinking water services to approximately 29,000 residential and commercial customers. Raw water from the Clackamas River is drawn by the North Clackamas County Water Commission (NCCWC) Water Treatment Plant, where it is treated, cleaned, and transformed into high-quality drinking water. OLWS operates and maintains a complex set of infrastructure responsible for storing and distributing drinking water to its customers. 

OLWS has been voted as one of the top three best tasting water in the Pacific Northwest Section of the American Water Works Association, Best Tasting Water Competition multiple times. OLWS continues to be committed to giving you the best water we can.

Water Master Plan
The Water Master Plan (WMP) offers a 20-year outlook of the community’s water resources, including available water supply, current and future demands, and emerging water quality considerations. It evaluates the condition of water infrastructure (pipelines, pump stations, tanks, etc.) and provides recommendations for replacement and repairs. Additionally, the WMP explores the system’s ability to withstand unexpected emergencies such as fires,
floods, or earthquakes. OLWS updated its Water Master Plan in 2020 to ensure adequate water supply and reliable services for decades to come.

NOTE: Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants may be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. The U.S. EPA/CDC (Centers for Disease Control and Prevention) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791.
