Public Works & COVID-19

For the City of Lake Oswego, the health and wellbeing of our community is our top priority. This includes our daily, commonly out of sight city services, like drinking water and sewer.


Quality Water
First and foremost, our drinking water is safe. You can rely on us to continue to deliver safe drinking water to your tap throughout the COVID-19 emergency. The Center for Disease Control and Prevention has found that “the COVID-19 virus has not been detected in drinking water. Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate the virus that causes COVID-19.” Our comprehensive water treatment process utilizes conventional treatment plus ozone, filtration, and chlorine disinfection, providing multiple barriers that remove and inactivate viruses, bacteria, and other harmful organisms from the drinking water. Water is an essential service that we all rely on and we, as a City, will continue to ensure its reliability.

Protecting our Waste Water (Sewer) System
Toilet paper has been a hot topic these last few weeks throughout our nation. It may be challenging to find toilet paper, but we remind all our customers that paper towels, baby wipes, and “disposable wipes” can clog your pipes. These products do not dissolve and can clog sewer pipes, causing expensive - and time consuming - repairs for homeowners. These products also clog the larger public sewer pipes and pump station equipment which, in turn, leads to sewer backups. Save yourself and our collection system by placing wipes, rags, and towels in the trash, not the toilet!

Currently, Public Works and City Operations are still in effect. If you need to report an issue or have questions about Public Works infrastructure (streets, storm, water, sewer, etc), please contact Public Works by phone at 503-635-0280.
