Public Works

The Lake Oswego Public Works Department is responsible for maintaining infrastructure systems throughout the City to ensure they are working correctly, efficiently, and that the life of our assets is maximized. Streets, Water, Sewer, Stormwater, Motor Pool and City Beautification maintenance programs make up the department with each responsible for their own infrastructure system.

Here at Public Works, we take pride in providing utility maintenance to help make Lake Oswego a great place to live.

News & Announcements

Water is Safe to Drink

Our Lake Oswego-Tigard drinking water remains safe and reliable to drink and our treatment plant remains fully functional. There are a number of small water systems in Clackamas County (Mt Hood Hwy 26 area) that issued boil water notices due to pressure losses and power outages. Click here for a list of these areas. 

Water demands in the areas closest to the Clackamas wildfires have increased dramatically. Please do your part: reduce your water use and save water for fighting fires in our region. 

For more information visit the Clackamas River Water Providers website.
