News & Announcements
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.
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.
We're here for you, through every emergency. Get to know your drinking water by reviewing the 2020 water quality report.
The City of Lake Oswego is updating outdated, manually-read water meters to a new, wireless-read technology. These smart meters support efficiencies in our water system.
The City of Lake Oswego is seeking a new and more efficient wastewater treatment plant to replace the existing Tryon Creek Wastewater Treatment Plant (TCWTP) located in Lake Oswego, Oregon.
As new technology emerges, the use of wireless devices and data usage has drastically increased. However, as data usage has increased, carriers are needing additional small cell wireless infrastructure to supplement service.
