News & Announcements
Has your building been partially or fully closed for months during the pandemic? Letting water sit in pipes for long periods of time can have a negative impact on your building’s water quality. Learn what you should do before reopening your building.
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The City of Lake Oswego is updating outdated, manually-read water meters to a new, wireless-read technology.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 is seeking a new, more efficient wastewater treatment plant to replace the existing Tryon Creek Wastewater Treatment Plant (TCWTP), which needs significant investments to meet necessary DEQ requirements.
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.
