The City of Lake Oswego operates and maintains a Water Treatment Plant in West Linn, as well as a distribution system, a water conservation program, and a cross connection control program.
Water plays a vital role in everyone’s life. The Water Department’s mission is to bring healthy drinking water of the highest quality to Lake Oswego’s residential and wholesale customers from our intake facility on the Clackamas River in Gladstone.
Water Treatment Plant staff have responded to many water customer requests for lead samples over the past year.
As required by the Oregon Health Division, the City of Lake Oswego has developed a cross connection control program. Its purpose is to protect the public water system as well as the citizens' private water system from possible contamination, and provide the best possible water quality.
City personnel can assist with water shut-offs for home/business owners in the case of a leak, needed repair, or emergency. Please contact Maintenance (503) 635-0280 to get your water turned off.
The cities of Tigard and Lake Oswego joined together in 2008 to share the costs of upgrading Lake Oswego’s water infrastructure and to provide high-quality drinking water year-round to both communities.
If you are experiencing odd tasting, odorous, or colored water there are basically two causes that could be occurring:
- A problem with the City of Lake Oswego source water.
- An interaction of disinfection agents with a build-up of organic material in your home's plumbing system.

The water meter is a City owned device that measures the quantity of water used by a citizen or business. It is the device that meter readers read for every billing cycle to determine water usage. It is important to help the meter reader by maintaining the area around your meter.
