Water
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, all the way to your tap.
One of the most important things that a homeowner can do to save water is make sure that equipment is functioning appropriately and is efficient. The City offers free Water Audits to help citizens find ways to use less water. Water audits are performed during the spring and summer seasons when watering yards begins.
