Almost 15 years ago, Lake Oswego and Tigard formed a partnership to share drinking water resources and costs. Lake Oswego’s facilities were undersized, aging and seismically vulnerable. Tigard had pursued ownership of its own water source for many years. By sharing the cost of planning, designing and constructing a new water supply system, each city secured its long-term water supply needs at a cost neither could afford alone.
On June 9, 2016, the Lake Oswego Tigard water system became fully operational, and the Clackamas River became both LO and Tigard’s primary source of drinking water. Watch Lake Oswego Mayor Buck and Tigard Mayor Snider reflect on how important this partnership has been – and continues to be – for both communities.
This truly is a partnership that is built to last and continues to live up to the motto – sharing water, connecting communities.
Tap water is one of the most important resources in our lives. Did you know, your Lake Oswego and Tigard drinking water is rigorously tested for over 90 contaminants and goes through six stages of treatment before ending at your tap, all for about a penny per gallon?
💦 Clean, safe, high-quality drinking water is delivered to almost 100,000 customers using an advanced treatment system and network of resilient pipes, pump stations and reservoirs. 💧 For this high-quality tap water, delivered straight to your home, you pay about a penny per gallon; compare that to $1.00 for one 16-ounce bottled water that is not required to meet the same rigorous testing standards as tap water.
A lot of work takes place behind the scenes to provide us with clean, safe and reliable drinking water every day.

It’s #DrinkingWaterWeek – so take a look inside the heart of the Lake Oswego Tigard Water Partnership’s water treatment plant and learn about the path to purifying your drinking water.
It’s #FixALeakWeek! Did you know, household leaks can waste nearly 1 trillion gallons annually nationwide? That’s the annual household water use of nearly 11 million homes. This week, along with EPA Water Sense and the Regional Water Providers Consortium, we are challenging you to take 10 minutes to look for household leaks that can be easy to fix.
The recent snow and ice storm resulted in extensive power outages throughout Lake Oswego and our metro region. The City of Lake Oswego lost power at all main facilities, including the LO-Tigard river intake pump station and the water treatment plant that provides water to 100,000 customers in Lake Oswego and Tigard.
While Partnership staff worked tirelessly to secure generators and restore temporary power, LO turned to their partner for help. In a precautionary effort, the Partnership activated our emergency water intertie at our Waluga Reservoir site. For the first time since the intertie was installed, the flow of water was reversed, with Tigard supplying water to Lake Oswego’s reservoirs. This ensured the Lake Oswego community would not go without drinking water and our emergency responders had ample storage for responding to fires.
While challenges needed to be overcome, this was a great testament to the incredible partnership with Tigard and Lake Oswego. Thank you, Tigard. This truly is a partnership that is built to last and continues to live up to our motto – sharing water, connecting communities.
Has your building been partially or fully closed for months during the pandemic? Flush Your Water Pipes!
Many offices, schools, and other buildings have been partially or fully closed due to the pandemic. Water sitting in pipes for long periods of time can create water quality challenges and potential health risks that should be addressed prior to returning to more normal operations. Fresh water should be drawn into building water systems and stagnant water flushed out before they are reopened.
As a water provider, we control microorganisms – including Legionella, the bacteria that causes Legionnaires’ Disease – as part of our routine treatment operations. Once water enters a home or building, the resident or building manager is responsible for maintaining water quality in their home or building plumbing system.
How to flush your system
Flushing your water pipes is an easy way to help maintain quality by removing the older water out of the pipes and bringing fresh water in. Follow the simple steps outlined in the graphic below!
