Know Your Water

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.

Celebrating a Successful Water Partnership

June 9, 2021 marks five years since the new Lake Oswego Tigard water system started providing high-quality drinking water to almost 100,000 customers throughout Lake Oswego and Tigard!  

Here are six things to know and celebrate about this successful partnership:

  • Water quality has improved with a state-of-the-art treatment system.
  • Through partnering together, both cities saved millions of dollars for customers.
  • The Lake Oswego Tigard Water Project was the largest public works project in our cities’ histories.
  • Our water system meets the most modern seismic standards for long-term resiliency and increases emergency water supply reliability through regional intertie connections.
  • Our Water Treatment Plant eliminates emerging pathogens/viruses, like COVID-19, from the water supply.
  • Our water system provides reliable, consistently high-quality drinking water from the Clackamas River—all for about a penny per gallon.

Let’s celebrate securing our most valuable resource for our cities’ future: investing in public health and preparing our cities for the long-term.

Your Drinking Water: There When You Need It

No matter the weather or the emergency, there are hardworking water professionals braving the elements to maintain all the infrastructure needed to ensure high-quality drinking water is There When You Need It for LakeOswgo and Tigard residents. A lot of work takes place behind the scenes to provide customers with clean, safe and reliable drinking water every day.

During Drinking Water Week, let’s recognize and celebrate the tireless work these Unsung Heroes do, to ensure we all can enjoy nature’s most precious resource. This video shares the story of these heroes who work day and night to deliver the highest quality drinking water available to your home!

A Path to Pure Water

It takes a lot to deliver just about any high-quality product, and our Clackamas River drinking water is no exception. It includes an intricate maze of infrastructure – treatment plants, pipes, pumps, storage basins and treatment supplies – to ensure your drinking water is #ThereWhenYouNeedIt.

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.

Fix A Leak Week

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.

Follow along with the #FixALeak checklist:

Thank you, Tigard

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.

Flush Your Water Pipes

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!

The American Water Works Association has also developed flushing instructions.

Where to find safe building reopening resources 

Building managers can find guidance on reopening buildings, information about potential hazards, and best practices for flushing from the Centers for Disease Control and Prevention (CDC) and the Oregon Health Authority (OHA).

If you have questions or concerns about reopening your building or your water quality, we are here to help. Please email us or call 503-635-0394.
