Let’s Celebrate National Drinking Water Week – May 3-9

Lake Oswego Mayor Kent Studebaker and Tigard Mayor John Cook celebrate reliable and safe drinking water at the new river intake pump station, on the Clackamas River.

When you turn on your tap and clean, safe water comes out...

Do you ever stop to think about how it gets there and where it goes when you're finished with it? The Lake Oswego Tigard Water Partnership and the communities of Lake Oswego and Tigard are celebrating Drinking Water Week from May 3-9. We invite you to celebrate by taking time to learn more about your water and celebrating the progress that is being made on your new water system.

Construction of the new system is well over half way–more than seven of the ten miles of large diameter pipe have been installed, and, by mid-2016, most major facilities will be complete and operational.

Once work is complete, Lake Oswego and Tigard will have the most reliable water system in Oregon—designed to modern earthquake standards, and utilizing an advanced treatment process that will produce safer and better tasting water year-round— delivered to homes and businesses all for about a penny per gallon!

In Oregon, we often take our drinking water for granted, but it's a finite resource. Significant costs and energy are required to treat our drinking water, deliver it to our taps, and manage the wastewater that goes down the drain. Spend a moment this week thinking about the essential role that water plays in your daily life.

Our water in Lake Oswego and Tigard is of the highest quality - let’s celebrate it!
