City of Tigard

Tigard’s main supply of drinking water originates from the Clackamas Water, one of the greatest quality sources within the state. The Clackamas Water begins in Attach Hood National Woodland, drawing from a watershed section of 940 square kilometers. Water is withdrawn in the Clackamas River, pumped via a pipeline buried underneath the Willamette River, and treated in the Lake Oswego Tigard Water Remedy Plant in Western Linn. The water experiences a robust treatment process which includes filtration to get rid of dirt and microorganisms, ozone to get rid of substances that affect the way the water tastes as well as smells, and disinfection to kill organisms as well as protect the water since it goes through the actual distribution system. The Lake-Oswego Water Remedy Plant expansion and also the infrastructure that links the plant towards the City of Tigard had been completed in 2016. These investments within the water supply program have paid large dividends for Tigard Water Support Area customers – customers possess a new, resilient supply of supply with superb water quality.
