State-of-the-Art Water Treatment
The new drinking water treatment method is conventional filtration plus ozone
The highly protected and pristine Clackamas River is the Partnership’s water source. Water is withdrawn from the Clackamas River intake, then travels in a large pipeline through Gladstone and under the Willamette River onto the water treatment plant in West Linn, where the water is treated to exceed safe drinking water standards. Treated water is then pumped through another pipeline to the Waluga Reservoir site in Lake Oswego. From here, water flows through pipes to Lake Oswego customers and to Tigard’s Bonita Road pump station.
As part of the upgrade and expansion of this system, a new treatment process was recommended by a panel of experts in drinking water treatment and public health. In 2017, the new plant will be utilizing a state-of-the-art water treatment process, conventional filtration plus ozone. Ozone, a powerful oxidant, destroys taste and odor causing compounds and removes more impurities from the water supply.
Ozone treatment offers multiple benefits:
- Provides an additional treatment barrier to protect public health
- Consistently produces water that is pleasant tasting
- Is capable of meeting emerging concerns for pathogens, algal toxins, disinfection by-products, pharmaceuticals, and personal care products
- Represents proven technology, with the number of ozone installations increasing in Oregon and across the U.S. due to its ability to provide multiple water quality benefits
