What is the Problem?

Each time it rains, water washes over our streets, driveways and yards picking up pollutants along the way and flowing into our storm drains.  This runoff may contain pollutants such as motor oil, yard clippings, pet waste, litter, lawn chemicals, anti-freeze or other toxins, which can pollute our water supply as well as clog pipes and culverts which can lead to flooding. Known as “Non-Point Source Pollution”, it is the largest threat to our waterways today.  Sometimes pollutants are dumped directly into storm drains by neighbors who don’t know any better. Contrary to popular belief, most storm drains are not connected to treatment systems, whatever enters the drains is discharged directly, untreated into local waterways! TO REPORT ILLICIT DISCHARGES TO STORM DRAINAGE’S, CALL 541-327-2768 AND PRESS 0 FOR AN OPERATOR.

 How can you help?
The storm drains inlets on your streets are being marked with a colorful marker, like the one displayed, with a pollution prevention message. You can help by using the following tips to prevent pollution.* Properly dispose of hazardous waste and recycle used motor oil
* Use fertilizers, pesticides, and herbicides sparingly and follow the manufacturer’s instructions.
* Keep yard waste, trash, and dirt off the street and out of the gutters.
* Clean up after your pets
* Wash your car at a car wash facility or park your car in the grass before you wash it.
* Spread the word about protecting our waterways from polluted runoff.

Thank you for your cooperation.

2022 New Water Treatment Plant

The new water treatment plant is now online!  Using products and technology from Pall Water, a global leader in filtration and purification systems for municipalities and industries alike, the City can now produce up to 2 million gallons of high quality water per day (MGD), with the ability to expand to 6 MGD to accommodate growth years from now.  This state of the art plant utilizes both UV and chlorine gas for disinfection, where the old plant relied only on chlorine, and was unable to produce more than 725,000 gallons a day.  The price tag for the new plant is about $10 million.  With advance planning, a history of stellar financial stability, and bringing more than $3.3 mill to the table, we obtained funding through Oregon’s Drinking Water State Revolving Fund Program, which granted the City $1 million in loan forgiveness AND an interest rate of 1%…all this, without having to raise water rates to the State’s official average, which is often required before loans are approved.
