Drinking Water FAQ

How do I shut off my water in case of an emergency? 

Look for your shut off valve in the following places:

  • In the crawl space or basement, where the water line enters the home.
  • In the garage where the water line enters the wall or ceiling, near the water heater or laundry hookup.
  • Outside near the foundation, often protected by a concrete ring or clay pipe.
  • Read more and see example of a shut off valve.

Your Water Meter 
Your water meter is located in a concrete or plastic box in the ground, generally in front of your house and near the side property line. It’s important to keep the box free of plants and roots that can obstruct or hide the meter or damage the service line.

Can't Find Your Shut Off Valve? 
You may want to have a shut off valve installed if you can’t locate one. If you have an emergency and need help shutting off your water at the meter or locating your water meter, please call OLWD at (503) 654-7765.

I have a leak. Will OLWS repair it? 

OLWS​ is legally not permitted to do any work behind the meter. Please call a ​plumber if you believe you have a leak. If you discover a leak, you may be eligible for a leak adjustment. You can learn more about detecting leaks and how to apply for a leak adjustment here.

Is there fluoride in my water? 

No, we do not add fluoride to the water. This is something that has to be voted in, and the majority of Oak Grove residents have voted against adding fluoride to our drinking water.

What is a Backflow Prevention Device? 

A Backflow Prevention Device is installed near your water meter is to protect both your drinking water and the district's water supply from contaminated water flowing back into the system. Oregon regulations require that backflow prevention devices be tested on an annual basis. If you have more questions about backflow please contact OLWS Customer Service Staff at (503) 654-7765.

Where does my water come from? 

Your drinking water comes from the Clackamas River

The Clackamas River is an extremely high-quality, raw water source. Timothy Lake and the Olallie Lake make up the head waters of the Clackamas River. These lakes are located high up in the Mount Hood National Forest. Along with the lakes, there are many other small tributary mountain streams that contribute to the flow of the river.

Where is the Water Treatment Plant? 

The treatment plant for drinking water is located at: 14275 S. Clackamas River Drive Oregon City, OR 97045.
