Backflow devices are mechanical devices designed to prevent the backflow of pollutants or contaminants from entering the safe drinking water system.

For example: you want to spray your lawn or garden with fertilizer, so you hook one end of the hose to the faucet at the house and the other end to the sprayer containing fertilizer.  If there is a sudden change in water pressure the fertilizer in the sprayer can be drawn into your homes water system.  A backflow device would keep this from happening.

If you have an irrigation system, swimming pool, hot tub, or your home is elevated above the water meter, you may need a backflow device.  If you’re unsure, call GAWSA at 541-679-6451 and we’ll send out a representative to see if you need one.

The state requires that backflows be tested annually.  If you have a backflow device, GAWSA will send you a reminder notice the month prior to when your test is due.  If you do not have your backflow device tested by the date noted on the notice, GAWSA will have it tested for you and the fee applied to your account.

For your convenience, GAWSA has provided a list of backflow testers who service Douglas County.
