Building Safety Month: Water Safety

What’s Backflow?

The topic for week 2 of Building Safety Month is Water Safety.

In the City of Bonney Lake, backflow assemblies play an important role in water safety. It’s possible you’ve never had to learn what a backflow prevention system is – but you can think of it as a one way gate that allows water from the City’s water supply to flow into your home’s piping but stops water if and when it tries to flow backwards into the main water supply. Backflow assemblies are common in lawn irrigation systems, plumbing lines for filling pools, and soda machines.

So what’s the big deal? Preventing backflow protects our drinking water from contamination from sources like your dishwasher and pool. Clean water is important for all members of our community. Additionally, backflow assemblies play a role in keeping the water pressure in service delivery lines consistent which makes sure water flows from the tap.

A backflow device is required to be installed at all actual or potential cross connections. These assemblies must be registered with the City and tested annually by a Certified Backflow Assembly Tester. Any parcel that utilizes the City of Bonney Lake as their water purveyor is required to pull a plumbing permit for the installation of a backflow device. It is a $100.00 permit and can be applied for using the plumbing application.

So let’s work together to keep our drinking water safe, clean, and available!
