FAQs

What is Backflow?

Backflow is contaminated water introduced into the city's main water supply lines due to either a direct or indirect cross connection. This can happen when there is backpressure or backsiphonage present.

What is Backpressure and Backsiphonage?

Backpressure is caused by pressure on the contaminated water side exceeding the pressure of the potable water line. This can be caused by pumping or the elevation of the contaminated water.

Backsiphonage is caused by a reverse draw of water. A vacuum or suction caused by a drop in pressure on the potable water side.

Why is Backflow prevention important?

It is our goal to provide our community with clean, safe drinking water. Backflow prevention is a key element to preventing potentially harmful matter from entering our system. Customer education and awareness is the first step to achieving this goal.

Who needs Backflow prevention?

Some properties and businesses have a greater potential for backflow events. The average household shouldn't require any additional protection. Residential properties that have irrigation or pressurized irrigation are not allowed to connect to city water for irrigation purposes. However, properties that qualify for an Application for use of City Water for Irrigation are required to have the proper backflow preventer in place. If you have a business and are not sure what needs protection, please contact our office, we would be happy to assist you.

Who is financially responsible?

The property owner is responsible for all installation, maintenance and testing assemblies. If it is proven to be a financial hardship, time extensions will be considered based on the degree of hazard deemed by the water purveyor.

How do I know for sure if I need one?

If you are unsure please contact our office. We can have a technician schedule an appointment for a site survey.

How much time do I have to comply?

Test reports are due yearly. One year from any previous test date. The tester will usually provide our department with the results in 30 days. The next due date will be updated in our system when that is received.

Who do I call to have my assembly tested?

Our office maintains a list of approved testers in our area. Please see list below, or you can call or email us and we will provide this list to you.
