The Village of Grand Rapids must provide a safe and reliable source of drinking water to all customers and protect the public water system from any possible source of contamination.  It is possible that a source of contamination may come from our own customers.

As required by the Ohio EPA (OAC 3745-95) and Village Ordinance 1040.02, the Backflow Prevention and Cross-Connection Control Program helps to ensure the water that is delivered to every customer is meeting water quality standards.

Residential Water Customers 

At a minimum, the Village requires a dual check backflow prevention device to be installed at your residence just after your water meter.  This protects the public water system.  However, a cross-connection at your residence can create a potential health risk to you and your family due to the backflow of contamination into your drinking water piping.  See below for more information.  If you are unsure if a potential cross-connection exists at your property or have questions, please contact us at:

Commercial and Industrial Water Customers Annual Testing of Backflow Prevention Devices
All backflow prevention devices are required to be tested annually.   The tests are performed at the expense of the customer and shall be performed by a person qualified to inspect and test backflow prevention devices.  The annual test results are required to be submitted to the Village of Grand Rapids.

What is a cross-connection?
Any physical connection created between a possible source of contamination and any public water system piping.

What is backflow? 
The flow of water or other liquids or substances through a cross connection from a possible source of contamination back into the public water system.

How can a backflow occur?
When a cross-connection is created and a pressure reversal, either as backsiphonage or backpressure occurs in the water supply piping.

What is a backflow prevention device?
Any device intended to prevent the backflow of water from a customer water system to the public water system.  These devices are typically installed close to the water meter.  (Note: A customer can also install additional backflow prevention devices on their piping system to protect  their internal water system.  Check with your plumber for guidance.)
