Irrigation & Backflow Prevention

Backflow prevention devices are required on homeowner irrigation systems to prevent contamination from being drawn into the town's water system. This requirement applies to homeowners with two meters and to homeowners who have an irrigation system connected to a house meter.

The state requires that towns have programs to prevent such cross contamination and recommends that devices be inspected and certified annually. These inspections are the homeowner's responsibility.

Getting a Backflow Prevention Device Inspected

A letter will be mailed to residents with backflow prevention devices each year 30 days before inspection and certification is due. Here's what to do:

• Find a Tester - Contact a certified plumber or certified backflow tester of your choice not affiliated with the Town to complete the inspection. Don't have an inspector? Click here to get started.
• Get the Inspection - The tester will confirm that the device is working properly. The tester will submit the results directly to AquaResource, which manages prevention device data for the town.
• Check Test Results - Click here to ensure the submission of your device test and the result.

If you don't want to have the backflow prevention device on your irrigation meter inspected, contact us to have your irrigation-only water meter turned off.
