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.

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:

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.
