Backflow Prevention

All irrigation systems require a permit and a backflow prevention system installed and inspected. The backflow prevention is mandatory for the integrity and safety of our municipal water system. Failure to do so, exposes our water system to contamination.

Irrigation systems previously installed without a permit, will need to be inspected to insure proper connection. Please contact the Lyon Township Building Department for a permit application and to schedule an inspection.

If you are not certain a permit was issued for your irrigation system, call the Building Department for verification at 248-437-2252.

Future irrigation systems will require a plumbing permit issued prior to installation, a backflow preventer installed and certified, and a final inspection by the Township. Please contact Lyon Township Building Department for further information: 248-437-2252.
