Commercial Irrigation Meter Installation Guidelines

Water meters installed for lawn irrigation and sprinkler systems shall be installed in parallel. Irrigation meters installed as a deduct meter are not permitted. Contact Public Works at 952-953-2400 for more information. 

Installation of irrigation meters in parallel allows for the independent reading of each meter, eliminates the need to calculate water use utilizing both the irrigation and domestic meter, and maintains consistency with established installation processes.
