Irrigation Service

Irrigation Banner

Approximately 9 billion gallons of water each day are used in the United States for outdoor residential use, mainly for landscape irrigation. It is estimated that about 50% of this water is wasted from over-watering or inefficient irrigation methods.

Irrigation control technologies (PDF) can substantially reduce outdoor water consumption by watering plants only when they need it. Consider installing a water efficient WaterSense labeled irrigation controller to reduce water waste and save on your utility bill!

Installation Standards

Lawn Irrigation Systems must be properly installed. Systems must be underground and completely enclosed without any faucets or sillcocks that could be connected or re-connected to the property’s domestic water service. The City’s construction standards for installation of the meter setter and standards of backflow prevention devices must be followed. View our diagram (PDF) of metered irrigation installation.

Irrigation Meter

There is no charge for the installation of a Residential Irrigation Meter. However, a monthly fee will be billed for the additional meter. Please fill out the Application for Residential Irrigation Service (PDF) if you would like an irrigation meter and return it to General Services (311 North State St., Concord, NH 03301).
