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.

There is no charge for the installation of a residential irrigation meter. However, a monthly fee will be billed for the additional meter. If you would like an irrigation meter, please fill out an application and return it to our Water Billing Office.

Smart Irrigation

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 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 possibly save money on your utility bill!
