Home MenuIrrigation
As part of our long-term water resource management, the Town encourages wise water use and regulates irrigation from in-ground, automatic irrigation systems and above-ground irrigation.
Required Backflow Testing
PLEASE NOTE: A backflow prevention device is REQUIRED for an irrigation system. State law requires that you test your backflow prevention device every three years. Learn more about Cross-Connection Control ordinance & program here
Watering Ordinances
Irrigating with any system that uses potable water, including hose and sprinkler connections, must follow the Town's year-round watering ordinances. Customers who irrigate with reclaimed water, pond or well water are exempt from the Alternate-Day Way Watering Ordinance. Submit a 45-day exemption to the alternate day watering schedule to establish new turf or for seasonal reseeding.
Irrigation with a hose and sprinkler incurs water and sewer charges unless the water comes through a separate irrigation meter. To incur only water charges for irrigation, consider one of these three options.
In-Ground Automatic Irrigation System Installation
Installing an automatic irrigation system using potable, reclaimed, well or pond water requires it meets our irrigation design standards and is permitted. Upload the following documents and the irrigation plan after registering to submit an irrigation permit via the plan review portal.
- Water and Sewer Service Application
- Irrigation Checklist
- Reclaimed Water Use Statement of Compliance (reclaimed water systems only)
- Minor Right-of-Way Encroachment Agreement
If you are installing an automatic irrigation system that costs at least $2,500, it must be installed by a licensed irrigation contractor in accordance with North Carolina law. Visit North Carolina Irrigation Contractors' Licensing Board for details. Maintain your system throughout the irrigation season to keep it watering effectively.
The Town encourages home-owners and businesses to consider drought-tolerant grasses. Learn more about Landscaping strategies and conservation tips.
