ET Controller Registration

Why You Should Register Your ET Controller

If you are a McKinney resident whose irrigation system is equipped with a qualifying ET controller, you can register your controller with the City of McKinney and receive a watering day exemption from the city's current watering schedule.

For more information, please call 972-547-7360 or send an email.

Program Guidelines

This program is for residential and small commercial lots that utilize controllers on the approved list.
  • You must have a City of McKinney water utility account in good standing for the property where installation of the qualifying item is to occur.
  • A one-time nonrefundable registration fee of $25 is required for initial registration. You are responsible for re-registering the ET Controller, free of charge, prior to the anniversary date each year.
  • The city-issued “ET Controller” yard sign must be displayed and visible from the street to acknowledge the watering day exemption. Restrictions pertaining to time-of-day, watering during rain or freeze, and broken/misdirected heads still apply. The ET controller yard sign is the property of the City of McKinney and can be removed for non-compliance.

  • The City of McKinney reserves the right to alter the details of this program at any time.
