Aquarion Variance Programs
Please click one of the links below to begin the application process for an Aquarion Irrigation Variance:

  • Request A New Planting Variance

The New Planting Variance program ended on June 15 and it will reopen on September 1. However, there are no restrictions on drip irrigation, soaker hoses or hand-held watering at this time.

Customers with properties two acres or larger and feel they cannot efficiently water the property within the mandatory twice-weekly schedule can apply for this variance. In addition to a required on-site assessment of the irrigation system, the customer must also commit to a 15% water savings when compared to their 2015 usage. Systems must be water efficient and in good working order to be approved for a Large Property Variance. This variance program is available from April 6 to October 31.

Customers who have a high-efficiency irrigation system with Environmental Protection Agency (EPA) WaterSense® Weather-Based controller, which runs a schedule based upon site and weather conditions, can apply for this variance. An on-site assessment of the irrigation system is required and the customer must also commit to a 20% water savings when compared to their 2015 usage. With an approved variance, customers can water outside of the mandatory irrigation schedule. This variance program is available from April 6 to October 31.

Please check for EPA’s WaterSense® Label to see if you have a weather-based irrigation controller before applying for this variance.
