The annual fee, called an assessment, pays the cost of construction, operation and maintenance of SRP facilities. It also includes delivery of that year's allocation of water.
Many shareholders use more than their allocation during an irrigation year.
There is a charge for over-allocation water use. Irrigated land is also charged an annual water delivery fee, which pays the administrative cost of servicing an active irrigation account. Bills are issued in mid-November for the upcoming year. They are due the first week of December. Failure to pay your assessment by the due date will result in penalties and may cause an interruption in your water delivery.
