The Company shall provide a copy of the curtailment tariff to any customer, upon request.

Stage 1 Exists When:

The Company is able to maintain water storage and/or production in the system at 100 percent of capacity and there are no known problems with its well production or water storage in the system.

Restrictions: Under Stage 2, the Company may request the customers to voluntarily employ water conservation measures to reduce water consumption by approximately 50 percent. Outside watering should be limited to essential water, dividing outside watering on some uniform basis (such as even and odd days) and eliminating outside watering on weekends and holidays.

Whichever method is chosen the Company shall notify customers of the general nature of the problem and must state the following, “Should Curtailment Stage 2 persist or progress to further stages and the Company has an approved Emergency Water Augmentation Mechanism (“EWAM”).
