Cayman Water is required under the water quality regulations contained in its License Agreement, and regulated by Water Authority-Cayman, to maintain a free chlorine residual in water supplied to our customers. The amount of chlorine added must maintain an average of approximately 0.25 parts per million of free chlorine residual. This ensures that the water is disinfected and remains free of any bacteria or other organics that might be harmful to the customer. Cayman Water tests approximately 65 samples of water each month for bacteria, in order to ensure that none is present in the water.
