Effective March 1, 2017, all residential members will be enrolled in the CareFlite Caring – Heart Membership Program. All household family members located at a single-residence service address will be covered for an ambulance transport within CareFlite’s service area. A fee of $1.00 per month will be added to each residential water account to pay for this membership. This monthly fee will protect against the out of pocket expenses of a CareFlite ground or air ambulance transport. If you have insurance, you will not receive a balance bill, If you have no insurance, you will automatically receive a 50% discount from CareFlite. Complete details and program rules are available at In order to opt-out of this program, the head of household will need to come to the Markout Water Supply office and sign an opt-out form.
