Customer Requests. If a customer asks the District to inspect its lines and facilities and the inspection shows that the customer’s problem arises from his private sewer or water lines, and not the District’s, the District may charge the customer the cost of such inspection, and the customer shall promptly remit the charge to the District. If a customer requests a re-read of its meter, the District shall re-read the meter at the District’s expense once during any six-month period. If such customer requests an additional re-read within six months, the District shall charge the customer $30.00 to re-read the meter unless such additional re-reading indicates that the meter was defective or has been misread.
