In the event any of the water meters fail to operate because they have become clogged by sand or for any other reason fail to function, so as to record the amount of water used, the water superintendent shall estimate the amount of water consumed based on former meter readings, condition of the premises and other pertinent data. If any person feels aggrieved by a bill based on such estimate, he may appeal the decision to the city commission. The city commission may, if it considers the position of the water user equitable and just, remit all or a part of such water bill except that it shall not remit the base minimum amount of such bill. (Prior code § 4-3-18)
