(a) The charges for the use of the sewerage system may be changed from time to time and except as otherwise provided in W.S. 15-7-407 shall be fixed at a rate which equitably distributes the cost of service among the users. If any service charge is not paid within thirty (30) days after it is due, the amount thereof, together with a penalty of ten percent (10%), and a reasonable attorney's fee, may be recovered in a civil action by the city or town.
(b) Any city or town issuing bonds under this article shall maintain a proper system of accounts showing the amount of revenue received from the sewerage system and its application. At least once each year the accounts shall be properly audited and a report of the audit shall be open for inspection at all proper times to any taxpayer, sewerage system user or any holder of any bond issued under this article, or their respective representatives.
