The rules, regulations and water rates of the water system of the City set forth herein shall be considered a part of the contract with each person who is supplied with water through the water system. Such person by taking water or connecting with such system shall be considered as expressing his assent to be bound thereby. Whenever any such rules and regulations or such conditions as the Common Council or Public Works and Safety Committee may hereafter adopt are violated, the water shall be shut off from the building or place of such violation, even though two or more parties are receiving water through the same pipe, and shall not be turned on again except by order of the Public Works and Safety Committee after payment of all arrears, expenses and established charges of shutting off, turning on and such other terms as the Committee may determine. These rules shall conform to the established rules and regulations of the State Public Service Commission or state statutes applicable thereto. In case of such violation, the appropriate authority may declare any payment made for the water by the party committing such violation to be forfeited. The Common Council or Public Works and Safety Committee has the right to change such rules, regulations and water rates from time to time as it may deem advisable and to make special rates and contracts in all proper cases, subject to the authority of the Wisconsin Public Service Commission.
