A. Water mains and water lines may be constructed and extended as and when determined by the board to be feasible and necessary in order to supply water to the inhabitants of the City of Austin.
B. As a condition to connecting or tapping into a water main or water line, the board may impose and collect a connection charge. In order that said connection charges be fairly and uniformly imposed, the board shall establish a schedule of connection charges which schedule shall be filed with the secretary of the board and which may be amended from time to time by the board in order to reflect changes in costs. Where a new water line is constructed or extended, the board may establish a connection charge for connection to that particular line based on the cost of the construction or extension and said connection charge need not be the same as the charge to connect to already existing water lines.
C. This section shall not be construed as limiting that authority to make water main or water line improvements under the Minnesota Local Improvement Code, Minnesota Statutes Annotated, Chapter 429 as amended, but shall be construed as powers granted in addition to and supplementary to the powers set forth therein.
