(a) The Sparta Aquifer critical groundwater county conservation board may levy and fix upon each registered water user and significant water user of aquifer water a conservation fee in an amount deemed appropriate by the board to discourage the withdrawal of aquifer water by registered water users and significant water users.
(b) However, when the board has extended an alternate water source to the property line of a major water user and the major water user does not connect to and begin using the alternate water source, the major water user may be assessed a conservation fee determined by the board, not to exceed one and five-tenths (1.5) times the board's current rate for the alternate source per one thousand gallons (1,000 gals.) of aquifer water withdrawn, until the major water user connects to and uses the alternate water source.
