The City Council finds that by reason of the overdraft of the water table from which the City takes its domestic water supply, and because of the current problem existing with respect to the over use of the waste of water in connection with the irrigation of landscape and other outdoor vegetation, lawns and other growth, it is necessary to adopt and enforce a water conservation plan to conserve the water supplies of the City for the greatest public benefit with particular regard to domestic use, sanitation, and fire protection; and it is the intent of the City Council to achieve at least an approximately ten percent (10%) reduction in water use.
