Fla. Stat. § 153.51
It is declared as a matter of legislative determination that the extensive growth of population and attendant industry and commerce throughout the state has given rise to public health and water supply problems of statewide concern, in that many unincorporated areas of the counties of the state are not served by water and sewer facilities normally and generally provided and maintained by the municipalities of the state or their agencies or instrumentalities or by private corporations or persons and are not otherwise adequately provided for; that many of such unincorporated areas are in extreme need of such sewage disposal and water supply facilities, and that it is the intent and purpose of this law to provide means for the counties of the state to alleviate such conditions in such unincorporated areas.
