It is the intent of the Legislature to provide a means, in addition to the incorporation of districts authorized in Sections 19-5-151 through 19-5-207, by which not-for-profit corporations or associations involved in the sale, transmission and distribution of potable water to members of the public and others may convert their entity status from that of a body corporate to that of a body politic, thereby allowing those entities the opportunity to access the tax-exempt capital markets and thereby assuring the State of Mississippi and the customers of those entities of adequate supplies of water at the lowest water rates possible.
