The purpose of this act is to provide for the establishment of a quasi-municipal body corporate of the state within and embracing all of Johnson county, Kansas, to be known as “Johnson county wholesale water supply district.” The said county contains a heavy concentration of population with a large number of incorporated cities and unincorporated areas which are constantly increasing in population. It lies adjacent to two large cities within and without the state, and industrial, residential, and commercial expansion is rapidly occurring. Sources from which a permanent and satisfactory supply of water can be obtained are very limited and isolated. Special utility problems confront the said county which cannot be solved by separate municipal action, but require a cooperative effort throughout the said county. The function of the district shall be to secure a source of water on a scale larger than is feasible for public water supply districts, municipalities, publicly and privately owned water distribution companies, acting alone, and to sell such water at wholesale to public water supply districts, municipalities, and publicly and privately owned water distribution companies.
