La. Stat. tit. 33 § 3885
Sewerage districts created under this Subpart shall constitute public corporations, and as such shall have all powers of public corporations, including perpetual existence; the power to incur debt and contract obligations; sue and be sued; to have a corporate seal; to do and perform all acts in their corporate capacity and in their corporate names, which are necessary and proper for the purpose of constructing and maintaining sewers and sewerage disposal works within their territorial limits; and generally to perform any and all acts and duties necessary to carry out the objects and purposes of their creation. These sewerage districts may expropriate property for the purpose of acquiring rights of way for the laying and installing of sewers and sewerage disposal works, and may acquire machinery, tools and equipment, essential to the proper accomplishment of the purposes of their creation.
Any sewerage district, through its governing authority, may by an ordinance or resolution establish, maintain and collect rates, charges, or connection charges for any service rendered by the sewerage district to be paid by the owner of each parcel of real estate, or building that is connected with and uses or is served by the sewerage system of the district, and may readjust such rates, charges or connection charges, from time to time. Rates or connection charges shall be sufficient in each year for the payment of the proper and reasonable expenses of operation, repair, replacement, and maintenance of the sewerage system and for the establishment of the necessary sinking fund for the payment of the principal and interest of any revenue producing public utility bonds which may have been issued and sold for the purpose of constructing, acquiring, extending or improving the sewerage system. The governing authority of the sewerage district shall adopt and enforce rules, regulations and ordinances, exact penalties, and institute such actions at law as are within its corporate power, for the prompt collection of the respective rates or connection charges fixed for service rendered by the sewerage system.
