(a) Bonds issued by an authority under sections 22a-500 to 22a-519, inclusive, may be issued under an indenture of trust or bond resolution, shall be general obligations of the authority, for which its full faith and credit shall be pledged, payable out of any revenues or other assets, receipts, funds or moneys of the authority and may be additionally secured by a pledge of revenues to be derived from the operation of a facility or wastewater system and other assets including a mortgage on real property and facilities, revenues, receipts, moneys and funds pledged therefor, subject only to any agreements with the holders of particular bonds pledging any particular assets, revenues, receipts, funds or moneys, unless the authority shall otherwise expressly provide by the indenture or resolution that such bonds shall be special obligations of the authority payable solely from any revenues or other assets including a mortgage on real property and facilities, receipts, funds or moneys of the authority pledged therefor, subject only to any agreements with the holders of particular bonds pledging any particular revenues, receipts, funds or moneys. (b) Any constituent municipality may enter into any agreement or agreements with such authority or with any person or persons to whom the proceeds of bonds issued pursuant to sections 22a-500 to 22a-519 , inclusive, have been loaned, for such periods and containing such terms and conditions as the municipality shall determine to be necessary or convenient to aid and cooperate in the planning, undertaking, construction, operation or financing of a wastewater system by such constituent municipality or by an authority, including, but not limited to, the guarantee by such constituent municipality of the punctual payment of all or some of the principal and interest on any bonds issued by an authority and the pledge of the full faith and credit of such constituent municipality to the payment thereof. As part of the guarantee of such constituent municipality for payment of principal and interest on the bonds, such constituent municipality may pledge to and agree with the owners of the bonds issued under sections 22a-500 to 22a-519 , inclusive, and with those persons who may enter into contracts with the authority or any successor agency pursuant to the provisions of sections 22a-500 to 22a-519 , inclusive, that it will not limit or alter the rights thereby vested in the bondowners, the authority or any contracting party until such bonds, together with the interest thereon are fully met and discharged and such contracts are fully performed on the part of the authority, provided nothing contained in sections 22a-500 to 22a-519 , inclusive, shall preclude such limitation or alteration if and when adequate provision shall be made by law for the protection of the owners of such bonds of the authority or those entering into such contracts with the authority. The authority may include this pledge and undertaking of a constituent municipality in such bonds or contracts. To the extent provided in such agreement or agreements, the obligations of such constituent municipality thereunder shall be obligatory upon such constituent municipality and the inhabitants and property thereof. Thereafter such constituent municipality shall appropriate in each year during the term of such agreement, and there shall be available on or before the date when the same are payable, an amount of money which, together with other revenues available for such purpose, shall be sufficient to meet such obligation. Any such agreement shall be valid, binding and enforceable against such constituent municipality if approved by an ordinance adopted by the legislative body of such constituent municipality or such other body as permitted by section 7-157 . (c) Any authority created pursuant to sections 22a-500 to 22a-519 , inclusive, may enter into long-term contracts or agreements with any municipality or any person or persons for water pollution control services whereby such contracting municipality or person agrees to connect its municipal wastewater facilities with the wastewater system of the authority for wastewater treatment and disposal service and to make payments of fees or charges based on a percentage of actual or projected flow or such other formula as such contract or agreement shall provide. Any such contract or agreement may require the continuation of such payments by such contracting municipality whether or not the agreed services are being provided but only until all bonds issued by any of the contracting parties for development and construction of water pollution control facilities or regional water pollution control facilities have been paid or the payment of such bonds shall have been duly provided for. Such contract may further require or permit one or more of the contracting municipalities to pay obligations of another contracting municipality in the event such other contracting municipality fails to make such payments and to bring appropriate legal action against the defaulting municipality to recover the amounts so paid, together with the costs and expenses of such action. The obligation of a contracting municipality to make payments pursuant to any such agreement shall not be included in the aggregate indebtedness of the contracting municipality for the purposes of any state statutory provision limiting the aggregate indebtedness of the municipality. Any such agreement shall be valid, binding and enforceable against the contracting municipality if approved by the adoption of an ordinance by the legislative body of such contracting municipality or by such other body as permitted by section 7-157 . The municipality may but need not be a member of the authority to execute any agreement under this subsection. (d) Any constituent municipality may enter into an agreement with the authority for the transfer to the authority, for use in the exercise of its corporate powers and purposes hereunder, of any water pollution control facilities or wastewater system of such constituent municipality as the same then shall be owned by such constituent municipality. Any such agreement may provide for the transfer of title of said facilities or wastewater system by deed, lease or other arrangement to the authority. To the extent it is not inconsistent with sections 22a-500 to 22a-519 , inclusive, any such agreement may impose such limitations or conditions as may be agreed upon with respect to the power thereafter to sell or otherwise dispose of any property acquired pursuant to such agreement and may provide for or authorize the authority to return property no longer required for water pollution control purposes. Notwithstanding the provisions of any other general, special or local law or charter, any action taken by such constituent municipality pursuant to this subsection shall not be subject to referendum. Any such agreement shall set forth the liabilities of such constituent municipality which are contemplated to be paid by the authority from moneys available to it, unless such agreement does not require the authority to assume any such liabilities. Notwithstanding the provisions of any other general, special or local law or charter, any moneys received by any constituent municipality in consideration for the transfer of such water pollution control facilities or wastewater system to the authority may be deposited in the general fund of such constituent municipality and used for any lawful municipal purpose or may be deposited in a special fund for the purpose of paying or redeeming any existing indebtedness issued for water pollution control purposes. A constituent municipality and the authority may make or enter into any contracts, agreements, deeds, leases, conveyances or other instruments as may be necessary or appropriate to effectuate the purposes of sections 22a-500 to 22a-519 , inclusive, and they shall have the power and authority to do so and to authorize the doing of all things incidental, desirable or necessary to implement the provisions of said sections. Upon the filing by the authority with the clerk of the constituent municipality and the Secretary of the State of a copy of the instruments or documents effectuating the transfer authorized by sections 22a-500 to 22a-519 , inclusive, the authority shall take possession of the water pollution control facilities or wastewater system of the constituent municipality. Any application filed or proceeding heretofore commenced in relation to the water pollution control facility or wastewater system transferred to the authority pending with the Department of Energy and Environmental Protection, the Department of Public Health or any other state agency or with the United States Environmental Protection Agency or any other federal agency or instrumentality shall inure to and for the benefit of the authority and be binding upon the authority to the same extent and in the same manner as if the authority had been a party to such application or proceeding from its inception, and the authority shall be deemed a party thereto to the extent not prohibited by any federal law. Any license, approval, permit or decision heretofore or hereafter issued or granted pursuant to or as a result of any such application or proceeding shall inure to the benefit of and be binding upon the authority and shall be assigned and transferred by the municipality to the authority unless such assignment and transfer is prohibited by federal law. If the municipality has outstanding general obligation bonds issued for acquiring or constructing water pollution control facilities acquired by the authority, whether or not the bonds are also payable from revenues, special assessments or taxes, the municipality may authorize the authority pursuant to the agreement to issue bonds under sections 22a-500 to 22a-519 , inclusive, for the purpose of retiring the outstanding bonds or alternatively, the authority may agree to pay the principal of and interest on such bonds until the obligation of such constituent municipality is discharged. No such agreement under the provisions of this subsection shall be executed until such constituent municipality shall have held a public hearing at which users of the water pollution control system and residents of such constituent municipality shall have had the opportunity to be heard concerning the proposed provisions thereof. Notice of such hearing shall be published at least thirty days in advance in the official newspaper or newspapers of the municipality. (e) The rates, fees, charges, penalties and assessments established by an authority under sections 22a-500 to 22a-519 , inclusive, shall be established so as to provide funds sufficient in each year, with other revenues, if any, available therefore (1) to pay the cost of maintaining, repairing and operating its wastewater system and each and every portion thereof, to the extent that adequate provision for the payment of such cost has not otherwise been made, (2) to pay the principal of and the interest on outstanding bonds of the authority as the same shall become due and payable, (3) to meet any requirements of any resolution authorizing, or trust indenture securing, such bonds or notes of the authority, including coverage requirements, (4) to make agreed upon payments in lieu of taxes, as the same become due and payable, upon the properties of the authority to the municipalities in which such properties are situated, (5) to provide for the maintenance, conservation and appropriate use of the land of the authority, and (6) to pay all other reasonable and necessary expenses of the authority. No such rate, fee, charge, penalty or assessment shall be established until it has been approved by the authority and after the authority has held a public hearing at which all the users of its wastewater system, the owners of property served or to be served and benefited or to be benefited and other interested persons have had an opportunity to be heard concerning such proposed rate, fee, charge, penalty and assessment. The authority shall not approve such rates, fees, charges, penalties and assessments unless it finds that such rates, fees, charges, penalties and assessments will provide funds in excess of the amounts required for the purposes described previously in this section, or unless it finds that such rates, fees, charges, penalties and assessments will provide funds sufficient for such purposes. The rates, fees, charges, penalties and assessments so established for any class of user or property served or to be served shall be extended to any additional user or property thereafter benefited or owned which are within the same class, without the necessity of a hearing thereon. Any change in such rates, fees, charges, penalties and assessments shall be made in the same manner in which they were established. (f) All required payments of rates, fees, charges, penalties and assessments, interest on loans, principal of loans and necessary fees and assessments related thereto required under any contract or agreement entered into pursuant to the provisions of this section, shall be considered expenditures for public purposes by a municipality and, notwithstanding the provisions of any other law, any necessary general or special assessments, fees, rates, charges, penalties and assessments or cost sharing or other assessments authorized to be levied, charged or assessed and collected by municipalities within the state or with respect to fees, rates, charges, penalties and assessments by an authority in accordance with sections 22a-500 to 22a-519 , inclusive, may be levied, charged, assessed or collected by said municipality or an authority without limitation as to rate or amount for the purpose of making such required payments.
