Conn. Gen. Stat. § 7-259
Whenever a municipality has authorized the acquisition or construction of all or any part of a sewerage system, whether located within or without such municipality and whether constructed or acquired by such municipality acting alone or jointly with one or more other municipalities, and has made an appropriation or has incurred debt therefor, or has made an appropriation for the purpose of contributing funds to another municipality located within or without this state for sharing the costs of acquisition or construction by such other municipality of all or any part of a sewerage system which will benefit the municipality making such appropriation, it may issue bonds, notes or other obligations which are secured as to both principal and interest by (a) the full faith and credit of the municipality, (b) a pledge of revenues to be derived from sewerage system use charges or (c) a pledge of revenues to be derived from sewerage system connection or use charges or benefit assessments or both and also by the full faith and credit of the municipality. Any such pledge of revenues shall be valid and binding from the time the pledge is made. The revenues so pledged and thereafter received by the municipality shall immediately be subject to the lien of such pledge without any physical delivery thereof or further act. The lien of any such pledge shall be valid and binding against all parties having claims of any kind against the municipality, irrespective of whether such parties have actual or constructive notice of such lien. The resolution, trust indenture or agreement by which a pledge is created shall be filed with the clerk of the municipality or, in the case of a metropolitan district, in the office of the district clerk. Bonds may be issued by a municipality pursuant to this section for the purposes of refunding bonds previously issued by the municipality pursuant to this chapter, any other provision of the general statutes or any special act. The body having power to authorize such bonds, notes or other obligations shall determine the maximum authorized amount of such bonds, notes or other obligations and may determine or may authorize an officer or board or commission of the municipality to determine the form of such bonds, notes or other obligations, their date, the dates of principal and interest payments, terms of redemption, the manner of issuing such bonds, notes or other obligations and by whom such bonds, notes or other obligations shall be signed or countersigned and, except as otherwise provided herein, all other particulars thereof. Such body or the legislative body of the municipality, if different, may determine the rate or rates of interest for each issue of bonds, notes or other obligations or may provide that the rate or rates of interest shall be determined by an officer or board or commission of the municipality or that such officer, board or commission shall provide for the method or manner of determining such rate or rates or time or times at which interest is payable. Bonds may be coupon or registered bonds. If coupon bonds, they may be registrable as to principal only or as to both principal and interest. Any premium received for sale of bonds, notes or other obligations, less the cost of preparing, issuing and marketing them, may be used for the purposes for which such bonds, notes or other obligations were issued, including capitalized interest, and if not so used, shall be applied to the payment of the principal of the first bonds, notes or other obligations of that particular issue to mature, and contributions from other sources for payment of such bonds, notes or other obligations shall be reduced correspondingly.
