Conn. Gen. Stat. § 22a-442
If federal funds are not available to the municipality at the time of its scheduled construction of a pollution abatement facility, the commissioner shall advance to such municipality, in addition to the state contribution provided for in section 22a-439, that sum of money which would equal the amount of the federal grant, provided the municipality shall agree that any federal contribution thereafter made for the project shall be forwarded to the state as reimbursement for the funds expended under this section. Prior to advancing the federal share, the commissioner shall require the municipality to agree in its project contract with the commissioner to do all that is necessary to qualify for the federal grant. The municipality shall also agree to pay over to the commissioner any installment of a grant received from the federal Water Pollution Control Administration on which the state has made an advance under this section. Said moneys received from the municipality shall be deposited in a sinking fund which is hereby established for payment of the debt service costs of bonds issued under section 22a-446.
