Moneys in the Sewage Works Improvement Fund shall be transferred to the Sewage Works Sinking Fund if necessary to prevent a default in the payment of principal and interest on the then-outstanding bonds or, if necessary, to eliminate any deficiencies in credits to or minimum balance in the debt service reserve account of the Sewage Works Sinking Fund.
