At any time when the district has no bonds or other obligations outstanding, the board may adopt a resolution, which shall be duly entered upon its minutes, declaring that the district shall be dissolved. Upon the filing for record of a certified copy of the said resolution in the office of the judge of probate of the county in which the district’s certificate of incorporation was filed the district shall thereupon stand dissolved and, in the event it owned any property at the time of its dissolution, the title to all its property shall thereupon pass to and be divided and apportioned among the counties and municipalities in which any part of the service area may be located, or, if it is a supply district, among its authorizing subdivisions, all in such manner and to such extent as may be provided in the district’s certificate of incorporation, as amended; provided, however, that in the absence of a contrary provision in the said certificate of incorporation, as amended, title to real estate and tangible personal property, other than cash, shall vest in the county or municipality, as the case may be, in which the said real estate or tangible personal property is located and the title to cash on hand and in banks, accounts receivable, choses in action, and other intangible property, other than intangible interest in land, shall vest in all of the counties and municipalities in which any part of the service area lies. Each such county and municipality shall have title to said cash and intangible items as a tenant in common thereof, the fractional interest of each such tenant in common in said items being represented by a fraction the numerator of which is an amount equal to the gross revenues derived by the district during its then next preceding complete fiscal year from service rendered in that part of its service area within that county or municipality, as the case may be, and the denominator of which is an amount equal to the gross revenues derived by the district during the same period from services rendered in its entire service area. For the purposes of this section only, real and tangible personal property, other than cash, located and service rendered wholly within a municipality shall not be deemed to be located or rendered, as the case may be, in a county.
