Kan. Stat. § 12-2705
The costs of providing a common supply of water may be paid from any moneys on hand or available for such purpose or may be financed by the issuance and sale of general obligation bonds or revenue bonds by each of the contracting municipalities in the amount necessary to pay the proportionate share of each such contracting municipality, as such shares shall be fixed pursuant to contract. In the event that the acquisition and development of a common water supply and the construction of a waterworks system shall be effected by the individual action of one of the contracting municipalities or by the individual action of one of the contracting corporations, it shall be lawful for any of the other contracting municipalities or corporations to make a lump-sum payment to such contracting municipality or corporation either from moneys on hand and available for such purpose or, in the case of the contracting municipalities, from moneys received from the issuance and sale of general obligation bonds or revenue bonds, or from tax levies made to meet installment payments to cover its contributions to such cost over the period of the life of any bonds so issued by the municipality acquiring or constructing such a waterworks system.
Nothing herein contained shall prevent the purchase or condemnation of existing sources of water supply, waterworks systems, or portions thereof, necessary for the purposes of the joint project anywhere in the state of Kansas, but there shall be no power to condemn property, the legal title of which is vested in the state of Kansas or any political subdivision thereof, unless the state or the governing body of such political subdivision shall consent thereto. In the event that any source of water supply, waterworks system or portion thereof owned by one of the contracting municipalities or corporations is acquired for the purpose of common supply and joint waterworks system, such municipality or corporation may be allowed a credit against its share of the cost equal to the agreed value of the assets so acquired.
