Colo. Rev. Stat. § 31-25-515
Before paving in any district in pursuance of this part 5, the governing body may order the owners of the abutting property to connect their several premises with the gas or water mains or with any other utility in the street in front of their several premises. Upon default of any owner for thirty days after such order to make such connections, the municipality may contract for and make the connections at such distance, under such regulations, and in accordance with such specifications as may be prescribed by the governing body. The whole cost of each connection shall be assessed against the property with which the connection is made, and the cost shall be paid upon the completion of the work in one sum. The cost shall be assessed, shall become a lien, and shall be collected in the same manner as is provided in this part 5 for the assessment and collection of the cost of other special improvements. Upon default in the payment of any such assessment, the property shall be sold in like manner and with like effect.
