All rain water and waste water, not allowed to be discharged into the sanitary sewer, which flows over or on any sidewalk or street through drains, gutters, pipes or otherwise from any property abutting thereon, in which street a storm water sewer is laid, shall be connected and discharged into such sewer by the owner of the property within twenty days after receipt of notice to do so from the city engineer, acting on authority from the board of aldermen, by laying a service sewer pipe from the property to the curb of any such street at his expense, under the supervision of the city engineer, and connecting the same to the drain pipe leading from the main sewer to the curb. In the event there is no drain pipe leading from the main sewer to the curb then the city shall lay such pipe at its own expense, but the owner shall be required to pay the tappage fee provided in section 20-12. The owner, at his own expense, shall within ten days after the connection is made, restore the sidewalk to as good condition as it was before the excavation was made. In the event the owner shall fail or refuse to lay the sewer and make the connection above specified the same may be done by the city engineer and the cost thereof charged against the owner of the property and collected by suit before a justice of the peace or in the circuit court for Frederick County, according to the amount involved. (Code 1953, § 16.7.)
