The owner of all houses, buildings, or properties used for human occupancy, employment, recreation, or other purpose, situated within the city and abutting on any street, alley, or right-of-way in which there is now located a public sanitary sewer of the city, is hereby required at his or her expense to install suitable toilet facilities therein, and to connect such facilities directly with the proper public sewer in accordance with the provisions of this article, within 90 days after date of official notice to do so, provided that said public sewer is within 140 feet of the property line.
(Ordinance 1999-5, sec. 4.01(b), adopted 6/8/99)
No person shall uncover, make any connections with or opening into, use, alter, or disturb any public sewer or appurtenance thereof without first obtaining a written permit from the city.
(Ordinance 1999-5, sec. 4.01(c), adopted 6/8/99)
The connection of the building sewer into the public sewer shall be made at the “Y” branch if such branch is available at a suitable location. Where no properly located “Y” branch is available, the connection shall be made in the manner approved by the utility superintendent and at a location designated by the superintendent.
(Ordinance 1999-5, sec. 4.01(d), adopted 6/8/99)
A separate and independent building sewer shall be provided for every building except where one building stands at the rear of another on an interior lot and no private sewer is available or can be feasibly constructed to the rear building. In such case, the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer.
(Ordinance 1999-5, sec. 4.01(e), adopted 6/8/99)
(a) 
The building sewer shall be constructed of cast iron pipe, ASTM specifications A74-42, or approved equal; vitrified clay sewer pipe, ASTM specifications C13-44T, or approved equal; or an approved plastic pipe. Any plastic pipe to be installed on any building sewer shall not be approved by the city until the owner has furnished descriptive literature and a typical sample section of the plastic pipe proposed for installation to the city for inspection and review. All joints on all pipe installed shall be tight and waterproof. Any part of the building sewer that is located within 10 feet of a water service pipe or city water main shall be constructed of approved cast iron soil pipe with approved joints. No building sewer shall be installed within three feet of existing gas lines. If installed in filled or unstable ground, the building sewer shall be constructed of cast iron soil pipe, except that nonmetallic material may be accepted if laid on a suitable concrete bed or cradle as approved by the city.
(b) 
The size and slope of the building sewer to be installed shall be subject to the approval of the city inspector, but in no event shall the diameter of the pipe be less than four inches. The slope at which a six-inch pipe is to be laid shall be not less than 1/8 inch per foot, and for four-inch pipe not less than 1/4 inch per foot. Any grades for the pipe which are proposed for installation at grades less than those specified shall be approved by the city inspector prior to placement.
(c) 
Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. No building sewer shall be laid parallel to or within three feet of any bearing wall which might thereby be weakened. The depth shall be sufficient to afford protection from frost. The building sewer shall be laid at a uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with approved curved pipe and fittings, including cleanout fittings.
(d) 
At buildings in which the building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such drain shall be lifted by approved artificial means and discharged to the building sewer. The use of any pumping equipment for which cross-connections with a public water supply system are needed is prohibited. The total costs of pumping equipment and pumping equipment operational costs shall be those of the owner.
(e) 
No building sewer shall be laid across a cesspool, septic tank or vault until the cesspool, septic tank or vault has been well cleaned and filled with an approved earth or sand fill, then thoroughly tamped and water settled.

(f) 
All excavation required for the installation of the building sewer shall be open trench work unless otherwise approved by the city. Pipe laying and backfill shall be performed in accordance with ASTM specifications C12-19, except that no backfill shall be placed until the work has been inspected and approved.
(g) 
All joints in the building sewer shall be made watertight. If recommended by the city inspector, a water pressure test shall be made on the completed sewer to insure compliance with this requirement, requiring that the building sewer withstand an internal water pressure of 5 psi without leakage. Cast iron pipe with lead joints shall be firmly packed with oakum or hemp and filled with molten lead, Federal Specifications QQ-L-156, not less than one inch deep. Lead shall be run in one pour and caulked and packed tight. No paint, varnish or other coatings shall be permitted on the jointing material until after the joint has been tested and approved. All joints in vitrified clay pipe shall be the polyurethane-compression type joints, approved by the city inspector. Joints for all plastic pipe used in building sewers shall be the slip type joints or solvent weld type, approved by the city. Joints between any two different types of pipes shall be made with lead, asphaltic jointing materials or concrete, as approved by the city. All joints shall be watertight and constructed to insure minimum root penetration and to the satisfaction of the city.
