(Prior Code, § 13.16.020) Penalty, see § 53.99
(A) All costs and expenses incident to the installation and connection of the building sewer shall be borne by the owner. The owner shall indemnify the municipality from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
(B) 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 constructed to the rear building through an adjoining alley, court, yard, or driveway; the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer. Under exceptional circumstances, the Superintendent may waive the provisions of this section.
(C) Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the Superintendent, to meet all requirements of this chapter.
(D) The building sewer shall be of a suitable material approved by the Superintendent. Joints shall be tight and waterproof. If installed in filled or unstable ground, the building sewer shall be 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 Superintendent.
(E) The size and slope of the building sewer shall be subject to the approval of the Superintendent, but in no event shall the diameter be less than four inches. The slope of such four-inch pipe shall not be less than one-eighth inch per foot. It shall be required that the wye connection and building drain shall be uncovered and the differential elevation be determined before construction is begun. Where practicable, the building connection shall be laid on a uniform grade between these two points.
(F) 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 uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with properly curved pipe and fittings.
(G) In all buildings in which any building drain is too low to permit gravity flow to the municipal sewer, sanitary sewage carried by such drain shall be lifted by approved artificial means and discharged to the building sewer.
(H) All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the Superintendent. Pipe laying and backfill shall be performed in accordance with ASTM Specification C12-19 except that no backfill shall be placed until the work has been inspected.
(I) All joints and connections shall be made gas-tight and watertight. Cast iron pipe joints shall be firmly packed with oakum or hemp and filled with molten lead, Federal Specification QQ-L-156, not less than one inch deep. Lead shall be run in one pouring and caulked 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 and metals shall be made with approved hot-pouring jointing material. Material for hot-poured joints shall not soften sufficiently to destroy the effectiveness of the joint when subjected to a temperature of 160°F nor be soluble in any of the wastes carried by the drainage system. The joint shall first be caulked tight with jute, hemp, or similar approved material. Other jointing materials and methods may be used only by approval of the Superintendent.
(J) The connection for the building sewer into the municipal sewer shall be made at the “Y” branch if such branch is available at a suitable location. If the public sewer is 12 inches in diameter or less and no properly located “Y” branch is available, the owner shall, at his or her expense, install a “Y” branch in the municipal sewer at the location specified by the Superintendent.
(K) The applicant for the building sewer permit shall notify the Superintendent when the building sewer is ready for inspection and connection to the municipal sewer. The connection shall be made under the supervision of the Superintendent or his or her representative.
(L) All excavations for building sewer installations shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways, and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the municipality.

(d) Any garbage that has not been properly shredded;
(e) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, leathers, tar, plastics, wood, paunch, manure, or any other solid of viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage system;
(f) Any waters or wastes containing a toxic or poisonous substance in sufficient quantity to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, or create any hazard in the receiving waters of the sewage treatment plant;
(g) Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant;
(h) Any noxious or malodorous gas or substance capable of creating a public nuisance;
(i) Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances to such degree that any such material received in the composite wastewater at the wastewater treatment works exceeds the limits established by the Public Works Director for such materials;
(j) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Director of Public Works in compliance with applicable state or federal regulations;

(4) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of the liquid wastes containing grease in excessive amounts or any inflammable wastes, sand, and other harmful ingredients; except, such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent and shall be located as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight, and equipped with easily removable covers which when bolted in place shall be gas-tight and watertight.
(5) Where installed, all grease, oil, and sand interceptors shall be maintained by the owner, at his or her expense, in continuously efficient operation at all times.
(6) Failure by the owner to properly clean and maintain interceptors shall be considered sufficient cause for the Director to disconnect the industrial user from the wastewater facilities or to direct that the industrial user discontinue discharging to the wastewater facilities or for punitive actions as provided for in this chapter.
(Prior Code, § 13.16.050)
(B) Discharge of waste into public sewers.
(1) If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain objectionable or abnormal characteristics enumerated in division (A)(3) above and which, in the judgment of the Public Works Director, may have a deleterious effect upon the wastewater facilities, processes, equipment, or receiving waters otherwise create a hazard to life or constitute a public nuisance, the Public Works Director may, with the City Engineer:
(a) Reject the wastes;
(b) Require pretreatment to an acceptable condition for discharging to the public sewers;
(c) Require control over the quantities and rates of discharge; and/or
(d) Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of this chapter.
