The following requirements shall apply to existing house sewers:

A. If the construction of a new house sewer on a lot is to include any portion of an existing house sewer on such lot, such construction shall be included and accepted only when it meets all the requirements for new house sewers and is of a material acceptable to the superintendent or city engineer.

B. When it is found necessary to replace any portion of an existing house sewer between the street curb and lot line, all that portion of the house sewer between these limits shall be replaced to meet the requirements for new house sewers.

C. When it is found necessary to replace any portion of an existing house sewer between the curb and public sewer, all that portion of the house sewer between these limits shall be replaced to meet the requirements for new house sewers.

(Ord. 4170 § 2.03, 1950)

All house sewers which are to be connected to a trunk sewer shall include a running trap, the type and location of which shall meet the approval of the city engineer and chief engineer.

(Ord. 4170 § 2.04, 1950)

All house sewers shall be laid by the most direct route feasible, free of pinched joints, changes of grade, or unnecessary bends or fittings.

(Ord. 4170 § 2.05, 1950)

All excavations shall have sufficient width to allow proper workmanship and permit adequate inspection and shall be supported in the manner set forth in the rules, orders and regulations prescribed by the Industrial Accident Commission of the state. Sheet piling and other timbers shall be withdrawn in such a manner as to prevent caving of the walls of the excavation or disturbance of the sewer pipe.

(Ord. 4170 § 2.06, 1950)

A. The Y or T saddle shall be installed by cutting a hole in the main line sewer pipe and fitting the saddle snugly in place with heavy (12 gauge) galvanized asphalt painted iron wire bound around the main line pipe and the flange of the saddle. The Y saddle shall be placed in the side of the main line pipe with the Y branch upward at approximately 45 degrees from the horizontal and so as to direct the flow from the house connection sewer down stream into the main sewer. The T saddle shall be placed in the top of the main line sewer pipe. The T saddle shall be used only for the construction of a chimney pipe.

B. After the saddle is in place, an imbedment of cement concrete shall be placed under and around the main line sewer pipe and saddle as required for a standard chimney pipe in accordance with the standard plan on file in the office of the city engineer. The inside of the joint between pipe and saddle shall be pointed with 1:2 cement mortar.

(Ord. 4170 § 2.07, 1950)

No person shall connect or cause to be connected any sewer which has been, or may hereafter be, constructed in any street, highway, alley, right-of-way, or other public place prior to the dedication and acceptance of such street, alley, right-of-way or other public place by the board on behalf of the public, with any public sewer of the city, unless such sewer first mentioned shall have been laid under the supervision and/or to the satisfaction of the city engineer and in accordance with all provisions of this chapter.

(Ord. 4170 § 2.08, 1950)

A. No connection from any building or other structure shall hereafter be made to any public sewer, if such connection or any portion thereof is in, under or upon any lot other than the lot on which such building or structure is located, except a house court or an auto trailer court.

B. If a lot or parcel of land requiring a sewer connection is so situated that access to the public sewer is not possible except across some other lot or parcel of land, a sewer connection may be placed in a recorded public easement which includes the right to lay and maintain such connection and is appurtenant to the lot or parcel of land to be served by such sewer connection.

C. Each building having separate frontage on a public street on which there is a public sewer must be separately connected to the public sewer.

(Ord. 4170 § 2.09, 1950)

No person shall connect or cause to be connected any cesspool or septic tank to any public sewer or to any house sewer leading thereto.

(Ord. 4170 § 2.10, 1950)

Upon connection of a house sewer to the public sewer, every septic tank, cesspool, seepage hole or dry well which was not constructed of brick or concrete as required by Ordinance No. 3881 as amended, and every dry pit privy hole which has been abandoned and discontinued from use, shall be backfilled solidly with earth to the satisfaction of the superintendent or engineer.

(Ord. 4170 § 2.11, 1950)

In every case where a plumbing outlet or plumbing fixture is installed or located below the elevation of the curb or property line, an approved type of backwater trap or an approved type of backwater sewer valve shall be installed between the outlet and the public sewer in such a manner as to prevent sewage from flowing back or backing up into any such outlet or plumbing fixture. Every such trap or valve shall be installed in the basement, or in a box or manhole of concrete, or cast iron, or other material approved by the superintendent so that it will be readily accessible at all times. The trap or valve shall be placed only in the drain line serving the fixtures that are located below the elevation of the above-mentioned curb or property line and no drainage from fixtures located above this elevation shall pass through such trap or valve.

(Ord. 4170 § 2.12, 1950)

Every interceptor shall be of proper design and of an adequate size to prevent sand, silt, grit, mineral material, petroleum, solvent, grease or oil from entering the sewer. The size and design shall be as approved by the superintendent and city engineer.

(Ord. 4170 § 2.13, 1950)

Every interceptor shall be so constructed and arranged that flowing wastes will not wash out or carry away any of the grease, sand or petroleum solvents previously collected in such interceptor. The city engineer may require screens to be placed in interceptors to prevent rags from entering the public sewer.

(Ord. 4170 § 2.14, 1950)

Existing interceptors which are found upon inspection to be of inadequate size or of improper design shall be revised as directed by the city engineer within 30 days after notice upon penalty of immediate disconnection from the sewer and fined as provided in Section 13.24.170. Notice of inadequate interception facilities shall be given by registered mail and shall be deemed effective as of the 5th day after receipt of said notice.

(Ord. 4170 § 2.15, 1950)

In event a special type of interceptor is required to adequately protect the sewer, a competent engineer shall be retained to fully investigate the processes at the plant and provide adequate facilities for the retention of undesirable wastes by interceptors or other suitable means. The proposed design shall be submitted to the city engineer for his approval prior to installation and connection to the sewer.

(Ord. 4170 § 2.16, 1950)

The city engineer may adopt, in writing, such test requirements as he finds necessary to determine the collecting efficiency of various types and kinds of interceptors and to establish the rate of flow, grease or sand retention capacity or other rating thereof. The city engineer may revise from time to time, as he finds necessary, such test requirements.

(Ord. 4170 § 2.17, 1950)

All industrial liquid waste pretreatment plants, grease interceptors, sand interceptors, sewage treatment plants, sewage pumping plants or ejectors, septic tanks, cesspools, dry wells, dilution chambers and neutralization tanks shall be constructed in accordance with Ordinance No. 3881 (Plumbing Code) unless otherwise provided in this chapter.

(Ord. 4170 § 2.18, 1950)
