No person having obtained a permit from the Board shall construct, alter, or repair any house connection sewer or any portion of any house connection sewer, or makes a connection to any public sewer, or house connection sewer, pursuant to any such permit, at any place other than that designated thereon, or fail, refuse or neglect to comply with any such requirement contained or referred to in this section.
At all times, while the work under any such permit is in progress, the original of such permit must be kept at the place of the work and must, on demand be exhibited to the Board or to any of its inspectors, agents or representatives, or to any police officer.
(a) In those streets and alleys included in that portion of this City, designated by Chapter 8 of this Code as the Central Traffic District, when an excavation is commenced, the making of the excavation, the work to be done therein and the refilling of the excavation, shall be prosecuted diligently and continuously until completed, so as not to obstruct the street or other public place or travel thereon, more than is actually necessary.
(b) The construction of all house connection sewers, and all repairs to such house connection sewers, shall be as follows:
1. All pipe shall be clay, cement, cast iron, ABS and PVC plastic pipe or asbestos cement and have a minimum internal diameter of six inches. (Amended by Ord. No. 152,157, Eff. 5/13/79)
2. House connection sewers in easements over private property shall be constructed of only clay pipe with flexible joints, ABS and PVC plastic pipe or cast iron pipe, and may have an internal diameter of four or six inches. (Amended by Ord. No. 152,157, Eff. 5/13/79)
3. Upon proper application to the Board, the Board may permit the increase in the internal diameter of house connection sewers to not more than two inches less than the internal diameter of the public sewer to which it is connected, if such increased diameter is in accordance with good engineering practice.
4. The quality of the pipe, the type of joint and other materials used, the manner of constructing house connection sewers, the backfilling of the trench, except where specifically provided for herein, or by the Board, shall be the same as is required by the latest specifications and standard plans for the construction of sanitary sewers in this City.
(c) Whenever, in connection with the construction or repair of a sewer connection, a hazardous excavation must be made or an excavation is to be made by tunneling under the surface of a street or alley, the Board may adopt such regulations and require such special inspections as it may deem necessary. The cost of such special inspection shall be estimated by the Board and paid as outlined in Section 64.15.
(d) All house connection sewers, unless otherwise authorized by the Board, shall be laid on a uniform grade of not less than two per cent, with a depth, measured to the invert, at the property line, of not less than four feet below the top of the existing curb or proposed curb at the nearest point. If there is no existing or proposed curb, then such house connection sewers shall be laid on a uniform grade of not less than two per cent, with a depth, measured to the invert, not less than four feet below the surface of the roadway, sidewalk or alley at the property line, unless a greater depth is required to serve such property.
(f) Where a building is on or immediately adjacent to the property line, to which a sewer connection must be constructed, and an existing house sewer from said building ends at such property line at a depth of less than the depth required in this section for the upper end of a house connection sewer to be constructed to such property line; or where an earth bank over 4 feet in height exists adjacent to the curb line or property line, the Board shall adopt such regulations, for the construction of that portion of the house connection sewer between the curb line and property line, if in a street, and between the main sewer and the property line, if in an alley, walk or other public place improved or to be improved without a curb, which will meet such conditions better than the method of construction herein prescribed.
Where a main sewer exceeds 14 feet in depth the manner of constructing a house connection sewer from such a sewer shall be regulated by the Board.
(g) (Amended by Ord. No. 142,123, Eff. 7/31/71.) Persons making an excavation in any street or sidewalk for any of the purposes mentioned in Sections 64.12 to 64.22 inclusive, must maintain free access to all fire hydrants and water gates. All materials excavated shall be laid compactly along the side of the trench and kept trimmed up so as to cause as little inconvenience as possible to public travel. If any excavation is made across any street or alley, at least one safe crossing must be maintained at all times for vehicles and pedestrians. Where required to keep traffic lanes and sidewalk passageways clear, tight board fences shall be used to hold excavated material. All gutters must be maintained free and unobstructed for the full depth of the adjacent curb and for at least one (1) foot in width from the face of such curb at the gutter line. All work shall be performed in accordance with the latest adopted manual entitled “Work Area Traffic Control”, the latest adopted “Standard Specifications for Public Works Construction”, any required plans and special specifications and shall be performed to the satisfaction of the Board.
If the warning signs, lights and devices required under this section are not promptly provided, the Board may provide them; the cost of such work performed by the Board may be billed to the permittee.
(h) Any excavation made for the purpose of making a house connection to a sewer shall be refilled in the manner required by this article within three days after inspection of the pipe by the Board, or within three days after the date of the completion of the excavation if no work is done therein. Nothing in this article contained shall be construed to allow a longer period of time therefor.
The top surface of the backfill shall conform closely enough to the level of the adjoining street or sidewalk surface and shall be compacted so that it is hard enough and smooth enough to be safe for pedestrian travel over it as well as for vehicular traffic to pass safely over it at a legal rate of speed. The permittee shall maintain the surface of the backfill in a condition safe for pedestrian and vehicular traffic until the said surface has been repaired by the Board, and said permittee shall be responsible for all accidents which may occur due to pedestrians traveling over or upon the site of the excavation as well as vehicles crossing said site at a legal rate of speed, until said surface has been so repaired. (Amended by Ord. No. 142,123, Eff. 7/31/71.)
If it is impracticable to maintain the surface of the backfill in safe condition for pedestrian travel or vehicular traffic, subject to concurrence by the inspector, then the permittee shall maintain barriers and lights around it in accordance with Subsection (g) hereof until the sidewalk and street pavements have been repaired. (Added by Ord. No. 142,123, Eff. 7/31/71.)
(i) The street surface excavated or damaged shall be replaced by the Board, and the cost thereof shall be recovered by the Board in accordance with the provisions of Section 62.05 of this Code. (Amended by Ord. No. 121,900, Eff. 6/4/62.)
(j) In all cases where the public records of a public sewer, or house connection sewer, do not correctly represent the existing condition of or conditions surrounding such sewer, or where, in the opinion of the Board, the physical conditions are such that strict compliance with the provisions of Section 64.12 to Section 64.22, inclusive, if unnecessary or unreasonable, the Board is granted the power to make modifications for individual cases, and determine the procedure to be followed, and its decision shall be final.
(k) No person shall connect a 4-inch house sewer to a 6-inch house connection sewer without first installing a 6-inch by 4-inch by 4-inch increaser tee on the end of the 6-inch house connection sewer, or a six-inch by 4-inch increaser followed by a 4-inch by 4-inch by 4-inch tee branch.
