B. In either case, the owner or his agent shall make application on a special form furnished by the city. The permit application shall be supplemented by any plans, specifications, or other information considered pertinent in the judgment of the public works director. A permit and inspection fee of $20.00 for a residential or commercial building sewer permit and $20.00 for an industrial building sewer permit shall be paid to the city at the time the application is filed. (Ord. 1429 § 2, 1995).

All costs and expense incidental to the installation and connection of the building sewer shall be borne by the owner or applicant of the premises in question. The owner shall indemnify the city against any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer. (Ord. 1429 § 2, 1995).

13.16.040 Separate sewer for each building – Exception.

A separate and independent building sewer shall be provided for every building; except, that 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. (Ord. 1429 § 2, 1995).

13.16.050 Use of old sewers.

Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the public works director, to meet all requirements of this title. Said testing shall be at the expense of the owner. (Ord. 2009-7 § 2; Ord. 1429 § 2, 1995).

13.16.060 Specifications.

The size, slope, alignment, materials of construction of a side sewer and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling the trench, shall all conform to the requirements of the building and plumbing code or other applicable rules and regulations of the resolutions of the city. In the absence of code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the latest version of the Standard Specifications for Road, Bridge and Municipal Construction (developed by the Washington State Department of Transportation and the Washington State Chapter of the American Public Works Association), the American Society of Testing Materials, and the Water Environment Federation Manual of Practice No. 9 shall apply. (Ord. 1429 § 2, 1995).

13.16.070 Size and slope.

The size and slope of the building sewer shall be subject to the approval of the public works director, but in no event shall the diameter be less than is provided by the Uniform Plumbing Code described in this section. (Ord. 1429 § 2, 1995).

13.16.080 Elevation, location, depth, alignment and changes in direction.

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 in so far as possible. Changes in direction shall be made with properly curved pipe and fittings. (Ord. 1429 § 2, 1995).

13.16.090 Artificial means required where gravity flow not possible.

In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sewage carried by such drain shall be lifted by approved artificial means and discharged to the building sewer. (Ord. 1429 § 2, 1995).

13.16.100 Excavation of trenches and backfill.

All excavation required for the installation of a building sewer shall be open trench work, unless otherwise approved by the public works director. Pipe laying and backfill shall all conform to the requirements of the building and plumbing code or other applicable rules and regulations of the resolutions of the city. In the absence of code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the latest version of the Standard Specifications for Road, Bridge and Municipal Construction (developed by the Washington State Department of Transportation and the Washington State Chapter of the American Public Works Association), the American Society of Testing Materials, and the Water Environment Federation Manual of Practice No. 9 shall apply; except, that no backfill shall be placed until the work has been inspected. (Ord. 1429 § 2, 1995).

13.16.110 Joints and connections.

B. The connection of the side sewer into the public sewer shall conform to the requirements of the building and plumbing code or other applicable rules and regulations of the city of the procedures set forth in appropriate specifications of the American Society of Testing Materials and the Water Environment Federation Manual of Practice No. 9.

C. All joints in vitrified clay pipe, or other approved nonmetallic pipe or between such pipe and metals, shall be made in a manner approved by the public works director.

D. Other jointing materials and methods may be used only by approval of the public works director. (Ord. 1429 § 2, 1995).

13.16.120 Connection to public sewer – Construction specifications.

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. If the public sewer is 12 inches in diameter or less, and no properly located Y branch is available, the owner shall at his expense install a Y branch in the public sewer at the location specified by the public works director. Where the public sewer is greater than 12 inches in diameter, and no properly located Y branch is available, a neat hole may be cut into the public sewer, with entry in the downstream direction at an angle of about 45 degrees. A 45-degree ell may be used to make such connection, with the spigot end cut so as not to extend past the inner surface of the public sewer. The invert of the building sewer at the point of connection shall be at the same or at a higher elevation than the invert of the public sewer. A smooth, neat joint shall be made, and the connection made secure and watertight by encasement in concrete. Special fittings may be used for the connection only when approved by the public works director. (Ord. 1429 § 2, 1995).

13.16.130 Connection to public sewer – Notice of readiness and supervision.

The applicant for the building sewer permit shall notify the public works director when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the public works director or his representative. (Ord. 2009-7 § 3; Ord. 1429 § 2, 1995).

13.16.140 Barricades, lights and restoration – Indemnification of city.

A. All excavations for building sewer installation shall be guarded with barricades and lights and such other precautions as are reasonably adequate to protect the public from accident and injury. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the city.

B. A performance bond or deposit in an amount equal to 110 percent of the estimated cost of work performed within the public right-of-way or utility easements, as approved by the public works director, but in no event less than $500.00, shall be furnished and deposited with the city to indemnify the city against any loss, damage, or liability in connection with such sewer work. (Ord. 1429 § 2, 1995).

13.16.150 Inappropriate connections prohibited.

No person shall make connection of roof downspouts, exterior foundation drains, areaway drains, or other sources of surface runoff or ground water to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer. (Ord. 1429 § 2, 1995).
