11.45.010 Responsibility and ownership.

The owner of the property served by the side sewer shall construct, pay for, own, and maintain the side sewer. The city shall have right of access to the side sewer for inspection and maintenance purposes. (Ord. 06-271 § 1).

11.45.020 Side sewer – New – Existing – Abandoned.

A new side sewer and building sewer, constructed with new materials, as approved by the city, shall be required for new connections and when modifications are made to an existing side sewer or building sewer; except, that such connection may be made to an existing side sewer and/or building sewer; provided, that said existing side sewer is examined by video camera and shown to be sound and the building sewer, if any, successfully passes a pressure test.

If a side sewer is temporarily abandoned, the building sewer shall be disconnected from the cleanout at the right-of-way line and replaced with an eight-inch nipple and cap. The joints shall be gasketed, the cap blocked, and the cleanout in good condition or replaced.

If a side sewer is permanently abandoned, the side sewer shall be removed and replaced at the sewer main, submain, or lateral tee with a 12-inch nipple and cap. The joints shall be gasketed and the cap blocked. (Ord. 06-271 § 1).

11.45.030 Operation and maintenance requirements – Permission to test.

A. Operation. The owner shall be permitted to own and operate a side sewer in the right-of-way or other easement in conformance with the conditions of the right-of-way use permit. Only wastewater meeting the requirements of Chapter 11.50 EMC shall be permitted to be discharged through such side sewer. Violation of the conditions of said permit may result in its revocation, termination of sewer service, and disconnection of the side sewer as provided in EMC 11.65.030.

B. Maintenance. The owner shall be responsible for the maintenance of the side sewer and shall also keep an as-built record of its location. In the event the side sewer becomes restricted or blocked, it shall be the owner's responsibility to restore service.

C. Inflow and Infiltration. The owner shall maintain the integrity of the side sewer and building sewer and shall permit no connections thereto other than pipes carrying wastewater meeting the requirements of Chapter 11.50 EMC. Pipes that become broken or joints that permit infiltration of groundwater or surface water shall be replaced or repaired. If the city determines that an unacceptable quantity of ground or surface water is being discharged into the city's sewer system from the owner's side sewer, the owner shall be required to eliminate such inflow and/or infiltration.

D. Testing. The owner, as a condition of the connection permit and agreement, shall give the city permission to test the side sewer and private sewers on the owner's property for inflow and infiltration, during normal business hours, seven days following notification. The techniques that may be used for such testing shall be as provided in the connection permit and agreement, the Design and Construction Standards and the Orange Book. (Ord. 06-271 § 1).

11.45.040 Design.

A. All side sewers shall be designed in accordance with the Design and Construction Standards, this title, and the Standard Specifications.

B. The separation between side sewers and water lines shall be as set forth in EMC 11.35.020.

C. The minimum diameter of a side sewer shall be six inches.

D. The six-inch side sewer shall connect to the sewer in a tee in new construction and a saddle if connecting to an existing sewer. The leg of the tee or saddle shall be set at an angle of 45 degrees up from a horizontal plane. The minimum slope of a side sewer shall be one percent.

E. A cleanout shall be installed at the street side of the right-of-way line, at which point the building sewer shall be connected to the side sewer.

F. A check valve shall be required at the connection of the building drain to the building sewer when plumbing fixtures are located in the basement of a building or on any floor less than four feet above the crown of the sewer to which its side sewer is connected, unless otherwise approved by the director.

G. Only one building shall be connected to a side sewer. If there is more than one building on a single lot and it is impracticable to connect both side sewers to the sewer in the street, a sewer lateral shall be extended onto the private property within an easement. The sewer lateral shall terminate in a manhole, except that a cleanout may be used if the lateral is 50 feet or less in length. The sewer lateral must connect to the sewer main or submain at a manhole.

H. Buildings that are accessory to a single-family residence on a single-family lot may share a common connection. If ownership of such buildings is segregated by any action, such as subdivision or condominium, separate connections shall be required for each building so segregated.

I. A side sewer, eight inches or greater in diameter, must connect to the sewer system at a manhole.

J. When a side sewer is constructed prior to the building sewer, the director may permit the construction of up to 20 feet of building sewer with the side sewer to avoid damage to improvements in the right-of-way when the connection is made. (Ord. 06-271 § 1).

11.45.050 Private sewage pumps.

A. Each private pump station shall discharge through its own private, dedicated force main. The private force main shall discharge into a private manhole, located on the owner's property, which shall discharge into the city's sewer in a standard gravity side sewer.

B. A private force main shall be permitted to discharge into a city manhole only when the director finds there is no reasonable alternative. A force main shall not discharge directly into another force main or gravity sewer pipe.

C. When upper floors of a building can drain to the city's sewer in a standard gravity building sewer and side sewer, only plumbing fixtures in those parts of the building that cannot be so drained shall be connected to the private pump station. (Ord. 06-271 § 1).

11.45.060 Permits required.

Side sewer construction and/or connection to the side sewer shall not begin until all of the following permits have been obtained:

A. Connection permit and agreement as described in EMC 11.40.050.

B. Right-of-way use permit for construction.

C. Right-of-way use permit for operation and maintenance of a side sewer. (Ord. 06-271 § 1).

11.45.070 Side sewer contractor.

The side sewer contractor shall be required to have a current and valid Washington State contractor's license and a city of Edgewood business license, and shall supply the city with copies of both and provide the city with documented proof of experience in underground utility construction. A right-of-way use permit shall not be issued for construction of a side sewer unless the contractor can demonstrate such experience and is approved by the director. (Ord. 06-271 § 1).

11.45.080 Bond and insurance required.

A performance bond, insurance, indemnification, and maintenance bond, meeting the requirements as set forth in Chapter 12.06 EMC, shall be required as a condition of issuance of the right-of-way use permit. (Ord. 06-271 § 1).

11.45.090 Construction.

All construction shall be in conformance with the Design and Construction Standards, this title, and the Standard Specifications. (Ord. 06-271 § 1).

11.45.100 Inspection.

Inspection and testing of the side sewer shall be as described in the Design and Construction Standards, and payment for same as set forth in EMC 11.40.110. (Ord. 06-271 § 1).

11.45.110 Restoration.

No connection shall be made until the street, curb, gutter, sidewalk, and landscaping in the right-of-way have been restored as set forth in the Design and Construction Standards, this title, and the Standard Specifications. (Ord. 06-271 § 1).

11.45.120 Record drawings.

The owner shall submit a record drawing, meeting the requirements of the Design and Construction Standards and this title, to the city when construction of the side sewer is complete. The record drawing shall be subject to review and approval of the director. (Ord. 06-271 § 1).
