Sections:
12.03.010 Sewer service required.
12.03.020 Sewer line extensions.
12.03.030 Sewer line location.
12.03.080 Side sewer maximum length.
12.03.090 Gravity flow required.
12.03.100 Design approval and adjustment.
12.03.010 Sewer service required.
All new lots and development shall be served by a sanitary sewer line located adjacent to the lot or development site. (Ord. 98-64 § 1 (part), 1998).
12.03.020 Sewer line extensions.
Sewer lines shall be extended to the point where the adjoining property owner’s responsibility for further extension begins. This typically requires extension across the street or easement frontage of the developing property. In some cases it will require dedication of an easement and a line extension across the property or extension along two or more sides of the developing property. Extensions will be consistent with and implement the city’s adopted sewer comprehensive plan. (Ord. 98-64 § 1 (part), 1998).
12.03.030 Sewer line location.
Sewer lines shall be located in streets to serve abutting properties. When necessary, sewer lines may be located within public easements. Sewer mains located in streets will be offset from the street centerline by six feet and manholes shall not be located within a vehicle tire path. Sewer lines located in easements shall generally be located in the center of the easement, but may, with the approval of the city engineer, be offset to accommodate the installation of other utilities or to satisfy special circumstances. (Ord. 2001-13 § 13, 2001: Ord. 98-64 § 1 (part), 1998).
12.03.040 Minimum line size.
The minimum size for public sewer lines is eight inches in diameter. (Ord. 98-64 § 1 (part), 1998).
12.03.050 Line termination.
Sewer lines shall be terminated with a flush-end (clean-out) or a manhole as directed by the city engineer. Manholes will generally be used when extension of the sewer line is anticipated and manhole spacing will be appropriate for the future. (Ord. 98-64 § 1 (part), 1998).
12.03.060 Manholes required.
Manholes shall be installed at intervals of no greater than three hundred fifty feet and at all vertical and horizontal angle points. (Ord. 2001-13 § 14, 2001: Ord. 98-64 § 1 (part), 1998).
12.03.070 Side sewer service.
Each building containing sanitary facilities shall be served by a separate private side sewer line from a public main, except as provided for in YMC 7.65.050(D). Branched side sewers serving multiple buildings and properties shall not be permitted, except as provided for in YMC 7.65.050(D). Single side sewers serving multi-unit buildings are permitted. (Ord. 2023-016 § 3, 2023; Ord. 2001-13 § 15, 2001: Ord. 98-64 § 1 (part), 1998).
12.03.080 Side sewer maximum length.
The maximum side sewer length within public right-of-way shall be one hundred feet unless otherwise approved by the city engineer. (Ord. 2001-13 § 16, 2001: Ord. 98-64 § 1 (part), 1998).
12.03.090 Gravity flow required.
Sewer lines shall be designed for gravity flow operation. Lift stations and force mains (pressurized lines) shall be limited to those locations and circumstances where they are consistent with the comprehensive sewer plan and are the preferable short-term solution to service of the development site and other properties in the vicinity. (Ord. 2001-13 § 17, 2001: Ord. 98-64 § 1 (part), 1998).
12.03.100 Design approval and adjustment.
The engineering design of sewer facilities is subject to approval by the city engineer. The city engineer may, in his discretion, adjust these standards as necessary to facilitate installation of sewer facilities, in cooperation with the wastewater division manager. (Ord. 2001-13 § 18, 2001: Ord. 98-64 § 1 (part), 1998).
