. e m. A void vertical breaks in profiles. Use alternate scale for all profile sheets if all of proposed sanitary sewer cannot be shown on anyone profile section for the station run indicated in plan view for that sheet. 6. All construction drawings for new sanitary sewers shall show the proposed location, by stations and offsets, of all service leads, and service connection risers. E. Service Lead Construction for Residential and Commercial Developments 1. Space the location ofservice leads so as to limit the number of service lead taps to the lateral sewer or sewer main. Service leads should be spaced at every other property line between two adjoining residential lots unless there is an odd number of lots. The City reserves the right to direct the engineer to relocate any proposed service lead upon reviewing any submitted plans. A single 6-inch service lead located at the property line between two adjoining residential lots would serve two single-family residences with a wye placed at the end of the service lead. The wyes shall be located at the private property line. a. Near side double sewer service leads shall not exceed 5 feet in length, shall terminate at the property line, and shall be located within the public right-of-way or public easement. b. In cases where the sanitary trunk main is further than 5 feet from edge of the right-of-way, a single 6-inch service shall be run from the sewer main to the edge of the right-of-way whereupon a wye shall be placed as described above in Article 4.02, Section E, Clause I if 2 lots or parcels are to be served. This shall apply to residential sanitary service leads and not to commercial service taps. 2. Any far side service lead of more than 60 feet perpendicular to the street right- of-way shall, at the City's discretion, be treated as a lateral sewer. 3. Service leads for single-family developments should not connect to the manhole, and may be granted approval on a case by case basis. Commercial or industrial service leads expected to discharge more than 5000 gallons-per-day shall discharge directly into a proposed or existing sanitary sewer manhole. Where the flowline of the service lead is 36 inches or greater above the flow line of the manhole, provide a standard drop manhole. a. Service leads shall be provided to serve each lot or parcel within a proposed residential, commercial or industrial development. The detail for a typical near-side and far-side service leads shall be included with the construction drawings. b. Service leads shall be a minimum of 6 inches in diameter where two or more lots or parcels are served. If the perpendicular length of a service lead exceeds 60 feet, the minimum diameter shall be S inches and a manhole shall be utilized for connection to the public sewer. Such Sinch leads may, at the discretion of the City, be reviewed upon submittal of the construction drawings as a lateral sewer line. c. In such cases where a service lead is proposed to run diagonally across the street, prior approval from the City Engineer must be obtained. d. Service leads with a diameter of 6 inches shall utilize full body fittings be they extruded or factory-fabricated for connection to a proposed public sewer or an approved saddle-type connector for connection to an existing public sewer.
