NR 110.13(5)(f)(f) Joints for nonpressure pipe. The method of making joints and the materials used shall be included in the specifications and meet the minimum standards in subds. 1. to 5. Sewer joints shall be designed to minimize infiltration and to prevent the entrance of roots. Joint material shall be of such a composition as not to be adversely affected by the sewage.

NR 110.13(5)(f)4.4. Polyvinyl chloride sewer pipe shall be joined by solvent weld joints or by elastomeric joints which have been approved by the department.

NR 110.13(5)(f)5.5. ABS composite sewer pipe shall be joined by solvent weld joints or by type OR mechanical–seal joints meeting the requirements of ASTM D2680-01 (2009).

NR 110.13(5)(g)(g) Pressure sewer pipe and joints. All pressure sewer pipe 10 centimeters (4 inches) or larger shall meet the following minimum requirements:

NR 110.13(5)(g)4.4. Polyvinyl chloride pipe and joints shall meet the requirements of AWWA C900-07 (minimum class 150) or ASTM D2241-09 (minimum class 250). Solvent weld joints may not be used.

NR 110.13(5)(g)5.5. Fiberglass reinforced–polyvinyl chloride composite pipe and joints shall meet the requirements of AWWA C950-07 (minimum class 250). Eight and 10–inch pipe shall have minimum category 3 stiffness as defined in ASTM D2996-01 (2007) e1. Four and 6–inch pipe shall have a minimum category 2 stiffness as defined in ASTM D2996-01 (2007).

NR 110.13(5)(h)(h) Small diameter pressure sewer pipe and joints. All pipe and joints 8 centimeters (3 inches) in diameter or smaller to be used in grinder pumps shall meet the following minimum requirements:

NR 110.13(5)(h)1.1. Polyethylene pipe and joints which meet the requirements of ASTM D2239-03 (minimum class 160) may be approved on a case–by–case basis depending on the expected system pressure relative to the pipe working strength. Solvent weld, butt fusion, or elastomeric joints will be acceptable.

NR 110.13(5)(h)3.3. Polyvinyl chloride pipe and joints shall meet the requirements of ASTM D2241-09 (minimum class 160). Solvent weld or elastomeric joints will be acceptable.

NR 110.13(6)(6) Sanitary sewer overflow structures. Sanitary sewer overflows structures may be provided as measures to manage and mitigate the effects of sanitary sewer overflow discharges that may occur under extreme conditions. Sanitary sewer overflow structures shall be designed in accordance with all the following requirements:

NR 110.13(6)(a)(a) The overflow may be activated either manually or automatically. If automatically activated, a monitoring system shall be provided to detect the initiation time of the overflow and to provide an alarm signal to the sewage collection system operator or other responsible authority.

NR 110.13(6)(b)(b) The overflow structure shall be designed to discharge only those wastewater flows greater than the peak flow conveyance capacity within the sewage collection system.

NR 110.13(6)(c)(c) Equipment shall be provided to measure the flow and, if practicable, sample the wastewater discharged from the structure.

NR 110.13 NoteNote: A department approval of a sanitary sewer overflow structure does not eliminate or alleviate the requirement that prohibits sewage treatment facility overflows in s. NR 210.21.
