SPS 382.30(1)(1) Scope. The provisions of this section set forth the requirements for the design and installation of sanitary drain systems, including building drains and building sewers. SPS 382.30 NoteNote: The provisions for storm and clear water drain systems are specified in s. SPS 382.36. SPS 382.30(2)(2) Materials. All sanitary drain systems shall be constructed of approved materials in accordance with ch. SPS 384. SPS 382.30(3)(a)1.1. ‘Fixture.’ The load factor on drain piping shall be computed in terms of drainage fixture unit values specified in Table 382.30–1 for the corresponding listed fixture. SPS 382.30(3)(a)2.2. ‘Devices.’ Drainage fixture unit values for intermittent flow devices not listed in Table 382.30–1 shall be computed on the basis of one fixture unit equalling one gallon per minute of flow. SPS 382.30 NoteNote: Equipment with a timed discharge cycle(s) of 2 minutes or less may be considered as an intermittent flow device.
SPS 382.30(3)(b)(b) Continuous flow devices. Drainage fixtures unit values for continuous flow devices such as pumps, ejectors, air conditioning equipment or similar devices that discharge continuously shall be computed on the basis of 2 fixture units for each one gallon per minute of flow. SPS 382.30(4)(a)1.1.
