(2) SCOPE. The provisions of
					 this section apply to plumbing systems that supply water to outlets.
Note:
For requirements and specifications

Note:
The department of natural resources
						requires WPDES permits for point source discharges under ch. 283, Stats.
(3) GENERAL REQUIREMENTS. A
					 plumbing system shall supply water that is of a quality that will protect
					 public health and the waters of the state and be suitable for the intended use.
Note:
Refer to s.
						SPS
						382.34 for requirements for wastewater reuse.
(4) MINIMUM REQUIREMENTS.
(a) Except as provided under par. (b), a
					 plumbing system shall supply a quality of water at the outlet or at the
					 termination of the plumbing system that meets or exceeds the minimum
					 requirements as specified in Table 382.70-1.

b Applies only to wastewater
						treatment devices for reuse systems. Other equivalent disinfection methods may
