Except as delineated in sub. (2)
, this chapter applies to all of the following:
A situation where domestic wastewater is collected and conducted by means of plumbing drain systems and is not conveyed to a wastewater treatment facility regulated by the department of natural resources.
A POWTS where domestic wastewater is treated and dispersed to the subsurface.
A holding tank that is utilized as a POWTS or as part of a POWTS to collect and hold domestic wastewater for transport and treatment elsewhere.
SPS 383.02 Note
Section SPS 382.10 (2) (d)
states that where plumbing fixtures exist in a building which is not connected to a public sewer system, suitable provision shall be made for treating, recycling, dispersing, or holding the wastewater in a manner satisfactory to the department.
SPS 383.02 Note
The department of natural resources is responsible for establishing, administering and enforcing standards relative to domestic wastewater treatment systems which either disperse to the surface or to surface waters. The department of natural resources also establishes effluent limitations and monitoring requirements where the design daily influent wastewater flow to a POWTS exceeds 12,000 gallons per day for the purpose of fulfilling WPDES permit requirements under ch. 283
