NR 852.03 Note(b) Includes any collection or pretreatment storage facilities not under the control of the water supplier for the public water system, which are used primarily in connection with the system.
NR 852.03 Note(c) Does not include any “special irrigation district.”
NR 852.03 NoteNote: The definition of public water system in this chapter is broader and includes more water systems than those governed by the public service commission under its definition of a public utility in ch. 196, Stats. NR 852.03(23)(23) “Retrofit or retrofitting” means to modify or replace existing fixtures, appliances or equipment that is already in service. NR 852.03(24)(24) “System losses” means the difference between the volume of water entering the distribution system and the volume of water that is sold or otherwise authorized for system uses. NR 852.03(25)(25) “Water conservation and efficiency measures” or “CEMs” means structural or non-structural measures, practices, techniques or devices employed to reduce water use, or increase water reuse or water use efficiency. NR 852.03 NoteNote: Section 281.346 (1) (wm), Stats., defines “water loss” to mean “the amount of water that is withheld from or not returned to the basin from which it is withdrawn as a result of a diversion or consumptive use or both.” NR 852.03(27)(27) “Water reuse” means the collection and adequate treatment of clear water, storm water or other wastewater for subsequent use in toilet flushing, irrigation, or other processes that do not require water to meet drinking water quality standards. NR 852.03(28)(28) “Water use audit” means an examination of water use and reuse data that tracks the flow of water in the system from the point of withdrawal or, if the water is provided to the water supply system through a third party, the point of entry into the system, through any treatment and distribution to the end use. The water use audit assesses the quantitative efficiency of a water supply system, and evaluates impacts to water resources and operational and financial aspects of the system, and identifies and quantifies system losses. NR 852.03 NoteNote: The water use audit for a public water supply water use sector includes tracking the water up to the customer service connection.
NR 852.03(29)(29) “Water use intensity” means a measure of water use per unit production, sales unit, or customer served. NR 852.03(30)(30) “Water use sector” means one of the following types of water use sectors: commercial and institutional, industrial, irrigation, livestock, other, power production, or public water supply. NR 852.03 NoteNote: Section 281.346 (1) (y), Stats., defines “withdraw” to mean “to take water from surface water or groundwater.” NR 852.03 NoteNote: Section 281.346 (1) (z), Stats., defines “withdrawal” to mean “the taking of water from surface water or groundwater, including the taking of surface water or groundwater for the purpose of bottling the water.” NR 852.03 HistoryHistory: CR 10-060: cr.
