In Wisconsin, centralized non-potable reuse The use of recycled water for centralized non-potable reuse where the water does not derive from the same site where it is to be reused. Can include, but is not limited to, toilet flushing, dust control, soil compaction, fire protection, commercial laundries, vehicle washing, street cleaning, snowmaking, and other similar uses. Excludes on-site non-potable water reuse and the use of recycled water for agriculture or landscaping. applications include vehicle washing, air conditioning and making concrete, among others. The source of water treated municipal wastewater Treated wastewater effluent discharged from a centralized wastewater treatment plant of any size. Other terms referring to this source of water include domestic wastewater, treated wastewater effluent, reclaimed water, and treated sewage. is specified by the state as municipal wastewater. The write-up uses state terms when discussing sources or uses of water that may differ from the Regulations and End-Use Specifications Explorer's (REUSExplorer's) terms.
Technical basis
Wisconsin approves the use of recycled water for centralized non-potable reuse applications including, but not limited to, vehicle and clothes washing, air conditioning, soil compaction, dust control and toilet and urinal flushing (Wis. Admin. Code Trans. § 382.70). All applicable provisions of the Clean Water Act (CWA) (33 U.S.C. §§ 1251 et seq.), including its implementing regulations, must be met in addition to any state water quality standards. Performance standards are applied for the removal of chemical contaminants for centralized non-potable reuse applications. The technical basis for the removal of chemicals is not specified.
Applications of centralized non-potable reuse approved for use in Wisconsin
Wis. Admin. Code Trans. § 382.70 defines the following approved centralized non-potable reuse applications:
- Vehicle washing
- Clothes washing
- Air conditioning
- Soil compaction and dust control
- Washing aggregate
- Making concrete
- Toilet and urinal flushing
Water reuse category/type
Wisconsin does not assign recycled water used for centralized non-potable reuse applications to a category or class.
