Recycled water is an important water resource today and for the future. Tucson Water uses some of its recycled water to produce reclaimed water, which is specially treated for applications such as irrigation, dust control, fire fighting, and industrial uses. Reclaimed water is excellent for the irrigation of turf, ornamental landscaping, food crops, orchards, and vineyards. The nitrogen and phosphorus in the water provide fertilizer for plants and grass.
Reclaimed water is not treated to be used for drinking or bathing. If you come into contact with reclaimed water, wash with soap and water from a drinking water faucet, If you or you child have consumed reclaimed water, it is unlikely to cause ill effects. However, if you or your child should get sick after consuming this water, contact your medical provider and tell her/him that reclaimed water was ingested. She/he will be able to determine if the illness is related to the water.
The reclaimed water Tucson Water provides to our customers is, like all of the water we deliver, regulated by the Arizona Department of Environmental Quality (ADEQ). The reclaimed water delivered by Tucson Water is rated as Class A by ADEQ.
