WATER CASA RELEASES INTERIOR-EXTERIOR WATER USE DATA

For the past nine years, Water CASA has been gathering exterior and interior water use data from 27 homes in Tucson.  This is part of an ongoing, long-term monitoring of actual water usage by the residents. Funded a decade ago by the U.S Bureau of Reclamation, this is a partnering study with Water CASA, the Bureau, Flowing Wells Irrigation District, and Genessee Corp, the original homebuilder.

 

Initial findings are reflected in the accompanying chart and indicate:

Average percent of outdoor water use – 20%

Variation in percent of outdoor water use – high: 27%, low: 15%

Average GPCD for these homes – 75

Variation in GPCD – high: 87, low: 66

 

Water CASA will continue to monitor and report the water use data as they are generated.
