Cultural Water Demand in the Salt River Basin

Cultural water demand data including population, number of wells and the average well pumpage and surface water diversions by the municipal, industrial and agricultural sectors are shown in Table 5.2-8.  Effluent generation including facility ownership, location, population served and not served, volume treated, disposal method and treatment level is shown in Table 5.2-9.  Figure 5.2-11 shows the location of demand centers.  A description of cultural water demand data sources and methods is found in Volume 1, Appendix A.  More detailed information on cultural water demand is found in Section 5.0.7.  For information on gpcd and annual water demand by individual community water systems in this basin see ADWR's Community Water System Program annual water use reporting summary.

Cultural Water Demands

  • Refer to Table 5.2-8 and Figure 5.2-11.

  • Population in this basin has increased from 27,318 in 1980 to 29,057 in 2000.

  • Total groundwater use has decreased in this basin since 1971, from an average of 20,000 AFA from 1971-1975 to an average of 12,600 AFA in 2001-2005.

  • From 1991-2005 municipal groundwater use averaged 4,000 AFA.

  • Groundwater use for industrial purposes has decreased from 10,500 AFA during 1991-1995 to 8,100 AFA in 2001-2005.

  • Groundwater use for irrigation occurs on non-reservation lands and has remained constant at less than 1,000 AFA during 1991-2005.

  • Information on surface water diversions is not available from 1971-1990.  Surface water diversions for both municipal and irrigation uses are assumed to have remained constant from 1991-2005. Municipal use averaged less than 300 AFA and irrigation use averaged 6,400 AFA.

  • Surface water diversions for industrial use have decreased from an average of 6,300 AFA during 1991-1995 to 4,900 AFA in 2001-2005.

  • Municipal and industrial demand is found in the Globe – Miami area, around Young and near Fort Apache and Whiteriver on the Fort Apache Indian Reservation.

  • There are three large copper mines, Pinto Valley, Carlotta and Miami Mine, and two small mines or quarries located in the vicinity of Miami.  Not all mines are currently in production.

  • As of 2005 there were 1,593 registered wells with a pumping capacity of less than or equal to 35 gpm and 412 wells with a pumping capacity of more than 35 gpm.

Effluent Generation

  • Refer to Table 5.2-9.

  • There are twelve wastewater treatment facilities in this basin.

  • Information on population served was available for seven facilities and information on effluent generation was available for six facilities.  These facilities serve over 18,000 people and generate over 2,600 acre-feet of effluent per year.

  • Of the seven facilities with information on the effluent disposal method: two discharge to evaporation ponds; two discharge for irrigation; one facility discharges to the Globe WWTF and two discharge into a watercourse.
