Cultural Water Demand in the Cienega Creek 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 3.3-7.  Effluent generation including facility ownership, location, population served and not served, volume treated, disposal method and treatment level is shown on Table 3.3-8.  Figure 3.3-10 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 3.0.7.  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 Demand

  • Refer to Table 3.3-7 and Figure 3.3-10.
  • Population in this basin is small but has more than doubled since 1980, increasing from 1,695 in 1980 to 4,355 in 2000.  

  • Overall groundwater pumping is estimated to be comparable to historic pumping with an annual average of about 1,400 AFA from 2001-2005.

  • All water use in this basin is groundwater, there are no recorded surface water diversions.

  • Most concentrations of municipal and industrial demand are either around Patagonia or along Interstate 10 along the Cochise County line.

  • Both municipal and industrial groundwater demand has remained fairly constant since 1991, with municipal demand about 550 AFA and industrial demand less than 300 AFA.

  • Agricultural demand has also remained relatively constant since 1992 with less than 500 AFA.  The only agricultural demand center shown on the map is located along Highway 82 in T21S, R16E.

  • In addition to the agricultural demand center shown on the map there are approximately 170 acres of vineyards in this basin.  Most vineyards are located in the Elgin area and all are irrigated with groundwater.

  • As of 2005 there were 1,874 registered wells with a pumping capacity of less than or equal to 35 gpm and 169 wells with a pumping capacity of more than 35 gpm.

Effluent Generation

  • Refer to Table 3.3-8.
  • There is one wastewater treatment facility, the Patagonia Wastewater Treatment Facility, located at Patagonia.
  • 945 people are served by this facility.
  • 73 acre-feet of effluent per year is generated by the facility and discharged into Sonoita Creek.
