Cultural Water Demand in the Douglas 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 3.5-7.  Effluent generation including facility ownership, location, population served and not served, volume treated, disposal method and treatment level is shown on Table 3.5-8.  Figure 3.5-10 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 3.5-7 and Figure 3.5-10.
  • Population increased by an average of 500 people per year between 1980 and 2000. 

  • All water use in this basin is groundwater and over three-fourths of the water demand in this basin is for agriculture.  Total groundwater use decreased significantly in this basin from 1971 to 1990.  From 1990 to 2003, however, total groundwater has increased although not to the same level as in 1971.

  • The highest concentration of municipal and industrial demand is found near Douglas and Pirtleville with smaller centers north of Pirtleville along Highway 191, north of Elfrida and west of Douglas along Highway 80.

  • The majority of the agricultural demand in the basin is in the vicinity of Highway 191 and north of Elfrida.

  • There are large mine facilities, including the Copper Queen Mine and the Paul Spur Quarry located along Highway 80.  There is, however, no recorded industrial water use in this basin after 1990.

  • As of 2005 there were 1,666 registered wells with a pumping capacity of less than or equal to 35 gpm and 899 wells with a pumping capacity of more than 35 gpm.

Effluent Generation

  • Refer to Table 3.5-8.
  • There is one wastewater treatment facility, the Douglas Wastewater Treatment Facility, located at Douglas.
  • About 18,000 people are served by this facility.
  • Almost 1,400 acre-feet of effluent per year is generated by the facility and discharged to Mexico where it is used for agricultural irrigation.
