Cultural water demand data including population, number of wells and the average well pumpage and non-groundwater use by the municipal, industrial and agricultural sectors are shown in Table 8.3-10. Effluent generation including facility ownership, location, population served and not served, volume treated, disposal method and treatment level is shown in Table 8.3-11. Figure 8.3-12 shows the location of demand centers. More detailed information on cultural water demands is found in Section 8.0.7.
Cultural Water Demands
- Refer to Table 8.3-10 and Figure 8.3-12.
- Population in the AMA increased from 35,641 in 1980 to 90,061 in 2000 and projections suggest an increase to over 200,000 residents by 2030.
- The majority of the water used in the AMA is groundwater.
- In the period of 2001-2005, municipal water demand accounted for 72% of the total average annual water demand.
- Agricultural demand dropped by more than 60% between the early to mid-90s and 2001-2005 and has continued to drop as agricultural land is developed and taken out of production.
- As of 2005 there were 10,651 registered wells with a pumping capacity of less than or equal to 35 gpm and 724 wells with a pumping capacity of more than 35 gpm.
Effluent Generation
- Refer to Table 8.3-11.
- Nine wastewater treatment facilities were identified in the AMA.
- There are a wide range of effluent disposal methods including discharge into a watercourse, permitted recharge projects and golf course irrigation
- More than 6,800 acre-feet of effluent are treated/generated annually in the AMA.
