2021-22 South County Groundwater Production Charge-Setting Process


Our District Act provides that groundwater charges may be levied to further the protection and augmentation of the water supplies as well as produce groundwater for beneficial use; may be collected from all those within a zone who own or operate water producing wells whether currently active or not; and that groundwater production charge revenue may be used to pay for and incur debt for the following:

Water supplies

  • Operate and maintain local reservoirs to capture water and fill recharge ponds to replenish the groundwater basin
  • Purchase imported water and develop local water supplies to replenish the groundwater basin

Water quality

  • Monitor and protect groundwater from pollutants and saltwater intrusion
  • Ensure proper construction and destruction of wells to help prevent contaminants from infiltrating the groundwater basin


  • Plan, construct and retrofit infrastructure such as dams, pipelines, recharge ponds and pump stations to help sustain the groundwater table
  • Operate and maintain pipelines, recharge ponds and pumping plants to help sustain the groundwater table

Last year, Valley Water completed a scientific study of its groundwater benefit zones. Based on a comprehensive evaluation of geological studies, local groundwater, and the services Valley Water provides, the South County was partitioned into three zones. The partitioning ensures that ratepayers are grouped in a way that reflects the most recent and relevant data regarding the services and benefits received by well users. More information can be found online at

How will rates change?

Valley Water staff is proposing the following rates for the modified and new groundwater benefit zones in Fiscal Year 2021-2022:

  • 4.6 percent rate increase for groundwater in Zone W-5, an average household increase of $0.74 per month
  • 10.3 percent rate increase for groundwater in Zone W-7, an average household increase of $1.70 per month
  • 4.4 percent rate increase for groundwater in Zone W-8, an average household increase of $0.50 per month

Agricultural water rates shown in the 2021-22 PAWS report reflects the direction provided by Valley Water's Board of Directors to set the Agricultural water rate at 25 percent of the lowest South County Zone W-8 Municipal and Industrial rate.
