2017-2018 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:

from 2005 to 2015)

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

How will rates change?
With recent improvements in the state’s water supply picture, our focus turns to driving progress on vital infrastructure upgrades. Allowing critical water supply assets like Anderson Dam to fail is not an option. The proposed maximum groundwater production charge increase for FY 2017-18 will help drive progress on the Anderson Dam Seismic Retrofit project, which will help ensure public safety and bolster future water supply reliability.

In addition, we are projecting lower water usage than pre-drought averages, which results in lower revenue and puts upward pressure on water rates in the near term. However, over the long term, reduced water use per capita will reduce the need for long term investments in accessing new supplies, which will help reduce rate increases in the future.

The district is proposing South County Zone W-5 rate increases for FY 2017/2018 as follows:

  • Up to 6.4% rate change
  • Current 2016/2017 charges: $393/acre-foot
  • Proposed maximum 2017/18 charges: $418/acre-foot
  • Average household increase: $.86 per month
