2017-2018 North 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.

    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 and toward development of future drought-proof purified water supplies. Schedule extensions for the two largest capital projects (Anderson Dam Seismic Retrofit and the Expedited Purified Water Program), mean that the North County maximum proposed groundwater production charge increase is lower than projected last year, however the District must continue investing significant capital dollars into repairing and rehabilitating the infrastructure required to deliver safe, reliable drinking water to Silicon Valley residents and businesses.

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 North County Zone W-2 rate increases for FY 2017/2018 as follows:

  • Up to 9.9% rate change
  • Current 2016/2017 charges: $1,072/acre-foot
  • Proposed maximum 2017/2018 charges: $1,178/acre-foot
  • Average household increase of $3.65 per month
