Water and Wastewater Tariff

The Central Arizona Groundwater Replenishment District (CAGRD) is a division of the Central Arizona Project that helps water users in Maricopa, Pima and Pinal counties meet their water supply needs. As a Member Service Area of the CAGRD, the San Tan district pays the CAGRD an annual invoice and assesses a CAGRD adjuster fee to customers to defray this expense. This fee shows up as a regular, recurring line item in customers' monthly water bills. The fee assessed to customers is approved by the ACC through a proposal filed each October.

The fee is based on actual water use within the San Tan system along with the CAGRD's current rates and adjusts annually. Depending on where you live within the San Tan service territory, this adjustment may show up as a slight increase or decrease in the CAGRD line item on your water bill.

The CAGRD can be complicated to understand, but plays a critical role in assuring a guaranteed water supply for water users in Maricopa, Pima, and Pinal counties. For more information about how the CAGRD works, please visit the Central Arizona Project website.
