Understanding Avondale’s Water Portfolio 2023


 Effluent Credits *4,216 acre-feet (AF) of water banked as Long Term


Storage Credits (LTSC). This value increases each year. The water is pledged towards future economic development in Avondale through our LTSC account and to


re-designate our 100-Year Water Supply in 2025.

Along with our current water supplies the City also has “insurance policies.” These are accounts of water that we do not use; they are for when we experience a shortage on the SRP or CAP system due to operational factors or poor watershed years.

Central Arizona Groundwater Replenishment District (CAGRD): The City of Avondale has enrolled in the CAGRD as a Member Service Area (MSA), but has not relied on the CAGRD to replenish groundwater. As long as the City continues to recharge sufficient renewable supplies (i.e., surface water or effluent water) to offset the amount of groundwater pumped each calendar year, it will not be required to pay replenishment fees to the CAGRD. The City does not yet pay annual membership dues to the CAGRD because current projections do not show a need for CAGRD replenishment. Avondale works hard every year to achieve “safe yield”, which means we recharge an equal amount of renewable water as we pump out of the ground. Achieving “safe yield” (not overdrafting the aquifer) is proper water resource management, and keeps our water rates steady. The cost would be significant if Avondale’s water demand outpaced supplies, which would require CAGRD replenishment.
