An Urban Drought Reserve Enabled by State Groundwater Recharge Legislation

Abstract

For decades, the city of Albuquerque, NM, relied solely on groundwater for its municipal water supply. However, concerns about long-term sustainability of its local groundwater resources spurred the Albuquerque Bernalillo County Water Utility Authority (the Water Authority) to pursue a groundwater recharge project which could serve as a drought reserve for future municipal use. Aided by new favorable state groundwater recharge legislation and funding, the Water Authority developed the Bear Canyon Recharge Project. The project utilizes portions of the Water Authority’s Colorado River water that is unused in a given year, delivering the water to an unlined arroyo channel where it infiltrates into local aquifers. As the first groundwater recharge project successfully implemented in New Mexico, the Bear Canyon Recharge Project required significant local effort to navigate the institutional and regulatory necessities that arose in implementing an onstream recharge project. The project illustrates that state support can be necessary but not sufficient for local implementation of groundwater recharge and points the way for other water utilities in the state who may be looking to implement groundwater recharge projects.
