Innovation in Underground Water Storage
December 16, 2025
Colorado communities are testing new ways to store water in aquifers as part of a sustainable water portfolio that makes use of groundwater. Join us on Dec. 16, 2025 from 12-1:30 p.m. to learn about aquifer storage and recovery (ASR) projects and pilots in Colorado, including Greeley’s new Terry Ranch Project, Castle Rock Water’s investigation into ASR to build up its sustainable water supply, and more. We’ll also hear about efforts and upcoming legislation that the Colorado Department of Natural Resources supports as the state seeks primacy from the EPA to create a state-level program to regulate underground injection wells, including ASR wells and projects.

Kevin Donegan, Colorado Division of Water Resources, Hydrogeology Section Chief
Courtney Hemenway, Hemenway Groundwater Engineering, PE, President
Lauren Moore, Castle Rock Water, Water Resources Manager
