Leverage Data to Better Understand and Manage Water Supply, Usage, and Trading

Climate change and population growth are driving many communities to make tough decisions about water use. It is more important than ever that water managers and agricultural water users have access to the best possible data to balance supply and demand. ESA is deeply involved in the challenge to chart a sustainable future for water resources. The Groundwater Accounting Platform is the result of a partnership with Environmental Defense FundOlsson, and ESA.

This platform enables water managers, landowners, and water users to track water budgets and usage in near real-time. The platform includes modules for groundwater modeling and water trading, providing a complete set of tools for local water districts to better manage allocations over time. As open-source software, the Groundwater Accounting Platform provides a springboard for water districts everywhere to launch and customize their own software applications.
