big city small town with Bob Rivard

Gregg Eckhardt, fondly titled the 'Nerd King' of South Texas water history, comes with an enviable track record. In a career spanning over three decades, he has dedicated himself to studying the unique Edwards Aquifer, contributing to his expert status in water management. Currently an environmental scientist with the renowned San Antonio Water System, his expertise extends beyond the science - he's a dedicated historian pushing to preserve the fascinating history of the city's intricate water systems. Gregg's passion lies in sharing this captivating knowledge through lectures and talks, which are highly sought after within academic circles and sustainability forums.

Protecting the Edwards Aquifer is not just about preserving our water supply, it's about safeguarding our future and ensuring that our children and grandchildren have access to this incredible resource. - Gregg Eckhardt

In this episode of big city small town with Bob Rivard, you will be able to:

• Dive deep into efficient water conservation and management practices, showcased by San Antonio.

• Explore the Edwards Aquifer's pivotal role as San Antonio's primary water source.

• See how SAWS is redefining the game with innovative secondary water sources for the sprawling metro area.

• Gain insights into the transformative impact of the Vista Ridge project on San Antonio’s water supply framework.

• Uncover strategies to fortify San Antonio’s water system for averting potential water crises in the future.

SAWS' Efforts to Diversify Water Sources To meet the burgeoning water demands, SAWS has brilliantly diversified its water sources. They have tapped into other aquifers, implemented recycle water systems, and launched projects like the Vista Ridge to bolster San Antonio's water supply. By shifting the risk of groundwater availability on contractors, SAWS ensures that if a source becomes unavailable, they are not required to pay for it. This innovative water resource management approach illustrates their commitment to securing the city's water future.

The resources mentioned in this episode are:
