California has a knack for writing checks it can’t cash. California has been over drafting their water savings account for years and now over pumping groundwater is over drafting aquifers which lead to subsidence. Land subsidence occurs when large amounts of groundwater have been withdrawn from certain types of rocks, such as fine-grained sediments. The rock compacts because the water is partly responsible for holding the ground up. When the water is withdrawn, the rocks falls in on itself. You may not notice land subsidence since it can occur over large areas instead of a small spot like a sinkhole. Just because we can’t see it that doesn’t mean it’s not there costing states like California, Texas, and Florida hundreds of millions of dollars in damages over the years. According to experts, in California’s Central Valley alone the subsidence and damage to infrastructure is requiring repairs costing billions of dollars.
Up until recently pumping groundwater was unregulated. Farmers and landowners across the valley relied heavily on pumping groundwater during California’s water crisis to keep their businesses and homes operating.
“In 2016, NASA’s GRACE satellite verified that aquifers all over the world are being depleted. Normally, over time, aquifers refill with rainfall, snowmelt and floodwaters, but due to increased use, combined with droughts that dry up surface water, more than half of the U.S.’s aquifers have not been refilling during the past decade.” – Samantha Fox
When land subsides, it compacts, becomes denser, and can’t hold water like it used to. This results in increased surface flooding and permanently reduces aquifer recharge. The inability to recharge the aquifer and boost groundwater supply is a downward spiral of issues when it starts to impact surrounding infrastructure costing billions in repairs.
Luckily, the Sustainable Groundwater Management Act is on the side of stormwater capture and aquifer recharge. Practical solutions begin with drywells. Not only are drywells a small footprint stormwater management solution, they come with an affordable price tag and improve a projects capacity for aquifer recharge.
Whether you’re familiar or unfamiliar with our products, we can provide a free Lunch & Learn that demonstrates the power of our systems and gives insight on how to include them on your next project. MaxWell® has been outperforming other drywells for over 44 years. Learn more about the history of the MaxWell here.
