COULD HARRIS COUNTY SAVE UP SOME FLOODWATER FOR WHEN IT’S REALLY NEEDED? Flooding along S. Braeswood Dr., Meyerland, Houston, 77096Finding a way to stockpile floodwater during years of plenty, commissioner Jack Cagle tells Mihir Zaveri this week, might not only help to make more water available for use during Houston’s drought years. It might also be a way to check the Houston region’s tendency for subsidence (that slow, permanent sinking that can happen when groundwater is pulled out of Houston’s soft clay layers too quickly). Or maybe, Zaveri adds, it could be used to help keep seawater from being sucked into aquifers as fresh water gets sucked out the other side — as long as doing so didn’t accidentally contaminate those same aquifers with junk from the surface. Who knows? Nobody, yet — but the county commissioners have given the $160,000 okay to a study team to shed light on whether it would be possible, feasible, or advisible for Harris County to pump floodwater underground for storage during major storms.
