NASA Drains 66-Million-Gallon Reservoir to Upgrade Critical Water System
Why this matters: new research or scientific developments with potential real-world impact.
A powerful but mostly unseen water system at work during rocket engine tests at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, underwent an upgrade in May. Crews brought the High Pressure Industrial Water Facility’s 66-million-gallon reservoir to its lowest level since construction in the 1960s by pumping out about 40 million gallons of water over three days. This brought the reservoir, measuring 800 feet in diameter and about 25 feet deep, down to the level needed to replace a 3,000 gallon per minute pump that supplies water for fire suppression to the test complexes. before after The High Pressure Industrial Water Facility’s 66-million-gallon reservoir is shown at NASA’s Stennis Space Center on May 7 as work gets underway to remove about 40 million gallons of water to complete upgrades.NASA/Danny Nowlin The reservoir is shown at NASA’s Stennis Space Center on May 11 at its lowest level since construction in the 1960s.
