Create a containment, line the interior, and coat the exterior. A 10-person crew from Blastco, a TF Warren Company out of the Houston area, was up to the task. For a 1-million-gallon (3,785.4 m³) elevated water tank in Austin, Texas, which was built in the '80s, the steel surface was in good shape, but it was time for maintenance. Feature 84 JANUARY 2018 COATINGSPROMAG.COM A BY STEPHANIE MARIE CHIZIK PHOTOS COURTESY BCTS Four-Point Play on Texas Tank A ustin, Texas is currently working under water "conservation" restrictions. at means no water can be wasted, bars can only operate patio misters between 4 p.m. and 12 a.m., and restaurants shouldn't serve water unless diners specifically ask for it. As the permanent home to the South by Southwest Music Festival, the Longhorns, and a little under 1 million residents, Austin has a strong need for potable water. It's a hot commod- ity. So whatever holds the water — in this case, the Four Points elevated tank — is crucial. e million-gallon (3,785.4 m³) tank was built in the '80s, according to Blastco's Project Manager, Craig Winter. A lthough the steel was in good shape, it was time for maintenance. Blastco, a TF Warren company, needed to line the interior and coat the exterior. It was smooth sailing to start, but the 10-person crew was oblivious that soon it would have to deal with a seven-week delay along the way. Winter has been on Austin duty for Blastco since 2010. With him at the helm, the crew was sure to be victorious. Time Out on the Field e crew started on the tank 's interior at the end of April. ey worked 12-hour shifts to prep the steel, blasting with ARS Advanced Recycling equipment and AMASTEEL from Ervin Industries. "We use steel grit, so we never have any problem getting the steel clean or the profile," Winter explained. e ARS equipment was kept on the ground in a white shipping container. With a 95-foot-tall (29.0 m) pedestal and a 55-foot-tall (16.8 m) bowl, that meant some mighty long hoses were needed! e crew ran four 150-foot (45.7 m) hoses for blasting from the ground, up through an access way in the pedestal and into the bowl. ey also had two guys vacuuming up the spent abrasive to recycle it. e crew worked to blast the approximately 20,000 square feet (1,858.1 m²) to achieve a NACE No. 2/Society for Protective Coatings (SSPC) Surface Preparation (SP) 10: Near-W hite Blast Cleaning. ey sprayed out the entire interior of the tank in about 9 days, and they kept most of the blast with the use of a dehumidifier from Dehumidification Technologies before URETHANE STEEL TANK ACRYLIC
