After reviewing the more than 50 tanker shuttle drills that we have posted on this site it is pretty clear that those folks who can load tankers using LDH are the same folks that perform quite well at delivering the higher flow rates at the dump site. Effective use of LDH requires the use of LDH appliances. At our 2013 water supply drill in Jarrettsville, Maryland - all of the fill sites used LDH to load tankers. In the photos shown here, we see the Jarrettsville water supply unit take draft from a remote pond and supply water out to a parking lot area where tankers are then loaded using 5-inch LDH. An LDH manifold and jumbo wye were used in combination to support the loading process while also providing a large drain to expedite disconnect operations at the direct fills.
