In large-scale water supply operations involving the use of tankers, the "loader" position at a fill site becomes a pretty important position in terms of running the fill site like a NASCAR pit stop. If you follow our seminars and YouTube channel you know that we are a fan of using LDH to supply some type of manifold from which multiple tankers can be hooked up and loaded....one at a time of course. This set-up seems to work best when one person can be dedicated to the "loader" position and simply open and close valves on the manifold. Of course this requires people and we realize that early in an incident people and appliances might just not be available yet. But as water supply operations continue so should the expansion of the fill site....eventually leading to a fill site crew with each member with designated jobs. The Loader controls the flow of water into the tankers....one tanker at a time.
