Another simple but important message. When setting up a dump tank operation to flow in excess of 1000 gpm folks need to plan to build out the arrangement to accommodate several tankers dumping at the same time. While effective water transfer operations are probably the more critical item to "keep an eye on," the person in-charge of the dump site needs to also ensure that dumping operations are not restricted to just one tanker at a time. We grabbed this photo from our seminar in Riverton, Connecticut two weekends ago. This four-dump tank operation is supplying a 1600 gpm simulated fireground flow and these three tankers are dumping their water simultaneously. Once the flow exceeded 1300 gpm, just about every time you looked at the operation at least two tankers were dumping their water.
