In many ways, installing a surge tank is simple. If you get it right, all will be well. As is the case with so many watershape systems, however, getting it wrong can lead to serious problems.
Let’s start with some terminology. Surge tanks are receptacles used to accommodate the surge of displaced water in systems that can be generally defined as water-in-transit or gravity-feed systems. This class of watershapes encompasses vanishing-edge details, perimeter overflow designs, slot-overflow systems and gutter installations and is also frequently used in the design of commercial waterfeatures.
In WaterShapes’ November/December 2002 edition, my friend Skip Phillips wrote an important article about designing water-in-transit systems in general and in particular on the many considerations involved in building troughs that adequately handle the flow over vanishing edges – what he calls “attached” surge capacity.
To complement that discussion here, I’ll be discussing in more detail what Skip calls “detached” surge capacity and the remote tanks that are [more]
