To make its magnificent water curtain, Cascade relies on the actuation of 16 solenoid valves. These valves, lined up at the top of the structure, operate at 3 psi. To meet these requirements, Cascade has a large reservoir of 25 gallons and a submersible pump at the bottom of its structure. The pump can supply 1800 gallons per hour at 1/4 horsepower, so to correct the mismatch in flow rates, Cascade has an overflow pipe above the main line of nozzles. This overflow pipe and the water from the curtain flow into a trough, which empties into the reservoir, and starts the whole process over again.
To support and house every part of Cascade’s systems, the team designed and laser cut a modular structure out of 3/16” hardboard. This material and manufacturing process proved cost effective, simple, and easy to adapt on the fly. By making the tall supporting pillars out of 11” interlocking cubes, Cascade is able to be disassembled and reassembled at the desired location without the hassle of transporting a 7’ installation.
