Water & Other Effects
I have been the TD for many shows that required water and other effects. Some that seem simple, like a tiered fountain can be much harder than expected, and what seems like a huge undertaking is nothing more than filling a really big box with water. Below are samples of some of the water and other special units created for productions at The University of Memphis.
For the end of show a trapped shaped to match the Sapsea mausoleum popped out of the rake creating an actor entrance. It is operated by pneumatic pistons and controlled off stage using a solenoid valve.
The raining elevator in Eurydice. The elevator doors are rigged to open from back stage using a rope and pulley system. The rain and flood were created with a pool pump. The water returns to a catch basin underneath.
The pool for Metamophoses had a 7000 gallon capacity and was heated and filtered. The steel framed deck of the set overhangs the water, allowing for actors to enter and exit unseen. The orchestra lift was reinforced with shore posts (usually used for concrete forms) to hold up the 65K pounds of water and set.
Poseidon and his henchmen were able to enter unseen and begin their attack to the surprise of the audience.
The heating and filtration system for the pool. The pool was also vacuumed with an auxiliary unit nightly.
For actor safety and comfort the pool was heated to 100°F before each performance. To maintain most of the heat overnight the pool was insulated. Heated Changing rooms were also provided to the cast.
A hand carved fountain for Much Ado About Nothing. To get even streams of cascading water, there are strategically placed pieces of drinking straw in the upper-most tier.
The bottom tier of the fountain, and the top of the wall are both fiberglass covered so as to be actor practical.

This was built for the digging of the well. It is operated by a small scissor-lift mounted on a rotating arm.
The lift was built from an electric screw-drive pulled from an unused lectern.
This shot shows the pneumatically controlled arm that moved the collapsed trap under the deck to make room for the actor.
