I've got a project that includes a splash pad. I have concrete pad details from this company:
http://www.rain-drop.com/
They do not mention grounding.
There are no pumps, and there is no pool. Just a controller that plugs in to a receptacle, and it runs solenoid valves. The valves use city water pressure to spray water, which lands on a concrete pad sloped to a drain.
There is a electric foot switch in the pad (I assume its low voltage - but I don't think voltage matters.)
The question is: Is an equipotential grounding grid required??
I found one thread on the issue:

But it didn't seem to generate any consensus.
So what does everyone think: Is a grounding grid required?
