Archie:
My favorite irrigation story is from when we were rebuilding Atlantic City CC.
The first design comes back and it has like 1,300 heads . . . on 110 acres that already has grass on it.
We are all in a meeting [client(s), superintendent, project manager, my site rep, etc] and I say, "I must not be understanding something here. What do you want this course to look like?"
Project manager [Billy Z]: "We want it to have an eastern Long Island, Shinnecock / Maidstone look."
Me: "But Maidstone doesn't even have fairway irrigation."
BZ: "We want it to look like that, but perfect."
Me: [sighs, tries another tack, turns to superintendent]: "With all those little mister heads around the bunkers, you are going to need to have two full-time guys doing irrigation work."
Superintendent: "I've already got them in the budget."
At that point, I glanced over at the client to see if he was getting up to grab the superintendent by the collar, but he was not. So I gave in.
If they really wanted to spend that much I should have charged more for the design.
I would generally defer to a golf course superintendent as to what he wants, and irrigation is very different from one region to another. But, more than once I've superintendents sold on a system so complicated that they don't ever use it to the best of its ability.
On top of that, several of the best superintendents I know NEVER water the greens except by hand, so just right there is 100+ sprinkler heads they didn't need.
PS to Shel: I've asked those irrigation designers to give me data on a system where they used less water after they put in a new system. The only one which has come back that way is Pasatiempo, and that's because of water restrictions. Usually, when clubs put in a new system, the members want the superintendent to TURN IT ON, and he is obliged to follow their guidance.
