Cast iron bath in a field, horse drinking..a water regs nightmare?

[Phil]

I've been asked to fit a ballvalve to two old baths in a field for horses to drink. At the moment its just got hosepipe buried a few inches in the field jubilee clipped to the tap which is permenantly trickling in.

The stable owner is getting a water meter fitted and wants them to fill up and stop.

There needs to be as little brass on show as possible as pikeys raid the field, not to mention protecting pipes from freezing.

The more I think about it he more I think I should walk away?

Fitted a proper horse trough a couple of months ago, ballvalve was in a raised section way above the spill over level in a sealed metal box to protect it, just dug in 25mm alkathene 750mm deep to it and put stopcock in an outbuilding with drain tap for shut down in winter months.
