Water harvesters linked to the stables

[Wells]

Has anyone got a water harvester you use to feed the water troughs or stable automatic drinkers?
We've installed one that currently just links to the toilets but I'd like it to run the horses drinking water as well - is this possible?! Has anyone linked it to the washing machine as well?

We're currently in discussions as to whether we need one or two. If we go for two then I'm intending that the house one will supply toilets and washing machine and the stables one will do animal water.

We've got a 10,000 litre tank so I think it should be big enough to do all jobs but looking back, I think 2 tanks would have been better at managing the house vs stables
