I would more concern on if you have the water rights to your property, if you own it or if the landlord does if you rent.

I have been reading, that in many places across the US they are putting meters on peoples wells and even going so far as to criminalize the catching and using of rain water. If you can believe that. Sorry no links but if required I can find them. I would just play it on the down low, perhaps they will never be aware of your spring. fB
