Hi all,
Braddon,
I would go to the local water resources department and see if they had any detailed maps as to aquifiers in the area. They could give you an indication as to how deep you may have to drill.
If there is water under your neighbours, then there is a good chance of having it too, unless there is a fault line between you and a dramatic change of geology.
We are on tank water, and have dams as well, which we use for gardens and toilet. If your tank does run out then you can just buy water in. If you are renting the house out, the cost of purchasing extra water if needed is borne by the tenant.
Bridie,
water divining!!, next we will have to get out the ouija board, form a circle ,hold hands, and ask the spirits(bundy for me) where we should next invest!!!
