Devin,
I hate to be the messenger... Couple of things to keep in mind. In WA state as of 2009, if you don't have an existing, producing well, then you won't be able to do it legally. It seems the State lost a
class action suit brought by existing water rights holders that too many well permits were being issued. The Courts agreed and a moratorium was placed on new
wells or even using existing wells that could not document usage before June of 2009. I learned all this disturbing info while looking to buy property on the Eastside recently.
The 5000 gallon a day exemption for homes has been closed for now. There are water banks still available in some counties, but you have to buy into them and get a permit. Very bad news for WA. I ultimately walked away from my
plans to locate back to the state based on this development. Hope you have a better situation and can access water.
