It is funny, well not really, that water in the end can be the biggest problem.A well and deliveries by lorry.
The well will be lost when we sell the old house. At new house I had the tank put on the highest part of the land so at least its good on gravity now, pumping is a nuisance as surprisingly expensive.
So then it will be lorries only. They are 10000 L and I specified a tank of 12000 L so that we don't have to have run out completely to accept a new load, a water meter makes monitoring it easier than having to keep opening it and guessing.
Town water might be possible via a convoluted method which I think I might only go on about if it proves viable but we are above the level of any town reservoirs. It might prove better or even cheaper to get another borehole provided it's not too deep - we used to get water coming out of the side of a hill after heavy rain but we haven't had sustained rain like that for 10 years.
Our underground tank that captures all the rain that falls on the roofs is a godsend for watering the polytunnel and the veg. We are lucky in that for some reason we have springs all over our land, they water the orchard and the flower beds without us ever having to worry about them.
Pain in the rear though, as we had a concrete slab laid for me to put a shed on. It was only sometime after that we noticed that there must be a spring underneath it as the concrete isn't very happy and there is a puddle of water in the middle of it. So anything that matters has to sit on pallets.
Just trying to think what 10k litres looks like. Our pool is 45 cubic metres, so that looks like being just under a quarter of the contents of it. So 12k is a big tank.
So mate, I really feel for you over this.
