Hi, we have just set up our own water supply. We have a spring on our land several hundred meters from the house. We had to cap the spring to protect it from ingress of animal droppings etc and then dig in the pipe to an outbuilding where is goes through a particulate filter, another to address the very slight acidity and then a UV filter. We use two 1100 litre tanks and the water is pumped on demand to the house. We had to have the water tested at a cost of £230. We used Snowdonia Water Services to set the system up and the total outlay has probably been in the region of £5000, including the septic tanks. We do not pay any water rates and the tank will need clearing about once a year. We believe that the system will have repaid its cost in about 6 - 7 years. We have fantastic water - far better than anything you can buy in the supermarket.
If you Google private water solutions it should give you several companies which can assist.
