I live on the side of a hill and am over 700 feet from the main county water line running along our road. The water pressure at my house is about 40lbs. I would like to increase this pressure to say 60lbs. I also have a barn in which I'd like to run water to, but it sits above the elevation of my house and is about 100' from my house. What can I do to increase the water pressure at my house and my barn?

Do you have a PRV (Pressure Reducing Valve) on the main line?
Could be on the main line in the meter box.
