Messrs J H & M M Jones
Arable farm
"Our aim was to renovate an old yard and get it up to modern farming standards. One of the ways we did this was by putting up a new building over an existing silage clamp. We really wanted to utilse the water that would fall on the roof, so we went for a Premistore rainwater harvesting system.
Cotterills helped me work out what size tank to use based on my roof area and the amount we need to spray a season. They are from a farming background so I found them easy to talk to and they understood what I was trying to do.
I ended up needing a 54,000L tank and one fill will cover our fields twice a season. With their guidance, installation was pretty straight forward and I've been able to get the system installed in between other jobs around the farm."
