Rain water collection tank
As the chateau has a lot of roofs and we're adding a large patio around the barn and hose pipe bans are not uncommon during the summer months, we decided to collect this run off water and install a 10,000 litre tank which will be buried in the ground between the barn and the trees. We can then use this water for the swimming pool, watering the garden, etc. The water will be filtered before entering the tank and we'll need an electric pump to get the water to where it needs to be used. I've added Daniel to give some perspective how huge the tank is!
