Apart from a bit of earth moving, there's a polytunnel (6m x 4) to go in and the rain water drainage on that side of the house to be sorted.
It was while working out the latter - Osma Aquacells - and then where to put them ? Ahh - under the polytunnel, but then .... what about water recycling as it might save me putting in a dedicated supply ?
Any one know anything about this type of thing? There's about 50m^2 of roof area. Thanks
