I've been thinking about saving water. Partly as conservation, which defra's consultation paper would seem to support, and partly as a 'grey water defence' should the drought order come in that this time they have made clear would include us.
It would cut down on my bills as i am on a meter.
It would also be a good enviromental selling point possibly stickered onto the side of my vans.
I have a large five bedroomed house with a largepitched roof ground floor extension, a detached double garage, and a shed /chalet the size of double garage. My point being that this 'roofAge' for want of a better word could suitably fed into water butts supply a lot of water to my ro rather than the drain.
There might even be some grants avialable or some tax advantages, any DIY site that supported such a scheme could well cop for some defra money.
Just an idea, I'm not hot the mechanics, but I think at some point this will have be pursued .
