Inshriach goes sustainable part V.

Today has felt pretty calm after the tempest of trades that have been here the last few days. Only me and mum and Dean the plumber were on the job today. The cellar looks more and more like a boiler room, two new 300 litre tanks found their way down there and Dean has been stitching it all together. I fed the vacuum pipes into underground electrical conduit to give them some protection from the roots of the tree and any vehicles passing that way, then laid them into their trench. It would have been good to finally fill that in but the piles of earth that came out of the trenches are frozen solid.
