I have mains water for the house but collect water from the barn roof for livestock and polytunnel irrigation. The previous owner put in a large ex oil tank, it holds several thousand litres, but I'd like to expand the capacity a lot by plumbing in black IBC containers.
IBC hold 1000 litres each and cost about £50, so I'm thinking I could tuck 10 behind the barn and just link them together with hose.
Has anybody else done this ? Your thoughts would be appreciated.
