RESOURCE: Storage Tanks

[Steve]

My current 2750l tank is a heating oil tank, bunded ( double layer ). It's been used for rainwater storage for years with no damage. Water is fed down to animal troughs by gravity and up to a sprinkler system in the polytunnel by electric pump with pressure vessel. I drained the electric pump last January when I moved in, but it's a simple job to put it into an insulated box and lag the pipework. Some of the distribution pipework is buried deep enough to be OK, but the overhead sprinklers would be damaged if I didn't drain them.

I will install the IBC containers in a cube shape, linked with lagged pipes, and surround the whole lot with straw bales and bale wrap. I have a lot of old carpet to use too. If this doesn't work I'll have to bury them and rely on pumps.
