I've been pondering on high-volume water storage for watering the veggie
plot for some time. I'm thinking about several thousand litres,
collected over the winter from run-off (which handily all ends up in a
single pipe to which I have easy access).

My problem however, is what to store the water in. I can find people
selling large water containers or IBCs (a metre-cube plastic container
in a steel mesh) fairly cheaply on that interweb thing, but the delivery
costs are more that the price of the container.

Anyone have other ideas for bulk water storage? (Or possible sources for
containers that might be reachable from the Taunton area, I guess, so I
can take my trailer and pick them up myself.)
