IBC Water Tanks

An IBC (intermediate bulk container) holds around 1,000 litres in a sturdy steel cage, which makes it a favourite with allotment holders and anyone with a big roof to harvest.

You’ll find the tanks here along with the bits that make them garden-friendly: tap adapters for the outlet valve, lid filters and covers that keep sunlight out to stop algae. Only use a tank that’s been cleaned of whatever it held before. For keeping the water fresh, see our water butt cleaning guide.
