Collecting rain water on our plots makes obvious sense. Some plants prefer rain water – blueberries for example. Having water on a plot is a time and effort saver. With conservation in mind, we ought to avoid using mains water if we can.

A system to capture rain water from a shed or greenhouse is the best way to passively fill an IBC or water butt. However, this may not always be possible or practical and if so, an arrangement like this can work well.

In this case pallet wood was used to create a rectangular frame sitting atop of the IBC and a sheet of polythene with a hole cut in it added to collect the rain. There’s enough polythene to drape into the IBC and the central weight keeps it in place in high winds (for months a brick served the same purpose). This arrangement has the disadvantage that water does not flow into the IBC until it rises above the lip of the container’s mouth.

This example has all of the hallmarks of my usual careful approach to fine woodworking, my high standards of engineering and my impeccable cleanliness, but in my defence it has worked well over five years or so – in that time the IBC has never been empty.

You are welcome to come by and see it in place on Plot 81.

However, Gavin on Plot 7a has raised the bar with his new version of this solution which addresses the shortcomings of the above. Gavin is happy for you to come see the construction details.

Gavin intends to add guttering and a downpipes to capture additional rain off his shed.

Update:

This video includes the suggestion that the whole top be cut off the IBC to achieve catch the rainwater and offers some larger scale options including using a pump.

This video offers ideas for using solar power to pump water from an IBC around an allotment.

If you have another ideas please let us have the details.
