If you are interested or already have a rain barrel (Water Butt) attached to one of your down spout / gutter drainpipes, here is what you should do.
Preferably before you install the system, build a good platform to hold your first barrel securely at a good height. Even if you only intend to have a one barrel system, this is still highly recommended to ensure you wont need much alterations later on if you decide to expand the system!
In the below image you will find your typical household rainwater harvester: should you want to expand, you may get away with placing one more final barrel flat on the ground next to the existing one connected with an overflow pipe.

The below image is of a good system where the first barrel was placed high enough to allow the expansion to accommodate another 3 – 4 barrels! So in the case of your typical 220 liter system, you can now potentially increase to a 1100 liter system running off of One Downspout / drainpipe!

Think ahead and be proactive! This summer has been quite dry for us here in Southern England and this year my one barrel emptied quite fast compared with last year and it took a while before the rains came to replenish the lost water, Remember as well to clear debris from the diverter and pipes to ensure you get the full potential out of your equipment.

Register on Streetbank and Freecycle as people give stuff away for free there, a water butt can easily cost £30 new online or at a garden centre, just be sure that if it is not a purpose built water butt / barrel, it needs to be a container that is food grade.
