The torrential rain showers which are now a more frequent indicator of climate change in Ireland, quickly fill any regular water butt. What we really need are large enclosed rainwater harvesting tanks, preferably buried underground. However, such items are much more costly than the regular water butts which DIY stores are busy selling at the moment.
The water butts serve a useful purpose in the garden nonetheless. Watering cans are quickly filled by dipping them in rather than waiting for the tap fixture to fill a can up. The cats certainly prefer drinking the rain water from a dish rather than the mains water. It is likely than plants in the greenhouse prefer the rainwater too.

Surprisingly easy to install, these water butts come complete with stand. All that is required is a hack saw to cut the down pipe and a pliers to rig up the connection pipe.
