In England we always talk about the weather, too wet, too dry, too hot or too cold...
When it is wet, harvest the water for those dry and hot days. A water butt (or two) will help you store this precious water. They can be found in garden centres, sometimes your local council have special offers on (contact them direct)
A mailorder company might be able to drop one off to your doorstep. They come in all different shapes and sizes I found this space Saving Mini Butt for £25.00.
Even if space is an issue in your garden, the slimline Space Sava Mini Butt means that you can now enjoy the benefits of a water butt. Pre-drilled inlets and tap.
