One of the new water butts, available this year, is the wall mounted 105 litre water butt from Ecosure. It collects water from a drainpipe, and is ideal for small, new build home gardens, terrace backyards etc. When completely full it will hold the equivalent of 10 x standard 10 litre watering cans, which can come in very handy for watering flower beds, planters and hanging baskets in the summer. Available in a range of colours to match different properties. More info here>
