First a hose pipe ban and now canal issues

There is much talk in the industry regarding payback rates, carbon footprints and reliability issues with rainwater harvesting systems. Yet the real issue is the security of the national water supply. We have been far too relaxed over the last century, mainly thanks to the Victorian engineers, driven on by the industrial revolution. Also our perception that the UK climate is wet and therefore water is not a resource, it merely comes out of the tap anytime we turn it on. With an ever-increasing population, possible climate change, evidence is pointing towards more pressure on the most basic of resources.

In recent weeks we saw the start of the first water restrictions in the UK for four years and it was actually very surprising to see it not in the South East, but the North West. Whilst this is more of a pain than a real issue, it points to a potentially greater problem. A single dry season has been enough to stress the supply. Just this week we have seen further evidence of the environmental impact of an over-stressed water supply. As reported by the BBC there are closures of canal ways due to the lack of water, see here The Leeds-Liverpool canal is one of the major parts of the network. Not only does this imply the environmental concerns, but also the impact on tourism and the economic situation.

Also this week, people in the midlands are being asked to conserve water, to avoid a mandatory ban. See here, also from the BBC.

So when the issue of rainwater harvesting is being considered is simply not enough to consider it as a stand-alone solution for a single dwelling, project or even a larger site. Does it really matter that it might not payback in less than three years? Well certainly costs are important and nobody is suggesting otherwise, but maintaining supplies through the use of rainwater harvesting and other water conservation measures.
