In certain parts of the UK our population is growing, that is a fact. There are many reasons for this growth, but this is not within the scope of this post or indeed this blog. This population growth is not evenly distributed, but it is confined to the South East and just North of London. This means that there is huge strain on the infrastruction; the road network, the local ammenities, housing stock and of course resources. In the UK we are fairly disrespectful to our water supply, we take it for granted, “we are a wet country and it rains all the time, right?”. Wrong, whilst it often feels like it rains all the time, only certain parts of the UK receive vastly significant rainfall. The South East is actually very dry and with the now dense population, it has been suggest that the region is equivilent to the Sudan, in terms of water per capita.
The last two years the region has received more than the average rainfall and this has to a certain extent covered up the on-going long term problem. Which is over-extraction. The Environment agency has recently suggested that once the rainfall returns to more average levels, the rivers will start to deplete, which obviously causes all sorts of environmental issues.
A few years ago, a national grid of water was considered and that would mean transporting water along canals and rivers from Wales, Scotland and other areas of high rainfall to the population. So far this yet to be realised and the cost of opening up and perhaps cutting new waterways has proven too costly.
