Meanwhile Tom Heap has discovered that an innovation to a product we use every day, an innovation which promised to save water is actually making things worse. Billions of litres are being wasted every week – enough to supply the cities of Edinburgh, Cardiff, Sheffield, Manchester, Liverpool, Bristol and Belfast combined – welcome to the Great Leaky Loo Scandal.
We reveal how this is happening and what can be done. Tom gets a revealing look behind the scenes at a plumbing manufacturer where flushing systems are tested and the science of ‘solids discharge’ is analysed.
When water is being abstracted from rivers and being treated to meet our demands we ask if we need to take the resource more seriously.
