25% is actually a lot lower than it used to be, and not a patch on what is simply discharged down the average Thames Water supplier's drain/on their garden (On average usage was 150 litres per person per day! when I left in 2009). Worldwide there are already big problems with water, especially around the river Jordan in the middle east. Basically we seem to like to live where it's dry, and then wonder where all the water's gone.
With respect to the Thames Water Desalination plant. It's not a big kettle. The plant is a reverse osmosis plant using membranes. It uses energy to do it's job, but far less than boiling it. The daft thing is that it would have made more sense to join up the inflow pipe on the desal plant with the outflow from Beckton STW. THe water being discharged from Becton is significantly cleaner than the river (I've done the lab analysis on both). They wouldn't do that because people don't like the idea of drinking water that's come from a sewage works though, so they extract from the river just downstream from the STW instead.
