I think your target to reduce leakages is to low. It might be an easily attainable target and every leak stopped is an improvement but a higher target would give me more confidence in your operation. Targeting 20 - 25% I am sure is achievable and would make huge gains in water savings. If this target is hard to reach then you will come up with ingenious ways to achieve it thus saving on the water. You provide a very good drive to save water with your equipment for customers aerating water, flush sacks etc. Ingenious and all helpful so why stay there. I had never heard of these and wonder how I can access some of these items myself. All in all positive and progressive but a little more publicity to what you are doing and what you make available might take the issue further forward and more quickly than you may think.
