Bang on the money

Last night I was out until midnight chasing the water leak in yesterday's blip. I found a commercial property with a leak of 13 litres per minute, I did some leak detection on the private property as a courtesy and located the leak in the driveway. The only indication of the leak was, water entering the Telecom Pit and the movement on the meter. The issue for the consumer is they would have never known about the leak,until they get their account and I read this meter 6 monthly. Now do the math 13 lpm x 60 = ltr's pet hour x 24 hrs = cubic meters per day @.70c per Cu mtr is a lot of money. The leak was on this Tee and my mark was bang on the money saving the owner a small fortune.
