The city has a new plan to detect water leaks faster, after the revelation that a quarter of its fresh drinking water never makes it to Hamilton homes. Twenty-six per cent of the treated water destined for local taps, or 19.916 megalitres per year, escapes through broken and leaky pipes, says Dave Alberton, Hamilton's manager of water distribution. That's higher than the provincial average of 15 per cent, he said, and it's expensive and bad for the environment.
