WAUSAU, Wis (WSAU) The Wausau Water Works has hired an underground leak-detection company. The city is losing about 480-million gallons of water a year -- about one-quarter of everything the water works pumps.
The Wausau Daily Herald reports that 130-million gallons has been accounted for through water main breaks. The rest is a mystery.
Some of the underground pipes in Wausau date back more than 120 years. It's possible that there's a leak in a remote part of the water system that hasn't been detected. Westrum Leak Detection will spend the next few weeks checking water valves and doing underground inspections. The work will cost $9,500. The value of the lost water on residents' bills would be close to $800,000. Wausau will not raise rates in 2013 to cover those losses.
