Aging water systems leak trillions of gallons of drinking water
In the Detroit enclave of Highland Park, where the population halved in the past 20 years, an estimated 70% of the water is lost from pipes up to 120 years old. Several Chicago suburbs likely are losing more than 40% of water. And some Georgia systems are losing more than 80% of their treated drinking water, said Sunil Sinha, a water researcher at Virginia Tech.
