In Texas, drinking water is a resource that state lawmakers and agencies spend billions to protect, but data show many water systems are still in poor condition. When it comes to water loss, Texas loses a lot – more than a lake's worth, according to the most recent state data available from the Texas Water Development Board. The data is from 2013, but authorities with the board say the data is an accurate snapshot of current water loss across the state. Many public water suppliers are required to submit water audits to the state board, which helps state authorities gauge the conditions of systems across the state. For instance, the city of Houston serves more than two million customers and the city lost about 22 billion gallons in 2013 because of leaks and breaks. That's enough water to serve the city of Arlington, which sits between Dallas and Fort Worth and has a population of about 380,000 residents.
