Cities' average distance to surface diversion sources

The average distance to surface diversion sources is expressed in kilometers. Today, cities are looking farther beyond their limits for clean water. On average, cities retrieve surface water from an average distance of 57.86 km. Note that if a city gets a small fraction of its water from surface water, there will be calculated values for this metric, but it is not particularly meaningful for a city's water risk or opportunity profile.
