According to Fox 19 Now:

Out of sight and often out of mind – it’s a vast network of pipes, wells, and pump stations stretching from one end of Cincinnati to the
other. 

Even though much of it is hidden beneath our streets and sidewalks, the city’s water infrastructure plays a crucial role in public health, safety and economic well-being. Building, replacing and renewing this infrastructure is an ongoing mission.

FOX 19 Now found out the Greater Cincinnati Water Works has a plan to replace one percent of its distribution system annually to keep up with replacement of the aging infrastructure.

Water Works responds to and repairs more than 1,500 water main breaks per year in Hamilton County.  Cincinnati also has 400 miles of water line and more than 3,200 miles of water mains to maintain in Hamilton County.

And we’re far from alone. According to the American Society of Civil Engineers (ASCE), much of the drinking water infrastructure across the country has reached the end of its useful life. 

ASCE’s “Report Card on America’s Infrastructure” gives the country’s overall water infrastructure a D grade. The report card notes that there are about 240,000 water main breaks every year in the United States.

Finally, for overall perspective:

Cincinnati has about 3,000 miles of sewers, 30,000 storm water inlets, 2 drinking water treatment plants, 7 wastewater treatment plants, more than 109 wastewater lift stations; more than 3200 miles of water mains,  12 ground storage water reservoirs, 13 elevated water storage tanks, 18 pump stations and more than 209 CSO storm water outfalls.
