More than a million miles of underground pipes carry water to our homes, schools, hospitals, and businesses. These pipes last a long time, but pipes placed during the late 19th century through the middle of the 20th century are nearing—or have already reached—the end of their useful life.
More than a decade ago, the American Water Works Association announced the dawn of the replacement era and the need to rebuild the water and wastewater systems inherited from previous generations. In addition, population growth has increased the demand for water service, placing greater stress on existing pipes and requiring utilities to expand coverage by adding larger pipe networks and repair or refurbish those in use.
The AWWA estimates that the cost will exceed $1.7 trillion through 2050 in order to maintain current levels of water service, with replacement accounting for 54% of the total, and the rest attributed to population growth and migration. Putting it off will only result in poor water service with more disruptions and increasing costs for emergency repairs as pipes fail. The national-level investment facing utilities will roughly double from about $13 billion a year in 2010 to almost $30 billion annually by the 2040s for replacement alone.
