Drinking water comes to you from the 1+ million miles of water pipes that make up America’s water infrastructure system, many of which were put in place in the early-to-mid 1900s. But with a lifespan of 75 to 100 years, this system is starting to show its age.
While quality remains relatively high, the American Society of Civil Engineers (ASCE) estimates that there are over 240,000 water main breaks per year, wasting over two trillion gallons of treated drinking water - or nearly six billion gallons per day. The wasted water could support the everyday water use of 15 million households, and results in $2.6 billion annually in lost revenues.
Despite the occasional news headline, at present the water wastage problem mostly remains invisible. That will likely soon change. Water scarcity is on track to be one of the century’s most important environmental and health issues as nearly half the global population already live in potential water scarce areas, and that population is expected to increase to up to 5.7 billion people in 2050.
At both local and global levels, no one can afford to waste water, which means governments and water utilities companies alike need to arm themselves with tools to prevent such loss. After exploring a recent case of water wastage, we’ll explore why digital field inspection platforms are ideally suited to track leaks throughout drinking water systems.
Mississippi blues: The cost of water leaks
To illustrate this issue, let’s go to Mississippi and look at the case of Jackson’s continuing water leakage woes. A recent report based on citywide November 2021 inspections found that more than 40 percent of treated water never makes it to the customers. Because of the city’s aging pipe system, the water is lost during distribution through main breaks, leaks at meters, or other disruptions causing leakage.
Jackson’s challenge was made worse because its water department pays to treat that water, but can’t recoup its layout: the water never goes through a meter, so customers don’t receive it, and no one is billed for it. This produces a troubling deficit, and one that keeps getting worse: in 2017, the city brought in $61 million in water and sewer revenues but had $65 million in expenses. By 2019, revenues were $49 million, while expenses were $77 million.
Without fixing the city’s aging pipe system, this discrepancy will only get worse. But without the massive budget required for a complete overhaul, the city resorted to what it felt was the only solution: raising water and sewer rates by 20 percent across the board.
