JACKSON, Miss. – The sunshine is back, and the ice has melted. But more than a week after a deep freeze across the South, many communities are still grappling with getting clean water to their residents.

Families stood in lines for hours to get drinking water. They boiled it to make it safe to drink or brush their teeth. They scooped up snow and melted it in their bathtubs. Hospitals collected buckets of water to flush toilets.

“You don’t realize how much you use water until you don’t have it,” said Brian Crawford, chief administrative officer for the Willis-Knighton Health System in the northwestern Louisiana city of Shreveport, where water pressure at one hospital only started returning to normal Wednesday. Tanker trucks had supplied it with water since last week.

For years, experts have warned of the need to upgrade aging and often-neglected waterworks. Now, after icy weather cracked the region’s water mains, froze equipment and left millions without service, it’s clear just how much work needs to be done.

The still-unfolding problems have exposed extensive vulnerabilities. Many water systems have decades-old pipes, now fragile and susceptible to breaking. White flight dropped tax revenue in some cities, and a lack of investment has caused problems to become even costlier to fix. Many systems in the South were not built with such low temperatures in mind. But with climate change projected to bring more extreme weather, problems like those seen last week could return.

A 2018 survey by the U.S. Environmental Protection Agency estimated $473 billion was needed over 20 years to maintain and improve water infrastructure. In a 2020 report, the American Society of Civil Engineers said a water main breaks every two minutes on average in the U.S., and described “chronic, long-term and insufficient investment.” The report warned that the “nation’s public health and the economy will be at risk."

Actually, it's already happening.

The Mississippi capital of Jackson struggled to fix its damaged water grid, with thousands still facing outages. In Memphis, residents in the city of 650,000 were told for nearly a week to boil water for three minutes if they planned to use it for drinking, cooking or brushing their teeth. The boil-water advisory was lifted Thursday. Nearly 25,000 Louisianans still had water outages Thursday, and hundreds of thousands more were under boil advisories.
