As Infrastructure Crumbles, Trillions Of Gallons Of Water Lost

Imagine Manhattan under almost 300 feet of water. Not water from a hurricane or a tsunami, but purified drinking water — 2.1 trillion gallons of it.

That's the amount of water that researchers estimate is lost each year in this country because of aging and leaky pipes, broken water mains and faulty meters.

Fixing that infrastructure won't be cheap, which is something every water consumer is likely to discover.

In Chicago, fresh water is drawn into water intake cribs in Lake Michigan and piped to the enormous Jardine Water Filtration Plant on the lakefront, adjacent to Navy Pier.

Jardine is the largest water filtration plant in the world by volume, pumping about 1 billion gallons of purified drinking water out through hundreds of thousands of miles of pipes to 5 million people in Chicago and 125 surrounding communities.

But not all of that treated, potable water makes it through the system to homes and businesses. In fact, quite a bit of it is lost.

The Chicago-based Center for Neighborhood Technology, a nonprofit focused on sustainability, recently put out a report that estimates "about 6 billion gallons of water per day may be wasted in the U.S.," says Danielle Gallet, the group's water supply program manager.

Where does it go? Much of it just leaks out of aging pipes and water mains that crack and break.

"We do have a crumbling infrastructure issue," Gallet says. "It is old."

Last winter's extremely bitter cold in the Midwest and Northeast was especially tough on the aging water infrastructure in those parts of the country.

But water main breaks are becoming increasingly common in warmer months too. "We replaced 6 feet of main here [of a] 10-inch main," that burst open 5 feet beneath a busy thoroughfare in the Chicago suburb of Skokie, says Perry Gabuzzi, a maintenance worker for that city's water department, one recent warm morning.

"See the golf-ball-sized holes in it?" he asked, pointing to the section of pipe his crew removed.

The rusted pipe broke open just because of old age. Gabuzzi and his colleagues estimated the section to be at least 70 years old.

In Los Angeles in July, a water main estimated to be 93 years old broke wide open, causing severe flooding on the campus of UCLA.

And these kinds of incidents are happening all over the country, as much of the nation's water infrastructure is now a century old.

"The infrastructure and the massive investment that our grandparents, great-grandparents, some of us our great-great-grandparents put in, is coming to the end of its useful life, and the bill has come due on our watch," Gallet says.

A recent study by Gallet's group and the Chicago Metropolitan Agency for Planning found the Chicago area alone is losing 22 billion gallons of treated water per year through leaky pipes.

"We figured that that could fill the residential needs of about 700,000 people in a year," says Tim Loftus, water resource planner for the agency.

"That's a big city," he says. "That's a year's worth of residential water use."

Nationwide, the amount of water that is lost each year is estimated to top 2 trillion gallons, according to the American Water Works Association. That's about 14 to 18 percent (or one-sixth) of the water the nation treats.

And it's not just water that's going down the drain, but billions of dollars in revenue too because utilities can't charge customers for water that is lost before it gets to them.

But fixing the nation's water systems isn't going to be cheap.

"Our estimates are that this is a trillion-dollar program," says David LaFrance, CEO of the American Water Works Association. "About half of that trillion dollars will be to replace existing infrastructure. The other half will be putting into the ground new infrastructure to serve population growth and areas that currently aren't receiving water."

Across the country, many communities are raising water rates — some in the double and triple digits — to begin addressing the problem. California and Maine, as well as several individual communities, are asking voters next week to approve massive bond initiatives to fund water infrastructure improvements.

But some government spending watchdogs are skeptical.

"Anytime somebody tells me that we have to spend more money, I'm going to look at who is telling me that and do they have an interest in it," says Steve Ellis of the Washington-based group Taxpayers for Common Sense.

He says water utilities stand to gain from massive water infrastructure spending, as does the American Society of Civil Engineers, which gives the nation's water infrastructure a barely passing grade of "D."

Ellis says that doesn't mean big spending on water infrastructure isn't needed. Voters just need to make sure there's proper oversight, as well as investments in better technologies and conservation.

The American Water Works Association is meeting in Atlanta this week in its first conference focused on water infrastructure.

LaFrance says the first priority is to get water utilities to audit their systems and install and upgrade meters where needed. Then they can get a better handle on just how much water is being lost because too many, he says, just don't know.

And in the meantime, the old and crumbling pipes keep leaking.

MELISSA BLOCK, HOST:

2.1 trillion gallons - that's an estimate of how much purified drinking water is lost each year across the country because of aging leaky pipes and water mains. Fixing that infrastructure won't be cheap for states, for communities or for residents. NPR's David Schaper tells us more from Chicago.

DAVID SCHAPER, BYLINE: Danielle Gallet is standing on a point jutting out into Lake Michigan, next to Chicago's huge Jardine Water Filtration plant. A billion gallons of Lake Michigan water is purified to drinking water standards here every day and then pumped to close to 5 million people in Chicago and 125 surrounding communities.

DANIELLE GALLET: Hundreds of thousands of miles of pipes to our showers, our dishwashers, our laundry machines and to our pitchers of water.

SCHAPER: Gallet is the water supply program manager for the nonprofit Center for Neighborhood Technology. She says not all of that treated, potable water makes it through the system. In fact, quite a bit of it is lost.

GALLET: We do have a crumbling infrastructure issue. It is old.

SCHAPER: And that can lead to major water main breaks like this one.

GALLET: In suburban Skokie, where on a recent morning, this water utility crew was pumping out water that was gushing from a burst water pipe five feet beneath the busy thoroughfare.

PERRY GABUZZI: We replaced six feet of main here - ten inch main. There's a piece we took off if you want to take a look at it. See how pitted - see the golf ball size holes in it?

SCHAPER: And what's that from?

GABUZZI: That's just from age, right? It's from old age.

SCHAPER: Any idea how long this...

GABUZZI: How old this is?

SCHAPER: Yeah.

GABUZZI: Ange, do you have any idea how old this main is?

UNIDENTIFIED MAN: Seventy years, probably.

SCHAPER: That's Perry Gabuzzi. He and his peers across the country have been busy replacing broken water pipes, many of them 70, 90 and even more than 100 years old. Again, Danielle Gallet.

GALLET: The infrastructure and the massive investment that our grandparents, great-grandparents, some of us our great-great-grandparents, put in is coming to the end of its useful life, and the bill has come due on our watch.

SCHAPER: Gallet's group and the Chicago Metropolitan Agency for Planning recently studied just how much water is lost here. The agency's Tim Loftus says the Chicago area alone is losing 22 billion gallons of water a year.

TIM LOFTUS: We figured that that could fill the residential needs of about 700,000 people in a year. That's a big city. That's a year's worth of residential water use.

SCHAPER: Nationwide, the amount of water that is lost each year is estimated to top 2 trillion gallons. That's about 14 to 18 percent - 1-6th of the water we treat. And it's not just water that's going down the drain, but billions of dollars too because utilities can't charge customers for water that is lost before it gets to them. But fixing the nation's water systems isn't going to be cheap.

DAVID LAFRANCE: Our estimates are that this is a trillion-dollar program.

SCHAPER: That's David LaFrance, CEO of the American Water Works Association. And yes, he said a trillion dollars - with a T.

LAFRANCE: About half of that trillion dollars will be to replace existing infrastructure. The other half will be putting in the ground new infrastructure to serve population growth.

SCHAPER: Across the country, many communities are raising water rates - some in the double and triple digits - to begin addressing the problem. And several, including the entire states of California and Maine, are asking voters next week to approve massive bond initiatives to fund water infrastructure improvements. But some government spending watchdogs are skeptical.

STEVE ELLIS: Anytime somebody tells me that we have to spend more money, I'm going to look at who is telling me that and do they have an interest in it?

SCHAPER: Steve Ellis, of Washington-based Taxpayers for Common Sense, says water utilities stand to gain from massive water infrastructure spending, as does the American Society of Civil Engineers, which coincidently gives the nation's water infrastructure a barely passing grade of D. Ellis says that doesn't mean spending on water infrastructure isn't needed, provided there's enough oversight and conservation. Meanwhile, the water pipes keep leaking.
