Trouble in the Pipes: Aging Sewers Threaten Environment, Public Health
Despite penalties, sewer systems still fouling rivers, streams

America's sewers are showing their age.
Deteriorating pipes, overwhelmed by volumes of water they were
never designed to carry, release billions of gallons of raw sewage
into rivers and streams each year. The spills make people sick,
threaten local drinking water and kill aquatic animals and plants.
Hundreds of municipal sewer authorities have been fined for spills
since 2003, according to a Gannett News Service analysis of EPA
data.
And dozens of local governments have agreed to spend billions
modernizing failing wastewater systems over the next 10 to 20 years.
Many of those projects will be financed by rate increases.
But the improvements can't keep up with problems affecting the
thousands of miles of sewer pipes snaking underground through each
community. Foul-smelling waste gurgles from manholes and gushes down
streams and rivers somewhere in the U.S. almost every day.
In March, between 700,000 and 1.3 million gallons of human feces and
other waste spilled from a damaged pipe into Grand Lagoon at Panama
City Beach, Fla.
In January, about 20 million gallons of sewage flowed into
Pennsylvania's Schuylkill River after a 42-inch pipe ruptured near
Reading, Pa.
That same month, heavy rain, deteriorating pipes and operator error
combined to send about 5 million gallons of sewage into Northern
California's Richardson and San Francisco bays.
"When people flush their toilets, they think the sewage is going to
the treatment plant, and that's where they deserve to have it go,"
said Nancy Stoner, a project director at the Natural Resources
Defense Council, which says the government isn't doing enough to
police sewage overflows.
GNS analyzed enforcement and compliance records compiled by the
Environmental Protection Agency and some state regulators between
January 2003 and February this year. The analysis found:
- At least one-third of the nation's large, publicly owned sewage
treatment systems have been penalized by the EPA or state regulators
for sewage spills or other violations. The penalties included fines
and orders to fix problems or expand treatment capacity.
That doesn't mean other sewer systems are problem-free. Federal and
state environmental officials say they target sewer systems with
ongoing overflows that come to regulators' attention through routine
inspections, complaints or large spills that generate headlines.
- Total fines amounted to $35 million. The fines were assessed
against 494 of the nation's 4,200 municipal facilities that treat at
least 1 million gallons of sewage daily. In addition, some states
have levied penalties that aren't included in the data.
- Cities with the largest fines included San Diego ($6.2 million),
New York ($3 million), Los Angeles ($1.6 million) and Pittsburgh
($1.2 million).
"The word is out," said Mark Pollins, the EPA's director of Water
Enforcement. "Enforcement is alive and well."
EPA officials estimate 850 billion gallons of storm water mixed with
raw sewage pour into U.S. waters every year from systems, some built
in the 19th and early 20th centuries, that are designed to overflow
in wet weather.
An additional 3 billion to 10 billion gallons of raw sewage spill
accidentally every year from systems designed to carry only sewage,
according to the EPA. Those spills are caused by numerous factors,
including improper connections, clogs caused by debris, construction
accidents and cracks in aging pipes.
As many as 5,500 people get sick every year from direct exposure to
pollutants discharged from sewer overflows near beaches, the EPA
estimates.
Sewage also can get into drinking water. In one 1993 case in
Milwaukee, more than 400,000 people got sick and more than 100 died
after the cryptosporidium parasite contaminated drinking water taken
from Lake Michigan. A study published in the New England Journal of
Medicine suggested untreated sewage in the lake could have been the
culprit.
EPA officials say water quality has gotten better in many
communities that have improved their sewer systems.
Elsewhere, regulators and lawsuits filed by citizens have pressured
local governments into agreeing to costly, complex modernization
projects that in some cases will take more than a generation to
complete.
Pittsburgh's Allegheny County Sanitary Authority, for example, has
agreed to eliminate dozens of "outfalls" that discharge sewage mixed
with storm water directly into rivers and streams. The project could
cost about $3 billion over the next 20 years.
"We're not alone," Arletta Scott Williams, executive director at
Pittsburgh's wastewater treatment plant on the Ohio River, told
homeowners attending a town hall meeting last fall. "It is
nationwide. There's nowhere near enough money, and there's no pot
where it's going to come from."
Ratepayers certainly will be asked to help foot much of the bill.
In Louisville, Ky., residential sewer rates jumped 30 percent last
year to help finance an $800 million sewer renovation program that
won't be completed until 2024.
"We don't have any recourse," Louisville resident Roseanne Southard
said as officials prepared to approve the increase. "These agencies
all want more money, and I'm not making any more."
The nation's public wastewater treatment plants and sewage
collection systems need about $350 billion to $500 billion over the
next 20 years for repairs and expansion, according to estimates from
the National Association of Clean Water Agencies. The trade group
based the estimates on figures from the EPA and other federal
agencies.
This year, the federal government has budgeted $687 million for
wastewater improvement, according to the National Association of
Clean Water Agencies.
One modernization project alone, in Indianapolis, could cost $1.2
billion. Residents hope the repairs will end years of smelly and
unsightly problems along Fall Creek.
"I have walked this area on numerous occasions and could see condoms
decorating bushes where the water level had been high (and),
feminine hygiene products along the shores, toilet paper hanging in
bushes," said Richard Van Frank, a local environmental activist and
retired biochemist.
Legislation that would require sewer authorities to notify the
public of overflows and spills is pending in Congress.
One environmental group, American Rivers, uses humor and a "Spill of
the Week" Web blog to encourage support for a nationwide public
notification law.
"We try to be a little snarky about this," said Josh Klein, a
campaign coordinator for American Rivers. "After all, we're talking
about poop. But it is a serious issue."
Overflows cost sewer systems $35 million in fines over five years
Gannett News Service analyzed federal data on fines and other
enforcement actions related to sewage overflows from municipal sewer
systems. The data is from the Environmental Protection Agency and
covers from January 2003 to February 2008.
The analysis found:
- At least one-third of the nation's large, publicly owned sewage
treatment systems have been penalized by the EPA or state regulators
for sewage spills or other violations. The penalties included fines
as well as orders to fix problems or expand treatment capacity.
That doesn't mean other sewer systems are problem-free. Federal and
state environmental officials say they target systems with ongoing
overflows that come to regulators' attention through routine
inspections, complaints or large spills that generate headlines.
- Total fines amounted to $35 million. The fines were assessed
against 494 of the nation's 4,200 municipal facilities that treat at
least 1 million gallons of sewage daily. In addition, some states
have levied penalties that aren't included in the data.
- Cities with the largest fines included San Diego ($6.2 million),
New York City ($3 million), Los Angeles ($1.6 million), and
Pittsburgh ($1.2 million).
- States where sewer systems paid the largest amounts in fines, both
federal and state, were: California ($7.8 million), Tennessee ($3.4
million), New York ($3 million), Kentucky ($2.9 million), Maryland
($2 million), Florida ($1.5 million), Pennsylvania ($1.4 million),
Indiana ($1.4 million), North Carolina ($1.2 million), and Oklahoma
($1.1 million).
- The EPA records show no fines were levied against sewer systems in
Arizona, Hawaii, Kansas, Oregon, Maine, South Dakota, Vermont, West
Virginia or Wyoming.
- The records showed no enforcement action of any kind for sewer
systems in four states -- North Dakota, Nevada, Washington and
Wisconsin. |
