Members of
the Peachtree City Water and Sewerage Authority and City
Council met for a few minutes Monday afternoon in a
special session, during which they mostly assured one
another that all were on the same page regarding the
safety of the city's water system.
WASA
officials discussed details concerning the two recent
spills into Lake Peachtree, but also emphasized the
continuous work being done to bring the system up to
where it should be since its purchase from Georgia
Utilities.
Some of the
150-mile sewer system, the size of which is said to have
been underestimated some 20 percent by Georgia Utilities,
dates back 30 years with little or no attention being
paid to it, according to WASA Chairman John Gronner.
New
equipment is being implemented this month that will help
keep an eye on the entire system and spot potential
problems. A television system that will take pictures of
the system is coming online to complement a new vacuum
truck acquired this spring.
Whereas
recent responses to spills have been reactive, Gronner
said, new advances in technology such as this will allow
a more proactive response.
The most
recent spill was caused by a clog due to the accumulation
of roots, along with a manhole that was too shallow,
according to WASA board members and general manager Larry
Turner. The root problem is systemic of what exists
throughout the system, Gronner said, and with most of the
lines 25 feet below the ground, getting to every trouble
spot is not an easy task.
Once the
new TV equipment is in place, the goal is to photograph
the entire sewer system every three years - roughly
one mile per week, Turner said. WASA staffers are working
right now inspecting the lines and gathering data for
regular maintenance in the future, he added.
Mayor Pro
Tempore Annie McMenamin said that measures such as these
will improve the system and ease the concerns of citizens
such as those she has been hearing from in recent weeks.
Saying that
her top concern is the safety of the citizens, McMenamin
noted that a perception exists throughout the community
that because the second spill was so soon after the
first, the problem could have been better addressed the
first time.
When told
that the two spills had two different causes, she replied
that a more proactive WASA approach in explaining what
has happened would possibly help the situation.
Gronner
said that because everyone wants to know immediately
about such incidents and the authority complies with
information, notification about a spill often comes out
before the cause of it is known.
WASA
officials said that the percentage of spills in Peachtree
City is lower than in most places near Atlanta, although
they are working with a "no-tolerance" approach
toward such problems.
Turner said
that no specific data was kept during the time Georgia
Utilities owned the system, but he has learned that
overflows were a regular occurrence back then, as often
as 10-15 times a year.
Some
information from the U.S. Environmental Protection Agency
was distributed and discussed, and Turner pointed out
that Georgia is one of four states with notification
procedures in place for spills, such as when the state's
Environmental Protection Division and Fayette County
Water System was informed of the two recent spills.
Recent EPA
statistics also indicate that 60 percent of river runoff
and 50 percent of lake runoff found in chemical tests can
be attributed to agriculture, Turner said, adding that
such factors as construction sediment, fertilizer and
other materials flowing into the lake due to a hard rain
are the main problems.
It was also
pointed out that homeowners must be educated as to their
responsibilities in keeping the lines clean, because
improperly tying in water that runs off their yards can
cause an imbalance in the sewer system in areas that WASA
staff is unaware of.
"Citizens
expect spills, but not repetition in the same
places," said McMenamin. "We should let folks
know ASAP when proactive things happen."
