Byrd appeared in the
Autumn-Summer edition of
“Research and Farming”
which is produced at N. C.
State University. It should
be of interest to landowners
to our circulation area.)
Promising results have
been obtained at the
Tidewater Research Station
near Plymouth on two new
systems for handling home
sewage.
Dr. Bobby L. Carlile, a
soil scientists from N. C.
State University, says the
new systems may help
thousands of home owners
who are having problems
with conventional septic
tanks. After a year of
testing, Dr. Carlile reports
encouraging results from
his “septic renovation
levee” and his “low
pressure, shallow pipe
system.”
“Both of these systems
appear to have possibilities
for soil with shallow
bedrock, high water table or
low permeability,” he said.
A third system being
tested, known as the “Case
system,” has no place in a
high water table area but
may have a place in areas
with slowly permeable soils,
he added.
Dr. Carlile’s work is being
supported by the N. C.
Agricultural Experiment
Station and the N. C.
Agricultural Extension
Service. His field tests were
located at the Tidewater
Research Station because of
high water table and the
widespread problems with
septic tanks in the area.
Also working on the project
is Dr. Keith Cassel, an
NCSU soil physicist.
Over 80 per cent of the
land in one nearby county is
estimated to be unsuitable
for conventional home
septic systems. Another
survey reveals that septic
tank failures are the major
environmental health
problem in 85 of North
Carolina’s 100 counties.
“Our research shows it is
possible to build a septic
field in areas where the soil
is unsuitable for a
conventional home disposal
system,” the NCSU soil
scientist explained.
The septic renovation
levee is simply a mound of
sand and other soil
materials laced with pipe
through which sewage
effluent is pumped.
Treatment takes place
within the mound instead of
below ground, as is the case
with a conventional system.
Carlile’s experimental
mound is about 15 feet wide,
50 feet long and about four
feet high. A smaller mound
might be used where a
shallow layer of natural soil
is available to help with the
treatment.
The low pressure, shallow
pipe system is designed
especially for areas with
shallow soil. This system
features a network of small
perforated pipe buried 12 to
14 inches instead of the
usual 36 inches.
Dr. Carlile estimates that
both systems will be more
expensive to install and they
each require an electric
pump to operate.
However, he feels they
are a satisfacotry
alternative in vast areas of
the state where the soil is
unsuitable for conventional
“on-site” sewage
treatment.
County sanitarians and
health officials are being
kept up-to-date on the
progress on his research.
