Texas A&M University Physical
ant Department officials aren’t just
mcerned with present construction
r the campus, they’re interested in
hat lies below the surface — the
wage collection system.
The department is wondering how
e collection system will handle in-
eased sewage flow from current
rnipus construction and future
uilding programs.
Two engineering firms have
;en consulted about any problems
rat may result from University con-
ruction and expansion.
The most recent additions to the
■wage lines, the Sterling C. Evans
ibrary expansion and the two mod-
lar north side dormitories — Haas
id McFadden halls — have not
rused any problems. However, the
ussihility of overloading the lines in
re future has not been ruled out.
“We anticipated that there
right be problems from the addition
the dormitories, Haas and McFad
en,’ systems civil engineer Calvin
eigel said. “That’s the reason the
illection system went under
udy.’’
The study shows that the dorms’
aste water runs in to the Houston
treet line, which is not functioning
roperly.
However, Lee Harvey, Haas and
IcFadden head resident, said there
aven’t been any reports of sewage
roblems in the dorm.
Larry Holderly, a Texas A&M gra-
uate student who worked with the
ngineering firm, said if there is any
verloading of the Houston Street
ne, much of the north area of the
ampus will he affected. The two
rodular dorms probably would be
irectly affected because of their
lose location to the manholes, he
aid.
A Physical Plant official, who
sked that he and the engineering
rm not be identified, said depart-
lent officials know the Houston
itreet line does not function proper-
y. Since its construction in 1971, the
ine has not flowed properly due to
ccumulations of grease from Shisa
nd areas of adverse grade, he said.
To lessen the problem, Shisa out-
ow was diverted a few years ago to
nother line. The engineering firm
lid the study as if the Shisa line were
o be routed hack into the Houston
itreet line, as has bedn requested.
The 15-inch Houston Street line
uns from Shisa Dining Hall to the
Jniversity Police Station. It is one of
hree lines that the firm reported
would pose problems if more flow'
were added.
All three lines flow to the Jersey
Street outflow line. The outflow line
carries the sew'age to a waste water
treatment plant off FM 2818, south
of the entrance to Easterwood Air
port.
As a result of the adverse grading
in sections of the Houston Street
line, sewage has to build up consid
erably before it can pass the uphill
inclines, the study showed. Since
there is not much slope to it, the line

ashed that he and the engineer-
ing firm not be identified, said

ton Street line does not function

has a slow velocity, and particles
have a tendency to settle out and
clog the line. In some places, man
holes contained more than a foot of
sludge, the firm said.
The study showed that with fre
quent flushing of the Houston line,
the Shisa line could flow into it with
out any major problems.
Flushing the line requires exces-
The firm recommended rebuild
ing the entire line north of Joe
Routt Boulevard to Hogg Street
(northwest of Sbisa) at a cost of
$177,000. To handle flow from
the additions to G. Rollie White
Coliseum and Kyle Field, the
firm advised that a new $54,000
line be built parallel to the Hous
ton Street line.
sive and costly maintenance and is
also a constant nuisance, Reigel said.
The firm recommended rebuild
ing the entire line north of Joe Routt
Boulevard to Hogg Street (north
west of Shisa) at a cost of $177,000.
To handle flow from the additions to
G. Rollie White Coliseum and Kyle
Field, the firm advised that a new
$54,000 line he built parallel to the
Houston Street line.
The second line of concern is the
Bizzel Street lift station and the line
which serves the east partxff campus .
The lift station regulates the out
flow of sew'age in the sewage reser
voir by pumping it out at timed in
tervals. Lines from east campus con
struction, the married student apart
ments, the Engineering Research
Building, and the under
construction Academic and Agency
Building will be handled by the sta
tion.
The firm said the decision to put
the library expansion flow into an
8-ineh tributary of the 15-inch Biz-
zell Street line was the best alterna
tive. The lift station, however, is not
adequate to handle flow from the
other construction, the report said.
The firm reported that they found
waste water backed up at times in
one of the manholes near the station.
It concluded there is a lack of either
pumping or wet well storage
capacity.
The firm suggested that the
pumps he either adjusted or re
placed. The estimated cost for re
placing the pumps is $35,000.
Added waste to the Veterinary
Medicine Complex line is another
problem area studied by the firm.
The 10-inch line is expected to
serve west campus additions such as
the Medical Science Building and
the addition to the Veterinary Medi
cine Complex. The line crosses
Highway 60 near Agronomy Road
and runs southwest through the
Horticulture Farm.
Flow meter readings showed that
the line was overloaded during the
peak hours of the work week, 10 a.m.
until noon and between 4 and 5 p. m.
During these times, the firm found
waste water accumulated in at least
one of the manholes, forcing the line
to operate under pressure.
The firm offered three recommen
dations, ranging in cost from
$100,000 to $160,000, all with the
basic plan of building larger lines.
Another engineering firm, Bink
ley and Holmes, is doing a prelimin
ary study before designing adjust
ments to the collection system.
Binkley and Holmes has more or
less accepted what the original firm
suggested as far as routing the lines,
Beigel said. They have made some
adjustments that might save some
money.
Since the original firm’s study, the
Physical Plant has decided to keep
the Sbisa waste flowing into the line
it is currently using.
Not only does that allow for esti
mated improvement costs to he lo
wered, it enables an area with a slope
problem (where the Sbisa line con
nects into the Houston Street line) to
be cut out entirely, Reigel said.
By keeping the Sbisa line where it
is, the Houston Street line should be
able to handle waste from all flow
lines without having to be totally re- _
built, Reigel said.
“The new dorms aren’t contribut
ing as much as the Shisa line would
be,” he said. “Without all the grease,
I think the Houston Street line can
be lived with after a few adjustments
are made.’’
Parts of the line will still have to be
torn up and rebuilt, but it can be
done in a section where the line does
not cross with utility lines or steam
tunnels, he said.
Sewage from the modular dormi
tories being built north of Sbisa will
either run into the line Sbisa con
nects with or will enter the Houston
Street line. What effect waste from
the dorms will have won’t be known
until it is decided where the line will
go, Reigel said.
