Sewer Service to the Proposed Coppell Site at SE Corner of Royal Lane and
1-635
There are two possible alternates to serving the proposed site with sewer
service in-lieu of the Septic System currently shown on the preliminary
design for your consideration.
ALTERNATE I:
This will be a gravity sewer system constructed by dry boring method with
steel casing pipe consisting of the following items:
*
1500 lineal feet of 8 inch sewer line
1500 lineal feet of 14 inch steel casing pipe
4, 10 foot by 30 foot bore pits
2-3 manholes
Connection to existing manhole
*
*
*
*
This alternate will take a direct route from the proposed site to an
existing manhole located on the north side of 1-635 just to the east of Park
& Fly lot, which will have enough depth to allow this connection.
Difficulties in accomplishing this task:
* Finding a utility contractor willing to take the risk to run such a
long bore with all liability issues involved
* Access restraints around 1-635 to in the case of need to dig for
problems in boring
* Conflicts with other utilities along the north side of 1-635(Le.
fiber optic, gas, phone .etc.)
* The absorbent cost estimated at about $550,000.
* The time constraints for coordination with all parties to complete
task

ALTERNATE II:
This will be partially gravity to a lift station then partially pressured
system for the rest of the way.
The method of construction will involve open cut as well as dry bore across
the paved lanes of 1-635.
The items required to accomplish task are the following:
*
200 lineal feet of 8 inch sewer line
270 lineal feet of 4 inch steel casing pipe
1100 lineal feet of 3 inch force main
4 , 10 foot by 30 foot bore pits
2 manholes
Connection to existing manhole
*
*
*
*
*
This alternate will take a route from the proposed site towards the corner
of 1-635 and Royal lane for a lift station site and a force main from the
lift station along Royal lane to the north just short of the park & Fly lot.
Difficulties in accomplishing this task:
* Finding a utility contractor willing to take the risk to run such a
long bore with all liability issues involved
* Access restraints around 1-635 to in the case of need to dig for
problems in boring
* Conflicts with other utilities along the north side of 1-635(Le.
fiber optic, gas, phone .etc.)
* The absorbent cost estimated at about $450,000.
* The time constraints for coordination with all parties to complete
task
* Connection is made to a private system on Park & Fly lot (no luck
trying to get them to communicate the possibility of connection
