RE: Postal Facility - Bethel Road/Sewer Discharge Location
Per our conversation this date, I am providing you with the status
of this project.
On January 27, staff was asked to review construction plans for
a proposed 6" sanitary sewer, force main from the Postal Facility
on Bethel Rd. and Royal Lane. Staff shared with me their concerns
as to the force main tieing into the existing sewer on Bethel
and Freeport due to the size of that line and the way it had been
routed through the residential area west of Coppell Road. Staff
felt that tieing the force main into this line could cause problems
in our residential sewer mains.
Therefore, staff pursued different locations for the discharge
at the force main. After discussing all possibilities, the Postal
Facility Engineers (MSQ) were asked to consider all possibilities
including tieing on to the Coppell MUD sewer line that ran north
on Royal Lane.
The tie-in to the MUD sewer on Royal Lane is the best option due
to the lenght of the force main being decreased by several hundred
feet. The Postal Site's projected flow is only 5 to 6% of the
total capacity of the MUD sewer line. However, the concern o~
the Postal Facility representatives was that the fee to be annexed
into the MUD was excessively high. Therefore, they have went
before the Board of Directors for the MUD and asked that the fee
be reduced to 50% of the total due to the fact that the District
would only be furnishing sewage collection to the Facility and
the City of Coppell providing the water.
Staff feels that the tie-in to the MUD line would be better because
of the present sewer flow of the 12" sanitary sewer along Grapevine
Creek. Also, the proposed force main eventually would be replaced
and probably at a cost to the city when other development occurs
in the area of Royal Lane & Bethel Road.
If you have any questions regarding this matter, please advise.
