RECOMMENDATION ,,
We recommend the City Council authorize the Emergency Purchase of 36" Repair Couplings from HD Supply, of
Beaumont, TX, in the amount of $8,100 for repairs to the Main Outtall Lift Station-Force Main.
BACKGROUND -
A recent 36" force main failure effectively shut down operation of our Main Ouffall Lift Station. Our crews worked
through then night installing compressioh repair clamp(s) like we use daily on water main leaks. However, the top
section of the 36".ductile iron pipe installed during the 1980's was deteriorated too badly to hold up to the
compression, and adjacent sections `split7broke open. Our personnel ..scrambled through the, .weekend,
intermittently pumping, to acquire and install alternate materials in an effort to get the leak reduced or stopped. It
became apparent that we were going to have to replace a section of pipe: We are the ohly area city that keeps
anything; pipe or repair clamps, in this large size in inventory, tiut we needed specialty fittings to effect repairs.
Our normal supplieYs were able to locate these materials across the country. HD Supply contacted the factory
who manufactured two of these large fittings for us at a cost of $8,100including overnight shipping. During the
course of our repairs, we were able to successfully dismantle one mechanical joint bell and reuse it with on-hand
jointing material; so we only used one fitting. The other fitting will remain in our invehtoryforfutiare use. Our crews
worked 24 hours continuously IastTuesdey night to get the LS back-into service before lastweek's rainfall event.
Note that this failure was on our"new'~force main that has been in serviceabout 2b years. The parallel, 'old'. FM ,
-has been in service since-9961-.and is in much worse condition. Also; repairs were made much-more difficult
since there are no valves on this FM and we could not use our only liffstation during repairs. We will add a valve
on this Tine during the upcoming-Main WWTP Rehabilitation Project.
BUDGETIFISCAL EFFECT
Funds are available in our operating budget account 410-1255-532.33-00 (Sewer System Maintenance).
