Division.
RECOMMENDATION
We recommend the City Council authorize Repairs to an Aeration Basin Screw Pump by PEMSCO, of Beaumont,
TX, ire the maximum estimated amount of $35,494.
BACKGROUND
The Main WWTP Aeration basin LS utilizes three large screw pumps to lift sewage into the unit for treatment.
One c:rf these units is in need of immediate repairs, as the upper bearings have gone out. However, we felt it best
to get: a quote for the lower bearings also, as they are not capable of being inspected until the entire unit is
remo~~ed. PEMSCO has provided a quote for the upper bearing portion only ($26,920.), as well as an additional
quote if the lowE~r bearings and journal have to be replaced ($35,494.). The difference of $8,574 is recommended
for authorization, but aftE:r removal, we will inspect the unit along with PEMSCO and determine if this additional
work. ~s necessary. Due to the age and service conditions of the unit (25 years in raw sewage), we expect it won't
be in good condition. Three local vendors were contacted, but only PEMSCO responded.
BUDGET/FISCAL EFFECT
We would like to use lefil over TWDB funds from our Phase I projects if the TWDB allows.
Accolant No. 42.6-1625-~i32.33-00 Project Nc-. 426020
STAF'FINGIEMPLOYEE; EFFECT
City staff will assist with the reinstallation and start-up of this unit.
SUMMARY
The quote from PEMSCID, of Beaumont meets our requirements and is therefore recommended for approval in
the maximum estimated amount of $35,494.
