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.
