Home My WebLink AboutPR 17501: SLUDGE PUMP MEMORANDUM CITY OF PORT ARTHUR UTILITY OPERATIONS DEPARTMENT TO: Floyd T. Johnson, City Manager FROM: Kelly Eldridge, Director of Utility Operations y ked_tri DATE: January 16, 2013 RE: Proposed Resolution No. 17501 COMMENTS RECOMMENDATION I recommend the City Council approve Proposed Resolution No. 17501 authorizing the purchase of a Sludge Pump from Hartwell Environmental Corporation, of Tomball, TX, in the total amount of $12,973.75. BACKGROUND This bare -shaft pump will replace one of two existing units in the Port Acres WWTP Centrifuge Building. This type of pump is used to pump thickened sludge into a decanter centrifuge for dewatering before disposal in our landfill. These units are `bolt -in' replacements to the existing pumps. Otherwise, we would have to re -pipe the entire manifold in the building. This unit will also utilize the existing drive unit (motor, electronics and control system). We were able to obtain only one quote (attached) for this pump since Hartwell Environmental Corporation is the authorized distributor in the State of Texas and should be considered a sole source for this equipment. No Port Arthur vendors supply this equipment. BUDGET /FISCAL EFFECT This equipment was budgeted in O &M account no. 410 - 1256- 532.92 -00 at $16,250. STAFFING /EMPLOYEE EFFECT City staff will install & operate this pump. SUMMARY I recommend that the City Council approve Proposed Resolution No. 17501. P. R. No. 17501 01/16/13 RESOLUTION NO.
