PROJECT TITLE: Cary/Apex Water Treatment Plant –

Finished Water Pump Station Pump Motor Upgrades

RESPONSIBLE DEPARTMENT: Public Works/Utilities

PROJECT FUNDING: $275,000

FIRST YEAR ESTIMATED OPERATING COSTS: None

PROJECT DESCRIPTION:
This project provides for the replacement of the four original five million gallon/day finished water pump motors currently in service at the Cary/ Apex Water Treatment Plant. The FY 2009 appropriation of $275,000 fully supports this project with no additional funding requests anticipated. PROJECT JUSTIFICATION: The four finished water pump motors originally installed in 1993 at the Cary/Apex Water Treatment Plant currently remain in service. The pumps affiliated with these motors were upgraded in 2002 during the last plant expansion project. The motors, however, were maintained as originally installed. Two of these motors serve pumps for the central pressure zone and two serve the pumps for the western pressure zone. All four motors have experienced significant wear since 1993 and have extensive maintenance histories. All four motors have also been electrically rewound a minimum of three times since their installation in 1993. Replacement of the four original motors allows staff to maintain the reliability of the water system while meeting existing service levels for finished water pumping capacity.
