Status Active

Total Project Cost: $650,000

Description Replace the (4) four variable frequency drives (VFDs) on our high service pumps.

Justification The VFD's servicing our high service pumps will have been in operation for approximately 21 years when this project reaches construction. This is a typical life span for VFD's. The VFD's have begun to show signs of deterioration with the loss of communications due to worn electronics components and the new SCADA system was modified to accommodate the out-moded communications protocols utilized by these drives. We anticipate continued and more frequent repair activities as these drives reach the end of their useful life.
