Vendor Quotes
The Wastewater Facility has four Raw Sewage Pumps to convey the wastewater
into the plant. During normal flow conditions, only one pump is needed.
However, when there are high flow conditions, the Facility needs up to three
pumps.
Three out of the four pumps have older, obsolete drives. If there is failure to the
drives, there are no longer parts available and replacement is time consuming, as
there is a lead time for the parts, the installation takes time, and then the drive has
to be programmed into the SCADA system.
It is a benefit to the City to purchase new drives proactively. Facility staff reached
out to three companies for quotes for the drive replacements and associated
installation accessories. We recommend the purchase through the low bidder,
Grainer of Manchester, NH for a total cost of $29,357.85.
Grainger, Manchester, NH $29,357.85
Graybar, Manchester, NH $34,748.64
Gate City Electrical, Nashua, NH $33,000.00
