Raw Sewage Pump Updated Drive Purchase
To approve the purchase of three new Raw Sewage Pump drives and associated
installation accessories in the amount of $33,000 from Granite City Electric
Supply Company, of Nashua, NH. Funding will be through: Department: 169
Wastewater; Fund: Wastewater; Account Category: 81 Machinery and
Equipment.
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.
This purchase was originally approved at the December 14, 2017 Board of Public
Works meeting. When we tried to purchase this product through the low bid
vendor, we were declined as the part they originally quoted was the wrong part
and is now obsolete. We are now seeking approval for the next low vendor for the
correctly quoted equipment. We recommend the purchase through the second low
bidder, Granite City Electric Supply Company, of Nashua, NH for a purchase
price of $33,000.
Grainger, Manchester, NH (obsolete) $29,357.85
Graybar, Manchester, NH $34,748.64
Granite City Electric Supply Company, Nashua, NH | $33,000.00
