REJECTED.
Bid Opening
Sealed bids must be marked with the bidder's name and the designation "SERSG Bid FY27 Water
& Sewer Treatment Chemicals" and identify the item numbers for all items on which you are
bidding. Bids must be received no later than 10:00AM by the clock in the Sharon Town Clerks Office
on Thursday, April 30, 2026. Bids will be opened and read aloud in Sharon Town Hall's 2nd floor
conference room. All interested parties may attend.

SERSG Bid - FY27 Water and Sewer Treatment Chemicals," and is received at the Sharon Town Hall

Award Criteria
The Awarding Authority will be the Board of Selectmen, Town Administrator/Manager, Procurement
Officer or Mayor of each of the SERSG municipalities participating in this procurement. Prices quoted for
an item must be the same for all municipalities except for items which are regionally zoned. A series of
contracts will be awarded to the lowest responsible and responsive bidders for each Item for each
participating municipality. This contract will be one identical to the terms contained at the end of this Bid
Package. This procurement is governed by the provisions of M.G.L. Chapter 30B.
Determination of Lowest Bid Price
Each Item will be awarded separately. The total bid price shall be determined by multiplying the
estimated total quantity for all municipalities for each item by the unit price of the bidder to reach a total
bid price. Each bidder's total bid price is then compared with the other bidders' total prices for that item.
The bidder with the lowest total price will be declared the low bidder for that item. Contract prices remain
firm and fixed for the Contract Term. Unless otherwise noted, all bid prices must include delivery to the
destinations specified which delivery must be made during normal business hours (7:00am - 3:30pm)
unless otherwise specified by the municipality.
Rejection of Bids
Bids which fail to meet the requirements of the Invitation for bids or which are incomplete, conditional or
obscure or which contain additions not called for, erasures, alterations or irregularities of any kind, or in
which errors occur, or which in the sole discretion of the Procurement Officer contain abnormally high or
abnormally low prices for any item shall be declared non-responsive; provided however, the SERSG
Board, if it deems it to be in the public interest, may waive any or all informalities as to form.
Informalities as to substance, however, shall not be waived. Alternate bids will not be considered.
Minimum quantities for deliveries and delivery points are specified. If there is no minimum specified in
6

SERSG Water & Sewer Treatment Chemical IFB FY27
this IFB, none pertains. Bids which specify minimum deliveries different than those published will be
declared non-responsive.
Method Used to Award Contract When There is a Tie
Should there be two or more low bids for the Contract to be awarded which are identical and where the
bidders are determined to both be responsible, the following procedure shall be used to award the
Contract:
a. The Contract will be awarded to that bidder with its office located within the SERSG region
(that region containing all the SERSG municipalities participating in this IFB).
b. If there is no bidder with its office located within the SERSG region or if there are two or more
bidders with offices located within the SERSG region, the award of the Contract shall be
determined by a toss of a coin. Such a toss shall be done in the presence of the respective
bidders.
c. If there are more than two bidders with identical bids, the coin-toss method shall be used by
selecting the first two bidders in alphabetical order and eliminating with a coin toss. This process
shall be continued until such time as there remains one bidder.
Failure to Sign Contract
Failure or refusal of the successful bidder to sign and deliver the required contract and the required
Certificate of Insurance for each municipality within ten days after notice of contract award will result in
rejection of the bid. The Contract will then be awarded to the next lowest bidder or the bid re-advertised,
as decided by the SERSG Board.
HEALTH AND SAFETY
The successful contractor shall fully comply with Chapter 306 of the Acts of 2004. This act is relative to
the health and safety on public construction projects and work.
FUEL COST ADJUSTMENT
Adjustments due to changes in cost of diesel fuel will be calculated as follows. The adjustment is to be
based on the increase or decrease of diesel fuel cost, as measured by the U.S. Department of Energy,
Energy Information Administration baseline cost of diesel fuel determined on the date of the bid. The
increase or decrease, as determined above, will be applied to the volume of fuel used, which will be
determined based on fuel consumption agreed on by each municipality.
Adjustments will be made monthly, based on the cost of diesel for the month used. It shall be the
contractor's responsibility to provide each municipality with full documentation prior to fuel adjustments
being accepted.
