The City of Winooski, Vermont is soliciting sealed bids from qualified suppliers for the annual purchase of Accu-Tab Blue

equipment. The City anticipates purchasing approximately 120 sixty-pound pails annually.

* Product shall be suitable for commercial swimming pool applications and comply with applicable federal and State of
Vermont requirements.
* Any proposed equivalent must include written manufacturer documentation confirming compatibility with the City's
existing Accu-Tab/PowerBase chlorination equipment and confirming that use of the proposed product will not
adversely affect applicable equipment warranty or NSF certification/listing.
* The City reserves the right to reject any proposed equivalent for which compatibility, safety, certification, or warranty
status cannot be satisfactorily demonstrated.
3. Estimated Quantity and Ordering
The estimated annual requirement is approximately 120 pails. For bidding and planning purposes, the City currently
anticipates approximately five (5) separate releases during the operating season, with each release consisting of
approximately one full pallet of twenty-four (24) 60-lb pails (approximately 1,440 lb per pallet). The 24-pail pallet quantity
is an anticipated ordering quantity and shall be confirmed by the successful bidder based on the manufacturer's standard
pallet configuration.

anticipate accepting delivery of the full annual quantity at one time. Bidders shall provide pricing applicable to individual
