The scope of work shall be finalized upon the selection of the firm(s). The respondent’s submission
shall have accurately described your understanding of the objectives and scope of the requested
products and services and provided an outline of your process to implement the requirements of the
Scope of Work and Services. It is anticipated that the scope of work will include, at a minimum, the
following:
The City is seeking a term contract for the supply of various water treatment chemicals used in the
Water Production Plants. The chemicals are ordered as needed throughout the contract term.
All associated costs for materials and delivery to the City of Denton shall be included. Only the
proposed price will be paid and nothing else. That includes but is not limited to delivery costs, freight,
demurrage, environmental or impact fees, etc.
The delivery of bulk liquid chemicals must be delivered FOB Denton, to and unloaded in the City of
Denton's chemical tanks by the supplier. Deliveries of all chemicals are to be made between the hours
of 7:00 a.m.-3:00 p.m., Monday through Friday at any of the following locations:
Lake Lewisville Water Treatment Plant Lake Ray Roberts Water Treatment Plant
1701B Spencer Road 9401 Lake Ray Roberts Road
Denton, Texas 76205 Aubrey, Texas 76227
City of Denton Water Reclamation Plant
1100 S. Mayhill Road
Denton, Texas 76208
The tanker will be sealed with a security tag, the tag serial number and tanker number will be faxed
to the utility after the truck is loaded and is ready for delivery. The manifest will contain all of the
same information along with the serial numbers, and tanker numbers. The Operators will notify the
supervisors of any discrepancies before proceeding with the off-loading process. Discrepancies will
result in delay of chemicals being off-loaded until the discrepancies are satisfactorily resolved.
Ultimately, discrepancies could result in the loads being refused. In case of emergencies, special
arrangements will be made in advance of delivery.
All drivers, while unloading chemicals, will wear at least the minimum of protective clothing
specified by ANSI/AWWA and OSHA/MSDS standards. Any spillage caused by supplier or supplier
equipment while unloading shall be cleaned by the operator/supplier at their expense. Supplier shall
bill the City only for amount delivered excluding spillage.
In the event the awarded successful supplier is unable to deliver the chemical product as proposed,
the supplier authorizes the City of Denton to purchase the product on the open market. For each time
the supplier is unable to deliver, the supplier further agrees to reimburse the City of Denton for any
amount over and above the IFB purchase price, provided; however, the awarded supplier shall not be
liable for more than a normal delivery.
