Executive Summary:
Chemicals represent a large investment in the effective operation of Flagstaff Water Services treatment plants.  These chemicals are critical to the treatment of water and wastewater in order to comply with water quality regulations and ensure the public's safety.  These chemicals are unavailable in the City of Flagstaff and must be delivered; many are located outside of Arizona.  Bulk chemicals are purchased by each treatment plant on an as-needed basis based on the demand for water, reclaimed water, and the treatment of wastewater.  These chemicals disinfect and remove impurities from all water sources including potable drinking water, reclaimed water, and wastewater.

These purchase amounts exceed administrative authority and require action by the City Council.
Financial Impact:
These competitively bid contracts will reduce the financial impacts to the Water Services Division, consolidating the purchasing needs of these chemicals for Water Production, Wastewater Treatment, and Reclaimed Water Sections.  Funding to purchase chemicals is budgeted within Water Services treatment plant budgets for Lake Mary, Rio de Flag, Wildcat Hill, and Reclaim Water.
Policy Impact:

Has There Been Previous Council Decision on This:
Yes, City Council approved similar bulk chemical purchase contracts from bids in 2006, 2009, and 2015.
Options and Alternatives:
  1. Award the contracts to DPC, Thatcher, Univar, and Hills Brothers as the lowest responsive, responsible bidders for their respective chemicals. Or
  2. Require staff to constantly secure new prices for bulk chemicals for each individual purchase; which may lead to higher purchase and transportation costs and make budgetary decisions more difficult.  Or
  3. Disallow purchase of bulk chemicals which would hinder compliance with State law and Federal water quality regulations.
Chemicals represent a large investment in the effective operation of the Water Services Division's treatment plants.  Water Services use the following chemicals for the respective purposes:
  • Chlorine is used for the disinfection of treated surface water, groundwater, wastewater, and reclaimed water.
  • Sodium hydroxide (caustic soda) is used to raise the pH of treated surface water.
  • Coagulants such as aluminum sulfate and aluminum chlorohydrate are used to remove suspended impurities in raw surface water.
  • Cationic polymers are used to assist in the removal of impurities in water & wastewater.
  • Sulfur dioxide is used in the removal of chlorine from treated wastewater/reclaimed water. 

The recommended award was procured by Purchasing staff through a formal solicitation. An Invitation for Bid (IFB) was posted on PlanetBids from July 16, 2020, to August 19, 2020, and an advertisement was placed in The Arizona Daily Sun on July 26 & August 2 of 2020. Five companies submitted bids: DPC Enterprises, Hill Brothers Chemical, Applied Specialties, Univar Solutions, and Thatcher. After reviewing all the bids, all but Applied Solutions are considered to be the lowest responsive, responsible bidders.
