ITEM SUMMARY:

Carbon Dioxide is one of the various chemicals used at the City's Water Treatment Plant. Approximately
220 tons of Carbon Dioxide are used annually.  Liquid Carbon Dioxide is used in the treatment process to
stabilize the water chemistry after the softening process is complete. This process, known as
recarbonation, lowers the pH of the softened water to an acceptable level.

On November 20, 2023, the City Council authorized Resolution No. 23-R-0085, a contract award to
MacCARB, Inc. of Elgin, Illinois, for procurement of Carbon Dioxide, at a unit price of $0.15/pound
delivered. A provision of the current Contract allows  it to be extended for two additional years, through
mutual agreement between MacCARB, Inc. and the City,  if pricing were held for each subsequent fiscal
year,  if the City were satisfied with services provided, and if approved by City Council. MacCARB, Inc.
has agreed to hold its pricing for Fiscal Year 2024. Due to an estimation error previously, staff is now
estimating approximately 220 tons of Carbon Dioxide will be used in FY2025, which represents a 22%
increase over FY2024 but still well below the average of 300 tons in years prior.

Staff recommends that a contract be awarded to MacCARB, Inc. of Elgin, Illinois, for Carbon Dioxide, at a
unit price of $0.15/pound, for an amount not to exceed $66,000.00 for Fiscal Year 2025.

Adequate funds will be budgeted in the Water Fund, Water Treatment Plant Operations - Chemicals (06-
34-48-4626) to cover this expenditure in FY2025.


ACTIONS PROPOSED:

Approve Resolution No. 24-R-0071 authorizing the Mayor to execute a contract extension with
MacCARB, Inc. of Elgin, Illinois, for the procurement of Carbon Dioxide at a unit price of $0.15/pound
delivered, for an amount not to exceed $66,000.00 for Fiscal Year 2025.
