ITEM SUMMARY:
Liquid Sodium Hypochlorite is one of the various chemicals used at the City’s Water Treatment Plant in
the treatment of the City’s municipal water supply. Approximately 312 tons of Liquid Sodium Hypochlorite
are used annually and is the primary disinfectant used in the treatment process. It reacts with naturally
occurring metals in the City’s shallow wells. It also removes naturally occurring ammonia in the raw water
at all City wells.
On November 20, 2023, the City Council authorized Resolution No. 23-R-0086, a contract award to
Rowell Chemical for procurement of Liquid Sodium Hypochlorite, at a unit price of $0.1729/pound
delivered. A provision of the current Contract allows it to be extended for two additional years, through
mutual agreement between Rowell Chemical 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. Rowell Chemical
has agreed to renew its contract and has also offered a slightly more discounted price of $0.169/pound.
Staff compared this pricing with recently bid contracts by other municipalities. The offered pricing is
slightly lower than recently publicly bid contracts. Due to an estimation error previously, staff is now
estimating approximately 312 tons of Liquid Sodium Hypochlorite will be used in FY2025, which
represents a 13% increase over FY2024 but still well below the average of 400 tons in the years prior.
Staff recommends that a contract be awarded to Rowell Chemical of Hinsdale, Illinois, for Liquid Sodium
Hypochlorite at the unit price of $0.169/pound, for an amount not to exceed $105,456.00 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.
ACTIONS PROPOSED:
Approve Resolution No. 24-R-0072 authorizing the Mayor to execute a contract extension with Rowell
Chemical of Hinsdale, Illinois, for the procurement of Liquid Sodium Hypochlorite for Fiscal Year 2025 in
an amount not to exceed $105,456.00.
COMMITTEE RECOMMENDATION:
The Infrastructure Committee voted 6-0 for approval.
