BACKGROUND INFORMATION:
The Surface Water Treatment Facility (SWTF) requires various chemicals throughout the treatment process to produce potable water. Currently, the water treatment facility is using Sodium Hydroxide and Citric Acid to perform periodic chemical washes on the filtration system. Additionally, to generate disinfectant for drinking water, the SWTF relies on National Sanitation Foundation (NSF) grade salt supply. Finally, the SWTF utilizes Soda Ash for pH adjustment and corrosion control in the distribution system. In addition to the chemicals purchased for treatment at the SWTF, Lodi’s municipal wells are disinfected using an NSF grade sodium hypochlorite solution. The City’s wastewater plant occasionally uses sodium hydroxide for effluent pH control and sodium hypochlorite to clean the UV equipment and filters.
Local suppliers were asked to provide quotes for each of these chemicals, and staff has identified the lowest cost vendor for each chemical and respective not-to-exceed contract amounts if all extensions are executed. The breakdown is as follows:
Salt and Soda Ash Supply- Thatcher Company of Salt Lake City, UT ($260,000)
Citric Acid, Sodium Hypochlorite, and Sodium Hydroxide- Pacific Star Chemical, LLC, of Sherwood, OR ($360,000)
Our current contract terms for supply of these chemicals expire on June 30, 2026. Since all allowable contract extensions are exhausted, staff has solicited bids for a new contract for the supply of these water treatment chemicals that will commence July 1, 2026, for a period of three years, with two, one (1) year options to extend. A summary reflecting the quotes received for each vendor is attached to each of the respective draft contracts attached as Attachment 1 and Attachment 2.
Staff recommends authorizing City Manager to execute Professional Services Agreements with the suppliers listed above for SWTF and Well Chemical Supply, for a not-to-exceed amount of $620,000 over the potential contract term if all extensions are executed.

Funding for chemical purchases is included in the Water and Wastewater Operations budgets each fiscal year. This purchase will not impact the General Fund.
