body
Summary
If approved, this action will authorize the City Manager to enter into a five-year contract with CalChem Enterprises of Modesto, CA for the purchase of aluminum chlorohydrate to be used in water treatment. Aluminum chlorohydrate aids in the coagulation process for the treatment of potable water. The agreement is for the purchase and delivery of aluminum chlorohydrate for an estimated quantity of 90,000 gallons per year and an annual cost of $194,400.
DISCUSSION
Background
Chemicals aid in the water treatment process. The Treatment Plant incorporates a coagulation process to remove particles found in the raw water pumped from the Delta. The coagulation process is aided by the use of aluminum chlorohydrate, which binds the particles and causes them to settle. Different procedures are then used to filter out the bound particles and chemicals before delivering safe, clean drinking water to Stockton residents.
In 2012, when the Delta Water Treatment Plant began operation, the City solicited bids for aluminum chlorohydrate. Subsequently, the City awarded a 2-year contract with three, one-year extensions to CalChem Enterprises of Modesto, CA. All three extensions were executed, and the final extension expired on June 30, 2017.
Present Situation
On April 15, 2017, the Municipal Utilities Department posted an invitation to bid in the Stockton Record (PUR 17-005) for the purchase of aluminum chlorohydrate for the Delta Water Treatment Plant.
In addition, notifications were sent via e-mail to eight chemical vendors.
On May 11, 2017, the City Clerk opened, examined and publicly declared the sealed bids for the purchase of aluminum chlorohydrate (PUR 17-005).
The bid results were as follows:
