Authorize the City Manager to Execute Purchase and Implementation of a Complete Overhaul of Two Primary Clarifiers at the President Street Wastewater Treatment Facility with Cornerstone H2O for a total cost of $1,598,000.
 
Primary clarifiers play a critical role as the first stage in the wastewater treatment process. These tanks are designed to remove heavy solids and other materials from influent wastewater, significantly reducing the burden on downstream treatment processes. Their effective operation is essential to maintaining the efficiency of the treatment system and ensuring compliance with environmental discharge regulations. Each clarifier is equipped with a variety of mechanical components, including rakes, chains, wear strips, sprockets, bushings, and gearboxes. Over time, these components deteriorate due to continuous operation in a highly corrosive environment.  
 
The proposed overhaul will address the remaining two primary clarifiers at the President Street facility. The project includes the replacement of all major mechanical components, installation of a new sprocket monitoring system, upgrades to gearboxes, chains, wear shoes, and associated hardware. In addition, the overhaul will include repairs to known structural deficiencies within the tanks, which will be completed by a separate vendor. Brentwood is the sole manufacturer of the replacement and repair components designed to fit the existing clarifier system without requiring modifications to the tanks. However, the authorized territorial representative is Cornerstone H2O. Sourcing components from another vendor would result in increased costs and project delays due to the need for structural modifications. 
 
It is important to note that a purchase was made in August 2025 for similar components. At that time, the department intended to sequentially phase the remaining two clarifier overhauls. However, the vendor has offered discounted pricing if the remaining two tank components are purchased now. Delaying the purchase would result in an immediate 4% price increase, in addition to the potential for further cost escalations. To avoid an estimated $80,000 to $100,000 increase in equipment costs, it was determined that accelerating the purchase is in the best interest of the City.
