RP-1 Primary Clarifiers Rehabilitation Project (EN24032)

The Inland Empire Utilities Agency is undertaking the RP-1 Primary Clarifiers Rehabilitation Project (EN24032) at the Regional Water Recycling Plant No. 1 located in Ontario, California. The project focuses on the rehabilitation of ten rectangular primary clarifiers through comprehensive upgrades to sludge and scum collection systems, internal concrete surfaces, covers, fall protection, and scum pumping systems. Specific technical work includes concrete repair, the installation of chain and flights, and the replacement of pumps and the scum well. The process involves receiving new equipment at the facility, removing existing components, and installing new equipment within the same general locations. This project is classified as a forecast under NAICS code 237990. It is designated as a Categorical Exemption Class 2 under the California Environmental Quality Act (CEQA) because the work involves replacing existing utility systems with no expansion of capacity and no change to the facility's overall function. No new buildings are anticipated as part of this scope. The primary point of contact for the project is Pietro Cambiaso, Manager of Compliance and Sustainability.
