WRF-1 Chemical Injection Flash Mixer and Static Mixer Installation

The City of Corona Utilities Department is seeking the WRF-1 Chemical Injection Flash Mixer and Static Mixer Installation project located at 2205 Railroad St., Corona, California. The primary objective is to enhance the efficiency of the chlorine contact tank at WRF No. 1 without expanding its capacity. The scope of work includes relocating the sodium hypochlorite injection point to the 36-inch line upstream of the tank, installing a static mixer within that line to ensure proper mixing, and placing a new flow meter within the buried vault upstream of the static mixer. Additionally, the project requires rebuilding the flash mixer used for chemical injection and mixing to ensure the sustained functionality of the wastewater management infrastructure. This project is classified as a forecast under NAICS code 237990. It has been granted a Notice of Exemption under CEQA Article 19, Class 2, Section 15302.c, as the modifications involve the replacement or reconstruction of existing infrastructure and are not expected to cause environmental impacts. Administrative oversight is managed by Director of Utilities Tom Moody and Assistant Utilities Director Katie Hockett. While the technical specifications for the installation and rebuilding process are defined, the specific contract value, period of performance, and formal solicitation number have not yet been disclosed.
