Drop 1 Hydro Rake System Replacement Project

The Imperial Irrigation District has issued a forecast for the Drop 1 Hydro Rake System Replacement Project located in Holtville, California. The project involves replacing an end-of-life DT8300 debris removal hydro rake system with a modern, automated DT9300 system to improve operational reliability, enhance worker safety, and support continued hydroelectric generation. This upgrade is necessary due to the degraded state of the existing equipment and the limited availability of replacement parts. The project is categorized under NAICS code 238210 and was posted on July 15, 2026. The scope of work includes the installation of a new boom assembly, rake head, raking flags, hydraulic manifold systems, reservoirs, motors, pumps, and a hydraulic oil cooler. Technical upgrades feature the replacement of microswitch-based controls with a modern proximity sensor system and the installation of new HMI/PLC controls for automated operation and monitoring. The new system will be integrated with existing rails and transporter/conveyor equipment that will remain in service. From a regulatory standpoint, the project has been certified as categorically exempt from further environmental review under the California Environmental Quality Act (CEQA) under Class 1 and Class 2 exemptions.
