East Highline Reservoir Project

The Imperial Irrigation District is seeking a qualified contractor to design and construct the East Highline Reservoir (EHR) – a 2,100 acre‑foot off‑line storage reservoir and a 1.8‑mile intake canal in Imperial County, California. The scope includes mobilization, traffic control, extensive earthwork, deep‑dynamic‑compaction and stone‑column ground improvement, concrete and steel structures (gate buildings, spillway, inlet/outlet gates, metering bridge), fiber‑reinforced concrete and geomembrane lining, cathodic‑protection systems, mechanical/electrical equipment (generators, PLC, telemetry, flow/level instruments), environmental mitigation (wetland turnout, storm‑water pollution prevention), demolition, de‑watering, and full commissioning. The contractor must provide all labor, materials, permits, safety programs, and comply with Buy‑America, California OSHA, and EPA regulations. • Comprehensive civil‑construction package covering reservoir excavation, embankments, canal lining, and structural gate installations. • Mechanical/electrical scope includes slide‑gates, overshoot gates, generators, PLC‑based control systems, and telemetry. • Environmental and safety requirements mandate storm‑water plans, hazardous‑waste handling, emissions compliance, and mandatory pre‑bid job‑walk.
