This project for the Western Irrigation District consisted of a rehabilitation of an existing canal drop structure, a replacement of another canal drop structure and two new cast-in-place concrete canal drop structures. As the general contractor, CWP was responsible for the care of water, excavation, impervious clay backfill and the cast-in-place concrete works for each structure. This project required detailed planning to manage the care of water at each unique site and complete the concrete placement in the varying winter temperatures.
