LIMA UP GROUND RESERVOIR

Project Scope

E.S. Wagner served as the prime contractor for the Lima Upground Reservoir, a major infrastructure project designed to increase water capacity for Allen County and the City of Lima. The massive one- square-mile reservoir was completed within a single construction season. Construction of the embankments demanded precise moisture control and compaction to ensure a watertight system – with daily productions approaching 50,000 CY of excavation. Additional work included the installation of a large- scale blanket drain to prevent subsurface water migration, the relocation of an existing wetland, and the construction of structural concrete influent and effluent control structures including more than 900 feet of ductile iron piping. Final work included placement of approximately 90K tons of slope protection using layered aggregate and riprap systems placed at the top of the 60’ embankments. Despite complex logistics, limited access, and stringent quality requirements, ESW successfully delivered a durable, high-capacity reservoir system.
