Additional Relief Wells and Collector System Upgrade

Project is at Mohawk Dam, located in Jefferson Township, Coshocton County, Ohio northwest of the Village of Nellie. - Installation of 10 new relief wells with individualized housing, conveyance piping (~500 feet total), and outfall structures. The proposed wells will consist of 12-inch diameter stainless steel wire-wrapped screens with filter pack with depths ranging from 102 to 120 feet into glacial outwash (granular soils). Pilot holes were previously completed for screen and filter design. - Installation of new seepage collection system components including 7 manholes (60 to 84-inch precast concrete), ~1,000 feet of piping (24 to 48-inch HDPE), connections, and 3 outfall structures (36 to 48-inch headwalls). - Modification to, and demolition of, select portions of the existing seepage collection system including manholes, piping, and connections. - Earthwork and stone slope protection construction related to the aforementioned demolition, modification, and installation work. Excavated soils will be reused as fill/backfill with excess or unsatisfactory soils disposed in an onsite disposal area.
