Project Scope: Total replacement of the existing water distribution system. New supply piping will be installed between the existing ground-well and water storage tanks. New distribution piping throughout the Mayfield Hydro Project primarily in existing road-beds connect to existing service pipes (i.e. 1-inch to 2-inch service lines that supply each building). While trenches are open for water pipe installation; conduits, communication vaults and electrical hand-holes will be installed to upgrade the infrastructure around the Mayfield Hydro Project. Six (6) fire hydrants will be installed throughout the Mayfield Hydro Project to bring it up to compliance with local fire regulations.
Scope of work will also include the realigning of approximately seven hundred (700) feet of roadway to the West by cutting into the rock slope in order to move the road away from the step downslope where it continues to settle and slough. The goal is to cut into rock surface and slope it back to obtain a solid base for the roadway and competent sloped wall on the inboard side.
Estimate: $1,800,000 – $2,000,000
