The Jeddo Tunnel (also called the Jeddo Mine Tunnel) is a drainage tunnel at water level in Pennsylvania. It is one of the Coal Region's biggest discharges of mine water. The tunnel is five miles (eight kilometers) long and was constructed between 1891 and 1894, and at the time of its construction, was reputed to be the largest mine drainage tunnel in the world. It consists of major tunnels A and B, and minor tunnels C, D and X.
The Jeddo Tunnel drains four large coal basins over an area of close to 33 square miles (85 km2). It also drained the collieries of G.B. Markle & Company. On average the tunnel drains 40,000 US gallons (150,000 l; 33,000 imp gal) of water each minute. Sometimes the tunnel drains up to 100,000 gallons per minute. The tunnel is about 5 miles (8 kilometers) long and runs between Black Creek and the hills in Butler Valley. It is 7 by 11 feet (2.1 by 3.4 m). The Jeddo Tunnel is located close to the community of Drums. The tunnel drains the nine major minepools in the area via gravity.
The Jeddo Tunnel drains the mines in 13 nearby communities. These communities are Hollywood, Lattimer, Minesville, Drifton, Harleigh, Sandy Run, Ebervale, Humboldt, Cranberry, Harwood, Stockton, and the Eckley Miners' Village.
The level of precipitation in the watershed of the Jeddo Tunnel between 1996 and 1998 was 48.5 inches (1,230 mm) per year. The average level of surface runoff during the same period was 3.46 inches (88 mm). The base runoff was 32.18 inches (817 mm) inches and the evapotranspiration was 12.87 inches (327 mm) inches. The Jeddo Tunnel is the largest carrier of water away from the Jeddo Tunnel watershed. There are several streams on the surface, such as Black Creek, Little Black Creek, Hazle Creek, and Cranberry Creek. Besides minepools, contributors to the flow of the tunnel include precipitation draining through mines, seepage of streams, and water falling through sinkholes and cave-ins.
