Document Description
The proposal project entails the horizontal directional drill (HDD) installation of a 6" and 8" pipelines (4" and 6" interior diameter) under Smitchneck Creek. No water will need to be diverted. No rip rap, culverts will be necessary. The project does not entail open trench excavation; therefore, excavation volume calculations are not included.
The HDD entails equipment mobilization on the west side of the stream in an open disturbed area. A small diamtere pilot hole located ~15 ft under the streambed is first drilled from one end of the alignment to the other. Subsequently the bore is enlarged to accommodate pipeline insertion. The 2 pipes will be placed one above the other and seperated by ~10 inches. A redundancy pipe is necessary to keep effluent moving should the main 8 inch pipe clog at some point.
The HDD operation will avoid the discharge of water, drilling mud and cuttings to the adjacent land during the construction process. The Contractor shall provide equipment and procedures to maximize the recirculation or reuse of drilling mud and minimize waste. All excavated pits used in the drilling operation shall be lined by Contractor with heavy-duty plastic sheeting and sealed joints to prevent the migration of drilling fluids and/or ground water.
