Approximately 50 lf of steel bore casing, up to 32 in in diameter, will be installed approximately two ft of vertical clearance from the bottom of the existing culvert. The water pipeline to be installed inside the bore casing is a 22 in diameter coated and lined cement mortar steel pipe. The pipeline will be installed utilizing dry jack and bore method of drilling. A bore pit approximately 40 ft long, 12 ft wide and 12 ft deep will be dug on the east side of the culvert approximately 25 ft from the culvert center line. The receiving pit, approximately 15 ft long, 8 ft wide and 12 ft deep, will be dug on the west side of the culvert approximately 25 ft from the culvert center line.
