This is a design and engineering document set for sewer system improvements at Davidson River Campground for the US Forest Service in Transylvania, North Carolina, dated January 2025. The project includes comprehensive infrastructure upgrades across two divisions with detailed construction drawings, specifications, and technical details.

The project encompasses new 8-inch gravity sewer mains, 2-inch and 7-inch force mains, and two submersible lift stations with capacities of 180 GPM at 34.3 PSI TDH and 20 GPM at 32 FT TDH respectively. Division 1 covers approximately 2,028 linear feet of gravity sewer and associated infrastructure including new sycamore flats lift station with grading and erosion control. Division 2 extends approximately 1,461 linear feet of gravity sewer and includes a new ranger station lift station with similar site work. The project includes wet wells with valve vaults, service connections, cleanouts, standard sanitary sewer details, lift station foundation details, and erosion/sedimentation control measures. Construction details specify trench specifications for pipe installation, temporary and permanent seeding, land grading, gravel construction entrance/exit, sediment fencing, grass-lined channels, silt sock/wattle for check dams, bore and encasement procedures, keying pipes on slopes, bituminous pavement resurfacing, and standard manhole and service line connections. The document includes signature blocks for district ranger, facilities program manager, public services staff officer, southern region wastewater program manager, southern region engineer, and forest supervisor, with digital signatures dated July-August 2025.
