About this file
This is a technical drawing document for wastewater infrastructure details as part of the Death Valley National Park Water and Wastewater System Rehabilitation project. The drawing sheet (C7.2, dated 1.17.2025) illustrates five primary wastewater utility details: RV sewer service cleanout/hook-up, RV site utility services, PVC pipe with concrete encasement, aerator mooring mast, and dump station infrastructure.
Key specifications include: 4-inch ductile iron hinged dump station lids with foot pedals and locking caps (OPW 269-0085 or approved equal); 4-inch SDR 26 PVC sanitary sewer service lines with 2% minimum slope; 2-foot by 2-foot concrete collars reinforced with welded wire mesh at 12-inch minimum thickness with 1.5% minimum slope toward center; 3-foot minimum burial depth; 6-inch concrete collars for non-traffic areas; full concrete encasement for PVC pipes with 6-inch spacing on all sides; aerator mooring equipment including 3-inch diameter standard galvanized steel pipe filled with sand, 6-inch concrete cap, and 3/8-inch galvanized ring bolts; and dump station basin configuration of 5-foot by 5-foot with basin drain sloped toward drain at 1.5% minimum. Sign post details include 2-inch by 48-inch galvanized steel square sign post tubing mounted with 6-inch by 6-inch galvanized steel surface mount anchors and 3/8-inch diameter by 6-inch galvanized steel bent anchor bolts (quantity four per sign). The project involves relocating existing signage to new posts throughout the facility.
