About this file
This is a technical engineering drawing for a wastewater infrastructure project at Death Valley National Park. The document is a Plan & Profile sheet (Sheet C5.25) for the Cow Creek Wastewater system along Skyline Drive, designed by T. Francis and reviewed by M. Whelehon, with a date of January 17, 2025. The drawing shows the horizontal plan layout and vertical profile of an 8-inch sanitary sewer line installation spanning approximately 430 linear feet from station CS 151+79 to CS 155+50.
The project includes installation of four new sanitary sewer manholes (SSMH-CC-147 through SSMH-CC-150) with specified rim elevations and invert depths, replacement of an existing cleanout, and sanitary sewer service connections to residences with minimum 2% slope requirements. The design incorporates four separate segments of 8-inch SDR 35 PVC pipe with varying grades: 33 linear feet at 4.34%, 138 linear feet at 7.29%, 81 linear feet at 5.15%, and 178 linear feet at 6.42%. The plan also identifies existing utility crossings including three existing water main crossings, proposed water service crossings, underground power and telephone crossings, and sewer service connections at specified stations. Minimum cover depth is 3.00 feet with actual cover varying from 3.12 feet to 3.56 feet. The drawing references additional related sheets (C2.18, C5.26, C6.2, C5.33, and C7.0) for disturbance limits, tree protection, service details, and other construction specifications.
