About this file
This is an engineering design drawing for a water main installation project at Death Valley National Park. The document is a plan and profile sheet (Sheet C2.20) for the Cow Creek Water system, specifically depicting the water main route from Old Ghost Road to Road 143. The drawing shows a horizontal plan view with topographic contours and a vertical profile view displaying the water main alignment, service connections, and existing infrastructure crossings.
The project includes installation of an 8-inch water main with six 1-inch water service connections located at stations CW 266+79.74, CW 267+27.81, CW 267+51.69, CW 269+22.84, and CW 269+77.99, along with an 8-inch by 6-inch hydrant tee at station CW 266+89.27. The design accommodates two existing water main crossings at stations CW 267+84.64 and CW 268+83.11 and provides a minimum cover of 2.50 feet with an actual cover of 4.02 feet in the designated area. The drawing specifies protection requirements for existing fire hydrants and trees within the 50-foot and 20-foot disturbance limits. The project was designed by L. Ottey, technically reviewed by M. Whelehon, and was dated January 17, 2025, with the drawing number 318717-C2.20 and PMIS package number 178069.
