Glacier Point Location Assessment for an Alternative Sewer System
Yosemite National Park » Glacier Point Location Assessment for an Alternative Sewer System » Document List
This project proposes the collection of soil data that will be used to locate a potential sewer disposal system for the Glacier Point sewer facilities. Piezometer holes will be drilled to monitor groundwater levels during the entire open season of the Glacier Point area. The data collected will inform park staff about percolation rates and whether they are sufficient based on current codes and standards.
The two sites that are targeted for investigation are the old Imhoff Tank/disposal field, and the current leach field (near the ranger cabins). The project proposes to make 6 piezometer holes (12 feet deep) and 10 percolation holes (2 to 6 feet deep) within the old Imhoff Tank/disposal field. Holes will be 6 inches in diameter or less.
The project proposes to make 8 additional piezometer holes (12 feet deep) and 8 percolation holes (2 to 6 feet deep) within the current leach field. Holes will be 6 inches in diameter or less.
