Tuolumne Meadows Water Treatment Facility Regulatory Upgrade

Yosemite National Park » Tuolumne Meadows Water Treatment Facility Regulatory Upgrade » Document List

This project proposes to add a flocculation process to ensure adequate cryptosporidium removal compliance and meet the increased regulatory requirements. Adding an engineered 4,100 gallon pressure detention tank will allow proper time, flow baffling and particle collision for polymer reaction ensuring proper pathogen removal. The Department of Health services has approved this process addition.
The new tank is 10' long and 8' wide and would be located on the south side of the water treatment building in a currently disturbed area containing underground water piping. The slab or footings for the tank will be 8' x 10' or smaller, dependent upon seismic code requirements. No vegetation or trees will be removed in this process addition. This area is not visible to the public. Consulation meeting with Laura Kirn, park Archeologist, she had no concerns regarding this project. Consultation meeting with Charles Palmer, Acting Chief, Historic Architect and Landscape, he had no concerns regarding this project.
