Attachment 1 - Estimated Pumping Frequency Table.xlsx

This file is an Excel spreadsheet (Attachment 1) detailing estimated pumping frequencies for vault toilets across multiple locations managed by the U.S. Army Corps of Engineers Walla Walla District. The table lists 23 single and double vault toilet locations along the Lower Granite region, including sites like Illia Landing, Little Goose Landing, Asotin Boat Ramp, and Wawawai Landing. The spreadsheet categorizes locations by their estimated pumping needs for 1,000 and 2,000-gallon units, with service frequencies ranging from 1 to 3 times per year in 2025. The locations are grouped under different location codes (LGA, LLA, LMA), suggesting a comprehensive maintenance plan for vault toilet facilities in the Lower Granite area.
