This document is a set of site plans and technical drawings for a wastewater treatment facility project at Lake McDonald/Headquarters Area in Glacier National Park. The drawings include multiple sheets detailing the overall site layout, grading plans, piping systems, process basins, and facility infrastructure.

The project encompasses comprehensive wastewater treatment infrastructure including three primary treatment basins (residuals drying basin, emergency overflow basin, and waste holding basin), a decant facility with associated piping and control systems, process treatment buildings, and related site improvements. Key technical elements include 6-inch and 8-inch foundation drains, isolation and auto-zone control valves, a new ART (Advanced Reverse Treatment) building with asphalt ramp access, spray irrigation heads with 4-inch laterals, multiple control point stations throughout the site with specified elevations and coordinates, and interconnected piping networks. The site grading plan indicates limits of crushed stone paving, rip rap, and asphalt paving in defined areas, along with new fencing requirements and drainage infrastructure. Horizontal and vertical control point tables are provided with precise surveyed coordinates and elevations. The decant facility plans show detailed mechanical specifications including hoist equipment, valve systems, concrete foundations, and membrane liner installation. Electrical site plans indicate power service feed locations, equipment pad positions, and utility routing. Construction is limited to 30 feet outside of the ART building, and all existing spray irrigation heads and plugs are to be removed by the contractor.
