This is a technical drawing and sectional plan for the Amistad Power Plant, prepared for the International Boundary and Water Commission between the United States and Mexico. The drawing depicts the unwatering and station drainage erection bay design with detailed mechanical specifications and layout configurations.

The document shows a cross-sectional view of the drainage and structural systems for the power plant facility, with multiple numbered components highlighted in yellow for identification. Key elements include pipe sleeves, steel platform construction, stem guides, valve configurations, and floor slab specifications. The reference drawing references Sheet 174 for the drain and inlet schedule, and Sheet 161 for general notes and legend. The drawing includes a key plan in the upper right showing the overall facility layout and directional orientation. Two revisions are noted at the bottom: one adding a 12-inch "E" valve on the North Face Drawing, and another correcting a "BF3" Pickup on the same drawing. The document is identified as Sheet 1 of 2 with revision history and was prepared by Harza Engineering Company and Associates, Inc., indicating this is part of a larger contract or project documentation package for infrastructure development.
