This document is a design and engineering drawing for the San Juan Lateral Turnout Building, part of the Navajo-Gallup Water Supply Project in New Mexico, prepared by the Bureau of Reclamation under the U.S. Department of the Interior. The drawing provides comprehensive technical specifications for flow control valve installations at seven turnout locations: Sanostee, Newcomb, NasChitti, BBN, Coyote Canyon, Rock Springs, and Window Rock.

The flow control valve specifications table details the pipe sizes (ranging from 6 to 12 inches), maximum operating pressures (148 to 237 psi), and maximum operating flows (1.22 to 11.51 cubic feet per second) for each location. General notes specify that all nuts, bolts, and gaskets must be suitable for cold water service; all flanges shall be AWWA Class F unless otherwise noted; all elbows shall be long radius; and hydrostatic test pressure for turnout building steel pipe must be 1.5 times the maximum operating pressure. The document includes references to related drawings for sectionalized valve installation, crownpoint turnout, typical turnout configurations, site plans, thrust blocks, and cathodic protection details. The drawing also provides coordinate locations for each lateral turnout using the NM83-WF coordinate system, with crownpoint identified as the current distribution entry point. Additional specifications address welding requirements, fitting transitions, and control valve flange support specifications to ensure proper installation and operational safety.
