Atch_2_As-Built_Drawings_GAC_Water_Plant_at_MEVE.pdf

This document is a set of as-built drawings for a water treatment plant at Mesa Verde National Park in Montezuma County, Colorado. The drawings depict the design and construction details of the facility's mechanical, structural, process, and electrical systems.

The project encompasses a comprehensive water treatment system serving the park with multiple interconnected components. Key infrastructure includes process piping for influent and effluent lines, backwash supply systems, and GAC (granular activated carbon) contactors with dual units. The system incorporates house water lines, chlorine feed lines, and GAC waste disposal piping. Mechanical elements include a booster pump, service water pumps, bactwash supply pumps, solenoid panels, and turbiditimeter connections. The contractor package features vessel design specifications including unit dimensions, valve operation modes, nozzle schedules, and diffuser details. Structural provisions include an 8-foot by 11-foot support skid with longitudinal and transverse beams, welded connections, and floor penetrations. Electrical systems involve control panels, signal wiring schedules with specific conductor types and conduit sizes, pressure transducers, and various automated valves and meters. The drawings specify demolition requirements for existing infrastructure, including removal of old piping, pads, and reinforcement. Construction documents are dated 2/26/10 and were designed by RF-SGN, Inc., with technical review by BDS-SGN, Inc., and prepared by Prime Contractor (Alley Bleak, Preferred Contracting & Consulting).
