2-Eagle Mountain WWTF Oxidation Ditch Upgrades Drawing Set 04-17-2026.pdf

This is a comprehensive drawing set for the Eagle Mountain Wastewater Treatment Facility (WWTF) Oxidation Ditch Upgrades project, prepared by Advanced Engineering and Environmental Services, LLC for Eagle Mountain City, Utah. The project, identified as GMP2 (Guaranteed Maximum Price Phase 2) of the 6.0 MGD MBR Wastewater Expansion, focuses on upgrading the existing oxidation ditch to improve capacity to 2.0 MGD average daily flow. The drawing set includes civil, structural, mechanical, electrical, and instrumentation & control (I&C) plans with an expected construction start date of July 2026 and a nine-month construction duration. Key project components include oxidation ditch improvements, oxidation swing zone upgrades with aeration equipment, transfer pump systems, process piping installations, tertiary treatment facility electrical modifications, solids building control panel updates, and comprehensive site coordination requirements. The project is located at 2515 N Pony Express Boulevard, Eagle Mountain, Utah 84005, southwest of the public works building. All drawings are issued for GMP (not for construction) as of April 2026 and include detailed specifications for equipment, materials, installation procedures, and quality assurance requirements across multiple engineering disciplines.

The drawings establish technical specifications for materials including ductile iron pipe (DI), polyvinyl chloride (PVC), stainless steel fasteners, and reinforced concrete, with detailed requirements for pipe bedding, trench backfill, equipment mounting, and structural support systems. Process improvements include three vertical turbine internal recycle and swing zone transfer pumps (IRSW-P1, P2, P3), modulating flow control valves, isolation valves, air/vacuum release valves, flow meters, and level transmitters. Electrical systems incorporate Variable Frequency Drives (VFDs) for pump speed control, supervisory control panels (OXD-SCP1 and TTF-SCP1) with programmable logic controllers, distributed I/O modules, and network-based SCADA communication. Instrumentation includes analytical transmitters for pH, dissolved oxygen, oxidation reduction potential, and nitrate monitoring, along with radar level sensors and electromagnetic flow meters. The construction documents emphasize contractor responsibility for site coordination, utility locating, existing condition verification, environmental compliance, erosion control, dewatering management, and one-year warranty coverage following final acceptance. Construction notes mandate advance notifications to the engineer and owner, coordination with property owners regarding water service disruptions, and adherence to OSHA standards and MUTCD traffic control requirements.
