This document is a bid-ready electrical power and lighting design drawing set for the Town of Leesburg, Virginia's Water Pollution Control Facility Solids Processing Improvements - Phase 1 project. The drawings, prepared by Hazen and Sawyer engineering firm under Job Number 31111-098, provide comprehensive electrical infrastructure plans for multiple facility components including the Primary Sludge Pumping Stations (Nos. 1 and 2), Thickened Sludge Pumping Station, Gravity Thickeners (A, B, and C), Scum Pits (1 and 2), and the Solids Electrical Building. The design scope encompasses power distribution, lighting layouts, hazardous area classifications per NFPA-820-2024, grounding systems, motor control centers, switchgear, panelboards, and associated electrical schematic diagrams. Electrical equipment includes multiple pumps (primary sludge, scum, thickened sludge, centrifuge feed, digester heating water, and recirculation pumps), grinders, mixers, screens, thickening equipment, unit heaters, exhaust fans, and emergency systems. The drawings indicate forced ventilation systems at six to twelve air changes per hour to downgrade hazardous area classifications from Class I Division 1 or 2 to unclassified in select areas.

The electrical design provides detailed specifications for equipment ratings, conductor sizes, conduit routing, control systems with variable frequency drives (VFDs), and integration with a programmable logic controller (PLC-38). Ground systems utilize #4/0 bare copper wire installed thirty inches minimum below finished grade with exothermic welding at crossing points and bonding to structural steel and motor frames. The project includes dual switchgear units (SWGR-SEB-1-A and SWGR-SEB-1-B) each rated at 2500 kVA with 480V, 3-phase, 4-wire configuration, motor control centers (MCC-SEB-1 and MCC-SEB-2), and panelboards supplied by separate transformers. Fire alarm and lightning protection systems are specified under separate specifications (28 46 20 and 26 41 00 respectively). All drawings were issued for bid set in May 2026 and prepared under IFB No. 500640-FY27-02, with the design reflecting coordination requirements with mechanical systems, instrumentation, and vendor-supplied control panels throughout the facility.
