About this file

Written by GovTribe AI · Aug 27, 2025

These documents are electrical engineering drawings for the Conshohocken Authority's Wastewater Treatment Plant (WWTP) Low Voltage Switchgear Rehabilitation and Motor Control Center (MCC) Replacements project. The project involves comprehensive electrical system upgrades across multiple buildings including the Control Building, Grit Building, Sludge Dewatering Building, Blower Building, Digester Building, and Primary Settling Tanks. The drawings, prepared by Keystone Engineering Group and dated November 13, 2024, are issued for bidding and include detailed single-line diagrams, power plans, site plans, electrical details, control diagrams, and temporary electrical configurations for various facility electrical systems.

The project encompasses replacing and rehabilitating low voltage electrical infrastructure, with multiple motor control centers (MCCs) and switchgear being upgraded across different plant buildings. The drawings provide technical specifications for electrical equipment including transformers, breakers, panels, and power distribution systems, with a focus on maintaining continuous operational capability during the renovation. The electrical system upgrades appear to be funded by the Conshohocken Authority and designed to improve the reliability, efficiency, and safety of the wastewater treatment plant's electrical systems. Temporary electrical line diagrams suggest a phased implementation approach to minimize disruption to plant operations during the rehabilitation process.
