Project
Fernan Sewage Lift Station Electrical Repair
General Information

1.0 Scope of Work

The electrical infrastructure powering the two Unimount electric motors (see Pump Label 1 photo for specifications) that drive the lift station pumps presents several dangerous safety hazards to the service technicians who perform routine maintenance and monitoring. The hazards identified are as follows:
Corroded Disconnect and Breaker Components: The damp environment within the vault has corroded the connections and wires in the breaker box and disconnect switch. This presents several unsafe conditions and adds unnecessary wearing to the electrical motors that operate the pumps.
Exposed Power Cables on Floor: The unsecured power cables that come into the vault from the floor present a tripping hazard and are exposed to damage from foot traffic. To protect the cables and technicians, the point of penetration must be secured and the cables protected in a conduit rated for a damp environment. Damaged light Fixture: The existing light fixture uses an A19 lightbulb that, due to the cramped conditions of the vault, presents a risk of being struck by a technician’s head while performing service on the lift station system. As a light source is necessary in the space to insure the safety of technicians, a low-profile light fixture is needed To compound these hazards, the underground vault that they are contained in is cramped with machinery, minimal access to natural light, and often has standing water on the floor, increasing the chances of accidental electrocution. To mitigate these hazards, the exposed cable will need to be replaced and contained within waterproof conduit, the damaged light fixture will need to be replaced with a low-profile light fixture, and the corroded disconnect and circuit breaker box will need to be replaced with new equipment appropriate for the damp environment.

2.0 Background
