Guide to Lift Station Components

Wet Well

The wet well is essentially a storage basin where the wastewater accumulates. This is the first stop in the lift station where sewage and wastewater are collected before being pumped out. The wet well is designed to hold a specific amount of wastewater, preventing overflow and allowing the system to handle varying levels of incoming flow.

Maintenance Tip: Regular septic tank pumping and wet well cleaning are essential to prevent solids from accumulating and causing blockages or pump failures.

Pumps

The pumps are the heart of the lift station. Depending on the system's design, there may be one or more pumps, which are responsible for moving the wastewater out of the wet well and into the sewer system or treatment facility. These pumps are typically submersible and are designed to handle the tough, corrosive environment found in lift stations.

Types of Pumps:

• Centrifugal Pumps: Commonly used in lift stations, these pumps are durable and efficient.
• Positive Displacement Pumps: These are used in systems that require a consistent flow rate, regardless of the pressure.
• Maintenance Tip: Routine inspection and septic tank cleaning by a professional septic company can help extend the life of your pumps, reducing the need for costly septic tank repair.

Control Panel

The control panel is the brain of the lift station, managing the operation of the pumps based on the levels of wastewater in the wet well. It includes components like level sensors, alarms, and switches that automate the system’s operation. The control panel ensures that the pumps start and stop at the correct times, preventing both overflow and dry running.

Features:

• Level Sensors: These sensors monitor the wastewater level in the wet well and signal the pumps to activate when a certain level is reached.
• Alarms: In case of pump failure or system malfunction, alarms are triggered to alert maintenance personnel.
• Maintenance Tip: Regular testing of the control panel and its components can help avoid unexpected failures, keeping your septic system running smoothly.

Valves

Valves are essential for controlling the flow of wastewater within the lift station. They ensure that the flow is directed correctly and prevent backflow, which can cause system failure or contamination.

Common Types of Valves:

• Check Valves: These valves allow wastewater to flow in one direction, preventing backflow.
• Gate Valves: Used to isolate sections of the system for maintenance or repair.
• Maintenance Tip: Periodic inspection and maintenance of valves can prevent leaks and ensure that the lift station operates efficiently.

Piping

The piping within a lift station connects all the components, guiding the wastewater from the wet well to the pumps and eventually out to the sewer system or treatment plant. The pipes must be durable and corrosion-resistant to handle the harsh environment of a lift station.

Maintenance Tip: Regular inspection of the piping for leaks, cracks, or corrosion can prevent more serious issues that might require extensive septic tank repair.
