Services Lift Station Installation

Lift stations pump sewage from lower elevations to higher elevations or treatment facilities when gravity flow is not feasible, essential in Miami-Dade's flat topography requiring mechanical pumping (EPA). Lift station installation in Miami-Dade typically costs $15,000-$50,000 depending on pump capacity, station type, site conditions, electrical requirements, and installation complexity.

Standard submersible lift stations are used for locations requiring up to approximately 60 horsepower per pump, generally less than 24 feet wet well depth, and typically 2 pumps. Wet well/dry well configurations are used when lift stations require individual pumps greater than 60 horsepower, providing separation between pumping area and sump area for larger equipment.

Miami-Dade classifies all wet wells as Permit Required Confined Spaces requiring OSHA compliance, proper ventilation systems, and Class I Division 2 electrical classifications. All new or replacement lift station installations require mandatory prior written approval from Miami-Dade County director before construction (Miami-Dade County), including design review and permit approval (Florida DOH).

What is a lift station?

Lift stations (also called pump stations) are critical components of wastewater infrastructure that pump sewage from lower elevations to higher elevations or to treatment facilities when gravity flow is not feasible. They become necessary when topography, geological conditions, or location of service areas make gravity-fed sewer systems impractical.

How lift stations work:

• Wastewater flows into wet well (sump area)
• Pumps activate when wastewater reaches certain level
• Pumps push wastewater through force main pipe
• Wastewater discharged to higher elevation or treatment facility
• Control systems monitor pump operation and levels

When lift stations are needed:

• Flat topography preventing gravity flow
• Low elevation areas requiring elevation lift
• Long distances requiring pressure assistance
• Properties below sewer main elevation
• Multiple properties requiring centralized pumping
• Areas where gravity sewer not economically feasible

Components:

• Wet well: Sump area collecting incoming wastewater
• Pumps: Submersible or dry well pumps moving wastewater
• Control systems: Monitoring and automatic pump operation
• Force main: Pipe carrying pumped wastewater
• Electrical systems: Power supply and control panels
• Ventilation: Safety systems for confined spaces

Lift stations enable wastewater collection and transmission in areas where gravity systems cannot function. In Miami-Dade's flat topography, lift stations are essential for wastewater infrastructure.

Types of lift stations

Miami-Dade County design standards specify distinct lift station types:

Submersible Lift Stations:

• Used for up to approximately 60 horsepower per pump
• Generally less than 24 feet wet well depth
• Typically 2 pumps installed
• Cost-effective for moderate capacity needs
• Easier installation and maintenance
• Pumps installed directly in wet well

Wet Well/Dry Well Configurations:

• Used when pumps exceed 60 horsepower
• Separates pumping area (dry well) from sump (wet well)
• Allows for larger equipment and higher capacity
• Better accessibility for maintenance
• More complex design and installation
• Higher installation costs

Selection factors:

• Pump capacity requirements
• Wastewater flow volume
• Available space for installation
• Maintenance accessibility needs
• Long-term operational requirements
• Budget considerations

Station type selection depends on specific hydraulic demands, available space, and operational needs. Professional engineers determine appropriate configuration based on requirements.

Installation process step-by-step

Lift station installation follows structured process:

Step 1: Site evaluation and design

Professional evaluation assesses site conditions, evaluates topography and elevation changes, determines pump capacity requirements, checks electrical service availability, identifies any site constraints, and verifies compliance feasibility. Engineering design creates station specifications meeting Miami-Dade standards.

Step 2: Permit acquisition

Apply for Miami-Dade County permit including design plans, pump specifications, electrical schematics, site plans, and required documentation. Mandatory prior written approval from county director required before construction. Permit process ensures compliance with design standards.

Step 3: Excavation and construction

Excavate area for wet well and station components including digging to required depth, ensuring proper positioning, preparing base for components, and ensuring adequate space for equipment. Construction may require bypass pumping if existing systems must remain operational.

Step 4: Wet well installation

Install wet well structure including precast concrete or constructed wet well, proper depth and sizing, inlet connections, and structural support. Wet well must meet confined space and ventilation requirements.

Step 5: Pump and equipment installation

Install pumps and related equipment including submersible pumps or dry well pump installation, force main connections, check valves, and pump controls. Equipment installation requires proper alignment and connections.

Step 6: Electrical and control systems

Install electrical systems including control panels, wiring, monitoring systems, alarms, and backup power if required. Control systems typically housed in separate electrical building per Miami-Dade preferences. Electrical systems require Class I Division 2 classification for wet wells.

Step 7: Ventilation systems

Install ventilation systems for confined spaces including wet well ventilation, control building ventilation if applicable, and compliance with OSHA confined space requirements. Ventilation essential for safety and compliance.

Step 8: Final inspection and commissioning

Miami-Dade inspector conducts final inspection verifying compliance with approved plans, checking proper installation, ensuring system function, and approving station for operation. System must pass inspection and commissioning before becoming operational.

Following proper installation process ensures compliance, proper function, and long-term reliability. Professional contractors and engineers manage entire process meeting all requirements.
