Advanced Underground Stormwater Storage & Management Systems

High-Capacity Geocellular Tank Solutions for Sustainable Water Management

Geocellular Tanks are modern underground stormwater management systems designed to store, attenuate, infiltrate, or reuse surface water in urban and infrastructure developments. Flomax Pump Trading L.L.C supplies engineered geocellular tank systems that provide high storage capacity, structural strength, and long-term reliability while optimizing land use.

As urban areas continue to expand and surface water runoff increases, geocellular tanks have become a preferred solution for managing stormwater efficiently without consuming valuable above-ground space.

What Are Geocellular Tanks?

A geocellular tank system is a modular underground structure composed of high-strength plastic cells arranged to form a void space for water storage. These systems can achieve up to 95% void ratio, allowing large volumes of water to be stored within a compact footprint.

Geocellular tanks are installed below ground and connected to surface drainage networks, capturing stormwater runoff and controlling its release, infiltration, or reuse depending on project requirements.

Key Functions of Geocellular Tank Systems

Geocellular tanks supplied by Flomax are designed to perform multiple stormwater management functions, including:

  • Stormwater attenuation
  • Surface water detention and retention
  • Controlled discharge to drainage networks
  • Groundwater infiltration
  • Stormwater harvesting and reuse
  • Flood risk reduction

These functions support compliance with modern stormwater regulations and sustainable development goals.

Applications of Geocellular Tanks

Flomax geocellular tank systems are suitable for a wide range of applications, including:

  • Urban infrastructure projects
  • Commercial and mixed-use developments
  • Residential communities
  • Roads and highways
  • Airports and transportation facilities
  • Public parks and landscaped areas
  • Industrial developments
  • Car parks and podium decks

Their underground installation allows surface areas to remain usable for landscaping, parking, or pedestrian use.

System Design and Modular Configuration

Flomax geocellular tanks are supplied as modular systems, enabling flexible design and easy scalability.

System Components Typically Include:

  • High-strength geocellular modules
  • Geotextile or geomembrane wrapping
  • Inlet and outlet connections
  • Inspection and maintenance access points
  • Ventilation and overflow arrangements

Modules can be stacked and arranged to suit site constraints, storage volume requirements, and load conditions.

Structural Strength and Load-Bearing Capacity

Geocellular tanks supplied by Flomax are engineered to withstand significant vertical and lateral loads. When installed correctly and surrounded by appropriate backfill, these systems can support:

  • Vehicular traffic
  • Parking areas
  • Landscaping loads
  • Structural slabs and pavements

This high load-bearing capacity makes geocellular tanks suitable for installation beneath trafficked and developed areas.

Hydraulic Efficiency and Storage Performance

One of the major advantages of geocellular tanks is their exceptional storage efficiency. With a high void ratio, the system maximizes water storage while minimizing excavation volume.

Hydraulic performance benefits include:

  • Rapid stormwater capture
  • Controlled release to downstream systems
  • Reduced peak flow rates
  • Improved flood mitigation

These characteristics help protect drainage networks from overload during heavy rainfall events.

Stormwater Reuse and Sustainability

Geocellular tanks play a key role in sustainable water management strategies. Stored stormwater can be reused for applications such as:

  • Landscape irrigation
  • Toilet flushing
  • Cooling water
  • Non-potable industrial uses

By enabling water reuse, geocellular tanks reduce demand on potable water supplies and support environmental sustainability objectives.

Environmental Protection and Infiltration

When designed for infiltration, geocellular tanks allow stormwater to percolate gradually into the surrounding soil, replenishing groundwater and reducing surface runoff.

This controlled infiltration:

  • Minimizes erosion
  • Reduces downstream flooding
  • Improves natural water balance
  • Supports environmentally responsible development

Flomax systems can be configured to suit infiltration, detention, or retention requirements based on site conditions.

Installation Efficiency and Space Optimization

Geocellular tanks offer significant advantages in terms of installation and space utilization. Their lightweight modular design allows for:

  • Faster installation compared to traditional concrete tanks
  • Reduced excavation depth
  • Flexible layout around site constraints
  • Efficient use of confined urban spaces

This efficiency reduces construction time and overall project costs.

Maintenance and Access

Flomax geocellular tank systems are designed with inspection and maintenance access points, allowing periodic inspection, cleaning, and sediment removal where required.

Proper access ensures:

  • Long-term system performance
  • Compliance with maintenance requirements
  • Reduced risk of blockage or capacity loss

Compliance and Quality Standards

All geocellular tank systems supplied by Flomax are selected to comply with international engineering standards and local authority stormwater requirements. Materials used are resistant to chemicals, biological growth, and long-term environmental exposure.

This compliance ensures acceptance by consultants, authorities, and regulatory bodies.

Integration with Stormwater Systems

Flomax geocellular tanks integrate seamlessly with broader stormwater management infrastructure, including:

  • Polymer concrete channel drains
  • Slot drains
  • Oil separators
  • Silt traps
  • Underground drainage pipelines

This integration supports comprehensive and effective surface water control strategies.
