Understanding Geocellular Soakaway: A Comprehensive Guide

Understanding Geocellular Soakaway, Geocellular soakaway systems are becoming a popular solution for managing rainwater runoff. These systems are effective and eco-friendly, helping to prevent flooding and manage water sustainably. This guide explains what geocellular soakaways are, how they work, their benefits, and why you should consider installing one.

What is a Geocellular Soakaway?

A geocellular soakaway is an underground structure designed to manage rainwater runoff. It consists of interlocking plastic cells that form a large storage unit. This unit stores rainwater and allows it to slowly seep into the ground, reducing surface water runoff and minimizing flood risks.

Main Components

  1. Geocellular Units: Plastic cells made from durable materials like HDPE or polypropylene.
  2. Geotextile Membrane: A fabric that surrounds the cells to keep soil out while letting water through.
  3. Inspection Chambers: Access points for easy maintenance and inspection.

How Does a Geocellular Soakaway Work?

Here’s how a geocellular soakaway system operates:

  1. Collection: Rainwater from roofs and paved areas is collected and directed into the system.
  2. Filtration: Water passes through a filter to remove debris before entering the soakaway.
  3. Storage: Water enters the geocellular units, which can hold a large volume of water.
  4. Infiltration: Water slowly seeps from the units into the surrounding soil.
  5. Maintenance: Regular inspections ensure the system functions efficiently.

Benefits of Geocellular Soakaway Systems

Environmental Benefits

  • Flood Prevention: Reduces the risk of flooding by managing rainwater on-site.
  • Groundwater Recharge: Helps replenish groundwater levels by allowing water to seep into the ground.
  • Pollution Reduction: Filters pollutants from rainwater before it reaches natural watercourses.

Economic Benefits

  • Cost-Effective: Lower long-term maintenance and operation costs compared to traditional drainage systems.
  • Space Efficiency: Modular design allows installation in confined spaces.
  • Increased Property Value: Properties with effective drainage systems are more valuable.

Practical Benefits

  • Versatility: Suitable for residential, commercial, public, and infrastructure applications.
  • Ease of Installation: Quick and less labor-intensive installation process.
  • Durability: Made from strong materials that last long with minimal maintenance.

Applications of Geocellular Soakaway Systems

  • Residential Properties: Manages rainwater runoff from roofs and driveways.
  • Commercial Buildings: Handles large volumes of water from roofs and parking lots.
  • Public Spaces: Useful in parks and playgrounds to manage surface water.
  • Infrastructure Projects: Mitigates flooding risks in road construction and other developments.

Installation and Maintenance

Installation Steps

  1. Site Assessment: Determine the size and location for the soakaway.
  2. Excavation: Dig a pit to fit the geocellular units.
  3. Assembly: Assemble the units according to instructions.
  4. Lining: Line the pit with a geotextile membrane.
  5. Placement: Place the units in the pit and connect to drainage pipes.
  6. Backfilling: Cover the units with clean material and soil or permeable paving.

Maintenance Tips

  • Regular Inspections: Check the system regularly to ensure it’s clear of blockages.
  • Cleaning: Remove silt or debris from filters and inspection chambers.
  • Repairs: Fix any damage promptly to maintain system efficiency.
