Soakaways in Cornwall: Smart Solutions for Sustainable Drainage

In Cornwall, where the climate can be unpredictable, implementing a soakaway system can significantly enhance drainage efficiency. Soakaways in Cornwall are essential for managing rainwater runoff, preventing flooding, and reducing the risk of water damage to your property. This article examines the role of soakaways as an effective drainage solution in Cornwall, detailing their functional benefits, installation requirements, and long-term maintenance considerations.

What are Soakaways?

Soakaways are essential components in modern drainage systems, designed to manage excess water from rainfall and wastewater. They are commonly used in both residential and commercial properties as a sustainable drainage solution. Soakaways work by allowing water to seep into the ground, reducing the burden on sewage treatment plants and septic tanks.  This helps to prevent flooding, reduce stormwater runoff, and promote groundwater recharge.

Benefits of Soakaways

Soakaways are a popular method for managing surface water drainage, especially in regions like Cornwall. As communities continue to seek sustainable solutions to manage stormwater, soakaways represent a practical and environmentally friendly option that aligns with Cornwall’s commitment to preserving its natural beauty and ecosystems. Here are some key benefits of using soakaways:

1. Prevent Flooding: Cornwall is prone to heavy rainfall and flooding, particularly in winter months. Soakaways help mitigate the risk of surface water flooding by allowing rainwater to infiltrate into the ground, reducing runoff and alleviating pressure on drainage systems.
2. Environmental Sustainability: Soakaways help to reduce surface water runoff, which can carry pollutants into local water bodies. By allowing water to infiltrate into the ground, soakaways help to filter out contaminants, protecting streams, rivers, and lakes from pollution.
3. Groundwater Recharge: Soakaways contribute to the replenishment of groundwater supplies. By allowing rainwater to percolate into the soil, they help maintain the water table, which is essential for local ecosystems and drinking water supplies.
4. Reduced Erosion: Excessive surface runoff can lead to soil erosion, especially on sloped terrains common in Cornwall. Soakaways help slow down the movement of water, allowing it to penetrate the soil rather than wash it away, thus protecting the landscape.
5. Cost-Effective Solutions: Installing a soakaway can be a more affordable option compared to traditional drainage systems. They often require less infrastructure, reducing both installation and maintenance costs over time.
6. Space Efficiency: Soakaways can be designed to fit various spaces, making them suitable for residential, commercial, and agricultural applications. They can be integrated into gardens, driveways, and other areas where space is limited.’
7. Sustainability: Utilising soakaways aligns with sustainable development practises. They promote the concept of managing water sustainably and can be an integral part of a wider sustainable drainage system (SuDS).
8. Low Maintenance: Once installed, soakaways typically require minimal maintenance. Regular checks for blockages and sediment accumulation may be necessary, but overall upkeep is generally less intensive compared to traditional drainage systems.
9. Regulatory Compliance: With increasing environmental regulations aimed at reducing surface water runoff and promoting sustainable practises, implementing soakaways can help property owners and developers comply with local planning requirements.
10. Climate Change Resilience: As climate change leads to more erratic weather patterns and intense rainfall events, soakaways provide a proactive approach to managing increased precipitation. They support resilience strategies for both urban and rural areas in Cornwall.

The Soakaway Installation Process in Cornwall

Installing a soakaway in Cornwall is an essential step for effective drainage management, especially given the region’s unique geology and climatic conditions. Here’s a step-by-step guide to the soakaway installation process:

Step 1: Assess Your Property

Before any installation begins, a thorough site assessment is crucial. This involves:

• Soil Testing: Conduct a percolation test to evaluate the soil’s drainage capacity. In Cornwall, the soil can vary significantly. Different soils have varying absorption rates, which will influence the soakaway’s design. Clay soils, for example, may require larger soakaways due to their slower absorption rates.
• Identifying Drainage Needs: Determine the volume of water that needs to be managed based on the size of the property and the expected rainfall.
• Assessing Local Regulations: Check local planning regulations and guidelines to ensure compliance with any environmental requirements.

Step 2: Design Your Soakaway

A properly designed soakaway considers factors such as:

• Size and Depth: The size of the soakaway will depend on the volume of water to be managed and the results of the soil tests. A larger soakaway may be necessary in areas with poor drainage.
• Location: Position the soakaway at least 5 metres away from buildings, boundaries, and other structures to avoid water damage and ensure effective drainage.
• Materials: Choose appropriate materials for the soakaway, such as perforated pipes and gravel, which facilitate water infiltration.

Step 3: Digging and Installation

Once the design is finalised, the installation can begin:

1. Excavate the Site: Excavate a hole according to the planned dimensions. The depth and width of the pit should align with the designed size of the soakaway.
2. Install the Base: Ensure the base of the pit is level and compacted to support the structure. Place a layer of coarse gravel or crushed stone at the bottom of the pit to aid in water drainage.
3. Add Perforated Pipes: Lay perforated pipes in the pit, ensuring they are properly sloped to facilitate water flow.
4. Adding Additional Layers: Cover the pipes with more gravel, allowing enough space for water to seep through while preventing soil from clogging the system.
5. Backfill and Final Grading:  Grade the surface of the soil to direct any surface water towards the soakaway.

Step 4: Testing and Maintenance

After installation, test the soakaway to ensure water drains as expected. Regular maintenance includes checking for blockages and sediment build-up to ensure optimal performance.

Innovations in Soakaway Design and Practise Across Cornwall
