How Many Soakaway Crates Do I Need?
Managing rainwater effectively is crucial, especially in areas prone to heavy rainfall or flooding. Soakaway crates are key to this, offering a practical solution for controlling surface water.
This blog will guide you through everything, from what soakaway crates are to how many you'll need for your project. By following this guide, you can ensure your land stays dry and water is managed sustainably.
So, whether you're planning a large-scale commercial project or looking to improve your home's drainage, keep reading to find out how to calculate the right number of soakaway crates for your needs.
Understanding soakaway crates
Soakaway crates are an essential part of modern drainage systems. They are designed to manage excess rainwater in both urban and rural settings.
Soakaway crates work by capturing rainwater and allowing it to slowly infiltrate back into the soil, reducing the risk of flooding and waterlogging. Made from sturdy, lightweight materials, soakaway crates can be easily installed underground and are an environmentally friendly alternative to traditional drainage methods.
There are two main types of soakaway crates: those used for filtration and those for attenuation.
Filtration crates are wrapped in a permeable geotextile, allowing water to seep into the surrounding ground gradually.
Attenuation crates are used to temporarily store water before it’s slowly released into the drainage system or a local watercourse.
Choosing the right type of soakaway crate depends on your specific project needs, including the soil type, the amount of space available and local planning regulations.
With a range of sizes and capacities available, soakaway crates offer a flexible solution for managing rainwater, slit capture, and various applications from residential gardens to large commercial developments.
How Many Soakaway Crates Do I Need?
Determining the right amount of soakaway crates for your project depends on several factors. Here are some things to consider:
1. Assess the Impermeable Area
What to Measure: Calculate the total area (in square metres) of impermeable surfaces that contribute to runoff. This includes roofs, driveways, patios and any other surfaces that don’t absorb water.
Why It Matters: The larger the impermeable area, the more water there is to manage, affecting the number of soakaway crates required.
2. Soil Type and Percolation Test
Conduct a Percolation Test: This test determines how quickly water can soak into the soil. Different soils absorb water at different rates, influencing the system's design.
Interpreting Results: Clay-heavy soils absorb water slowly, requiring more or larger crates, while sandy soils might need fewer crates due to faster absorption rates.
3. Local Regulations and Space Availability
Check Regulations: Some areas have specific requirements for stormwater management systems, including minimum distances from buildings and property boundaries. Typically, there is a requirement where possible for this location to be at least 5 metres from both lived in buildings and the boundary of the property. As a general exception it usually has to be a minimum of 3 metres where the above is not possible.
Consider Space: The physical space available for your soakaway system may also limit the number or size of crates you can use.
4. Calculation Example
A simple starting formula for calculating the number of soakaway crates you might need is:
Number of Crates = (Impermeable Area x Rainfall Intensity x Runoff Coefficient) / Crate Capacity
Expert Advice: For precise calculations and to account for local conditions, consulting with a drainage expert or engineer is recommended.
5. Planning for Excess
Safety Margin: Always plan for a slightly higher capacity than minimum calculations suggest to accommodate heavy rainfall events and potential miscalculations.
Additional considerations
When calculating the number of soakaway crates you need, there are broader considerations to ensure your soakaway system is as efficient and effective as possible.
1. Understanding Local Climate Patterns
Rainfall Intensity: The volume of rain your area receives can significantly impact the performance of your soakaway system. Areas with higher rainfall intensity might require a more robust system to handle the increased water volume.
2. Future-Proofing Your System
Anticipate Changes: Consider future developments or changes in land use that might affect runoff patterns. Planning for potential increases in impermeable surfaces can save you from costly upgrades down the line.
3. Environmental Considerations
Sustainable Drainage Systems (SuDS): Integrating your soakaway crates into broader SuDS can enhance environmental benefits, like improving water quality and supporting biodiversity.
4. Regular Maintenance Checks
Inspections: Periodic inspections and maintenance are vital to prevent blockages and ensure your soakaway system remains effective. This includes checking for sediment build-up and ensuring the inlet and outlet pipes are clear.
5. Expert Consultation
Tailored Solutions: Every site has unique characteristics. Engaging with drainage experts can provide customised advice, ensuring your soakaway system is optimised for your specific conditions and needs.
By taking these additional factors into account, you can ensure that your soakaway system not only meets current needs but is also prepared for future challenges, contributing to a more sustainable and resilient drainage solution.
Summary
Determining the number of soakaway crates required for your project requires an understanding of your site’s specific conditions, including the impermeable area, soil type, local climate patterns, and regulatory requirements. By taking these factors into account, you can ensure that your soakaway system is not only compliant with local regulations but also efficient and effective at managing stormwater runoff.
Remember, while this guide provides a solid foundation for planning your soakaway system, consulting with drainage professionals is invaluable. They can offer tailored advice, help navigate local regulations and ensure your system is designed to handle your specific needs.
