Choosing the right soakwell system is an essential decision for managing stormwater effectively. Whether you’re a homeowner looking to prevent flooding or a business owner seeking to enhance water drainage on your property, installing a soakwell system can significantly improve water management.
Soakwells capture and manage rainwater runoff, allowing it to be safely absorbed into the ground, preventing water damage, erosion, and flooding.
In this guide, we will walk you through the factors you should consider when selecting the right soakwell system for your home or business. If you want more details on how soakwells work and their benefits, feel free to go to my blog for additional insights.
Why You Need a Soakwell System
Before we get into the specifics of choosing a soakwell system, it’s important to understand why they are so crucial. Soakwell systems are designed to manage excess stormwater and rainwater runoff.
This water, if left unmanaged, can lead to a variety of issues, including flooding, erosion, water damage, and even the degradation of your property’s foundation.
Key Reasons to Install a Soakwell System:
- Prevents flooding: Excess water is absorbed into the ground rather than pooling on your property.
- Reduces soil erosion: Soakwells prevent water from washing away soil, preserving your landscaping and garden areas.
- Promotes groundwater recharge: Water captured by soakwells seeps back into the earth, helping replenish underground water reserves.
- Protects infrastructure: By directing water away from your property, soakwells protect your home or business foundation from water damage.
Factors to Consider When Choosing a Soakwell System
Choosing the right soakwell system depends on several factors, including the size of your property, the amount of water you need to manage, and the specific drainage needs of your location. Let’s look at the key elements you need to keep in mind.
1. Size of Your Property
The first factor to consider when choosing a soakwell system is the size of your property. Larger properties or those with extensive paved areas will require more substantial or multiple soakwells to handle the water runoff effectively.
How Property Size Affects Soakwell Selection:
- Large properties: Larger properties with extensive roofs or driveways will need a more robust system, possibly multiple soakwells, to manage the volume of water efficiently.
- Small properties: Smaller properties can typically get away with a single, appropriately sized soakwell.
- Impervious surfaces: Areas like driveways and patios that don’t allow water to be absorbed into the ground will need additional soakwell capacity.
2. Type of Soil
The type of soil on your property plays a critical role in determining the size and number of soakwells you’ll need. Soils with high permeability (e.g., sandy soils) allow water to absorb more quickly, while clay soils retain water for a longer period.
How Soil Type Affects Water Absorption:
- Sandy soil: Soakwells are highly effective in areas with sandy soil, as the water will percolate into the ground quickly.
- Clay soil: In clay-heavy areas, you may need larger or more soakwells to store and allow for slower absorption, as clay soil doesn’t allow water to seep in as easily.
- Loamy soil: Loam offers a good balance between drainage and water retention and can generally accommodate soakwells more easily.
3. Rainfall Levels in Your Area
The amount of rainfall your area receives will influence the size of the soakwell system required. If your region experiences heavy rainfall or regular storms, you may need a larger or more efficient soakwell system to manage the excess water.
How Rainfall Affects Soakwell Sizing:
- Heavy rainfall areas: If your area frequently experiences heavy rainfall, you’ll need a system designed to handle larger volumes of water quickly. This could mean opting for a larger soakwell or multiple systems spread across your property.
- Light rainfall areas: For areas with less frequent or intense rainfall, a smaller system may be sufficient to manage runoff.
- Stormwater runoff: Ensure your soakwell system can manage the peak volume of runoff expected during storms.
4. Location and Placement of the Soakwell
The placement of your soakwell system is another key consideration when choosing the right solution. Soakwells should be installed in areas where they can collect the most water but not interfere with the property’s structure or underground utilities.
Where to Place Your Soakwell:
- Near downpipes: Soakwells should be placed near downpipes to capture the water directly from your roof.
- Away from foundations: Soakwells should be located a reasonable distance from your home or business foundation to avoid water seeping towards the structure.
- Avoid utility lines: Ensure the soakwell is not placed near gas, electricity, or water pipes to avoid damaging them during installation.
5. Material and Design of the Soakwell
Soakwells are available in different materials, each with its own benefits. The material you choose will depend on factors such as your budget, the amount of rainfall your property receives, and the size of the system required.
Common Soakwell Materials:
- Concrete: Durable and long-lasting, concrete soakwells are ideal for larger properties and areas with heavy rainfall.
- Plastic: Lightweight and easier to install, plastic soakwells are a good option for smaller properties or residential homes.
- Gravel-filled: Gravel-filled pits are simple and cost-effective, often used for smaller-scale systems where professional installation may not be necessary.
6. Maintenance and Longevity
The maintenance required for your soakwell system should be factored into your decision-making process. Proper maintenance ensures that your soakwell continues to function effectively over time, preventing blockages and ensuring efficient water absorption.
Maintenance Considerations:
- Regular cleaning: Soakwells require periodic checks to remove debris and ensure they are functioning optimally.
- Debris filters: Some soakwells include a filter to prevent leaves, dirt, and other debris from clogging the system.
- Longevity: Choose a high-quality material that will last for years without needing significant repairs.
Steps to Install a Soakwell System
Once you’ve selected the right soakwell system, the next step is proper installation. While installing a soakwell can be a straightforward process, following these steps ensures its efficiency.
1. Evaluate the Site
Before installation, assess the soil and rainfall conditions, as well as the location of downpipes and utilities on your property. This evaluation will help determine the best type and size of soakwell system.
Site Assessment Tips:
- Measure the runoff area: Identify the surfaces where water runoff will occur (e.g., roof size, paved areas).
- Check for obstacles: Ensure there are no underground utilities or other obstacles that might interfere with installation.
2. Dig the Soakwell Pit
Once you’ve chosen the appropriate location, the next step is to dig a pit to house the soakwell. The size of the pit should match the size of the soakwell, allowing enough space for proper water absorption.
Digging Tips:
- Follow the soakwell size specifications: Ensure that the pit is deep enough to hold the soakwell and provide adequate water storage.
- Check local regulations: Some areas may have specific requirements for the depth and placement of soakwells.
3. Install the Soakwell and Connect the Pipes
With the pit ready, install the soakwell system according to the manufacturer’s instructions. Ensure that the inlet pipes are properly connected to the downpipes and that the soakwell is securely placed in the pit.
Installation Tips:
- Position the soakwell correctly: Ensure that the soakwell is placed level and that the inlet pipes are securely connected to the system.
- Fill with gravel (if needed): If you’re using a gravel-filled soakwell, fill the surrounding area with gravel for better filtration.
4. Test the System
Once the soakwell is installed, test the system by running water through the downpipe and checking for proper water flow and absorption. Ensure that water is being captured by the soakwell and that the system is working as intended.
Conclusion
Choosing the right soakwell system for your home or business is an important decision that can significantly improve stormwater management.
By considering factors such as the size of your property, soil type, rainfall levels, and the materials used, you can ensure that your soakwell system provides long-term drainage solutions.
Proper installation and maintenance will help you manage stormwater efficiently, preventing flooding, erosion, and water damage to your property.
