What is a Soakwell System?
A soakwell is an underground structure designed to manage stormwater runoff by capturing water and allowing it to gradually be absorbed into the ground.
The soakwell system typically consists of a hole, lined with a porous material, that collects water from gutters, downpipes, and other drainage points around your property.
This system helps prevent flooding, reduce surface water runoff, and protect your property’s foundation from water damage.
1. Key Components of a Soakwell System
- Soakwell Chamber: The main component of the system that stores water temporarily before it is absorbed into the soil.
- Inlet Pipes: These pipes carry water from the surface (such as from your roof) into the soakwell chamber.
- Filter Media: The material (often gravel or other permeable substances) used to filter the water and prevent debris from clogging the soakwell.
Why Install a Soakwell System?
Installing a soakwell system offers several significant benefits for your property, particularly when it comes to water management. Below are the key reasons why you might consider installing a soakwell system on your property.
1. Prevents Flooding
Excess water from heavy rainfall can quickly accumulate and flood your property if there is no proper drainage system. Soakwell systems capture this water, divert it underground, and slowly release it into the soil, preventing pooling and flooding around your home.
Benefits of Flood Prevention:
- Avoids water damage: Soakwells help prevent water from pooling around your foundation and entering your home, which can cause structural damage.
- Preserves landscaping: By managing water flow, soakwells prevent erosion and water damage to your garden or outdoor spaces.
- Protects your driveway: Soakwells reduce the risk of driveway erosion by keeping water from collecting in low-lying areas.
2. Erosion Control
Without an efficient drainage system, heavy rain can cause soil erosion, particularly in areas where water tends to collect. Soakwells help absorb excess water, reducing the risk of soil erosion and protecting your landscape.
How Soakwells Help with Erosion Control:
- Distributes water: Instead of allowing water to flow rapidly over the surface and wash away soil, soakwells allow the water to seep into the ground.
- Prevents soil displacement: By managing stormwater runoff, soakwells prevent the loss of valuable soil from your garden or yard.
3. Groundwater Recharge
Soakwell systems allow rainwater to percolate back into the soil, which helps replenish groundwater supplies. This is an environmentally-friendly solution that reduces reliance on other water sources and helps maintain a healthy ecosystem.
Environmental Benefits:
- Replenishes underground water: Soakwells contribute to maintaining groundwater levels by allowing rainwater to naturally seep back into the earth.
- Reduces water wastage: By collecting stormwater and allowing it to be absorbed, soakwells reduce the need for using treated water for irrigation or other uses.
How to Install a Soakwell System
Installing a soakwell system can be a straightforward process if done correctly. Below are the necessary steps to follow to ensure a successful installation that provides long-lasting drainage solutions.
1. Assess Your Property’s Drainage Needs
Before installing a soakwell system, it’s essential to assess your property’s drainage needs. Consider factors such as the size of the area you need to drain, the type of soil, the amount of rainfall in your area, and the surface area from which water will run off.
Key Considerations:
- Property size: Larger properties may require multiple soakwells to effectively manage water.
- Soil type: Different soil types have different absorption rates, so your system should be sized based on this.
- Rainfall: Locations that receive frequent heavy rainfall require a more robust soakwell system.
2. Choose the Right Type of Soakwell
There are several types of soakwells available, and selecting the right one is essential for efficient drainage. Common types of soakwells include concrete, plastic, and gravel-filled chambers. The right choice will depend on your budget, soil type, and the volume of water you need to manage.
Types of Soakwells:
- Concrete Soakwells: Durable and long-lasting, concrete soakwells are ideal for larger installations and properties with more extensive drainage needs.
- Plastic Soakwells: Lightweight and easy to install, plastic soakwells are suitable for smaller properties or residential use.
- Gravel-filled Soakwells: Simple to construct and cost-effective, gravel-filled pits can be used for smaller-scale installations where professional help is not required.
3. Determine the Correct Size and Placement
Sizing and placement are crucial factors in ensuring your soakwell system functions properly. The size of the soakwell depends on the amount of water that needs to be managed, while the placement ensures water can flow easily into the system.
How to Determine the Correct Size:
- Rainwater runoff calculation: Use rainfall data and property size to calculate how much water needs to be managed and choose an appropriately sized soakwell.
- Multiple soakwells: For large areas, multiple smaller soakwells might be more efficient than a single large unit.
Placement Considerations:
- Near downpipes: Place the soakwell near downpipes to ensure rainwater flows directly into the system.
- Away from foundations: Ensure that the soakwell is located far enough from your property’s foundation to prevent water from seeping towards the building.
- Check local regulations: Some areas may have guidelines on the minimum distance that soakwells should be installed from property boundaries or other structures.
4. Dig the Soakwell Pit
After determining the size and placement of your soakwell, you’ll need to dig the pit. The pit should be wide and deep enough to accommodate the soakwell and allow for water storage and absorption.
Digging Tips:
- Use proper tools: A shovel or mechanical digger can be used, depending on the size of the pit.
- Ensure smooth sides: The sides of the pit should be smooth to avoid blocking water flow.
- Check the depth: Make sure the pit is deep enough to allow for adequate water storage and drainage.
5. Install the Soakwell and Connect the Pipes
Once the pit is ready, you can install the soakwell system. This involves placing the soakwell chamber in the pit, connecting the inlet pipes, and ensuring the system is secure and well-placed.
Installation Steps:
- Place the soakwell: Carefully place the soakwell chamber into the pit, making sure it fits snugly.
- Connect the inlet pipes: Attach the downpipe or other water inlet pipes to the soakwell chamber. Ensure the connections are secure to prevent leaks.
- Fill with gravel: If you’re using a gravel-filled soakwell, fill the chamber with gravel around the pipes to help with water filtration.
6. Test the System
After installation, it’s important to test the system to ensure it’s working as expected. Run water through the downpipe and check the soakwell for any signs of improper drainage or leakage.
Testing Tips:
- Check for slow drainage: Ensure that water drains quickly and that the soakwell is absorbing water as it should.
- Inspect for leaks: Look around the pipes and connections for any signs of leaks that may need to be sealed.
Maintenance of Soakwell Systems
To ensure your soakwell system continues to function effectively, regular maintenance is essential. Periodic checks and cleaning can prevent blockages and maintain optimal water absorption.
1. Regular Cleaning
Soakwells need to be cleaned periodically to prevent debris, dirt, or silt from clogging the system. You can clean the system by removing any leaves or debris that may have accumulated around the inlet or on top of the soakwell.
2. Inspect for Blockages
Over time, silt and sediment can build up inside the soakwell, reducing its capacity. Make sure to inspect the soakwell for blockages and clear them as needed.
Conclusion
A well-installed soakwell system is an effective solution for managing stormwater runoff, preventing flooding, and protecting your property from water damage.
By following the right steps, including proper sizing, placement, and maintenance, you can ensure your soakwell system performs optimally and provides long-lasting protection.
