To manage overflow, whether from rain or drainage systems, one digs a structure called a soak hole, soakaway, or soak pit. The efficiency of a soak hole in releasing water into the soil is directly proportional to its depth.
The quantity of water it must manage, as well as soil type and local restrictions, are factors that impact its depth. Having a good grasp of these factors guarantees that the soak hole operates at its best while still meeting environmental regulations.

How Deep Should A Soak Hole Be?
The depth of a soak hole, also known as a soakaway or soak pit, typically depends on several factors such as soil type, local regulations, and the amount of rainfall or water runoff it needs to handle. Generally, soak holes are dug to a depth where the bottom is permeable enough to allow water to percolate into the surrounding soil.
Here are some general guidelines:
- Soil Type: If the soil is well-draining (sandy or loamy), the soak hole might need to be deeper compared to less permeable clay soils.
- Regulations: Local regulations may specify minimum depths for soak holes based on environmental considerations and water management standards.
- Water Volume: The depth also depends on how much water the soak hole needs to handle. It should be deep enough to accommodate significant volumes during heavy rainfall without overflowing.
As a rough estimate, soak holes are often dug to a depth of at least 1.5 to 2 meters (5 to 6.5 feet), but this can vary widely. It’s advisable to consult local authorities or a professional engineer to determine the appropriate depth for your specific situation.
When To Install Soakwell?
Installing a soakwell, also known as a soak pit or soakaway, is typically recommended when you need to manage excess water efficiently, such as from roof runoff, driveways, or other paved surfaces. Here are some situations when installing a soak well might be necessary or beneficial:
- Water Management: If you experience pooling or flooding in your yard or around your property after rainfall, a soak well can help to alleviate this by allowing excess water to infiltrate into the ground.
- Compliance: In some areas, local regulations may require the installation of soakwells to manage stormwater runoff and prevent environmental damage.
- Preventing Erosion: Soakwells can help prevent soil erosion by controlling where water drains and reducing the impact of runoff on the landscape.
- Improving Drainage: Installing soakwells can improve the overall drainage of your property, especially if you have clay soil or other types of soil that drain poorly.
- New Construction or Renovation: During new construction or renovation projects, it’s often a good time to install soakwells to integrate them into the design and ensure effective water management from the outset.
It’s advisable to consult with a local landscaper, drainage specialist, or building professional to assess your specific needs and determine the best time and method for installing soakwells on your property.
Why Do We Need Soakwells?
Soakwells, also known as soak pits or soakaways, serve several important purposes related to managing water runoff and improving drainage:
- Water Management: They help manage excess water from rainfall, preventing waterlogging and reducing the risk of flooding in yards, driveways, and other paved areas.
- Environmental Protection: Soakwells facilitate the infiltration of water into the ground, which helps recharge groundwater levels and reduces the strain on stormwater systems. This can prevent pollution of water bodies by reducing the amount of sediment, pollutants, and nutrients carried by runoff.
- Preventing Erosion: By controlling where and how water drains, soakwells can help prevent soil erosion, preserving the stability and integrity of the landscape.
- Improving Soil Health: Enhanced drainage provided by soakwells can improve soil aeration and reduce soil compaction, promoting healthier vegetation and landscaping.
- Compliance: Many localities require the installation of soakwells to comply with regulations aimed at managing stormwater runoff and protecting the environment.
Soakwells are essential for sustainable water management, protecting properties from water damage, and promoting environmental stewardship by reducing the impact of urban development on natural water systems.
How Much To Install A Soak Well?
The cost of installing a soak well can vary widely depending on several factors, including:
- Size and Depth: Larger and deeper soakwells will generally cost more to install than smaller ones.
- Material: The material used for the soakwell, such as concrete, plastic, or prefabricated units, will affect the cost.
- Location: Accessibility to the installation site, soil conditions, and local labour rates can influence the overall cost.
- Local Regulations: Compliance with local building codes and permits may add to the cost.
- Additional Work: If excavation or other preparatory work is needed, this can also affect the total installation cost.
As a rough estimate, installation costs for a standard residential soakwell can range from a few hundred to several thousand dollars. It’s recommended to get quotes from local contractors or specialists who can assess your specific needs and provide a more accurate cost estimate based on your location and project requirements.
How To Locate Soakwell?
Locating a soak well involves several steps to ensure it is placed effectively for optimal drainage and compliance with local regulations. Here’s a general guide on how to locate a soak well:
- Site Assessment: Assess your property to identify areas prone to water pooling or runoff, such as near downspouts from roofs, driveways, or low-lying areas where water tends to collect.
- Consult Regulations: Check local building codes and regulations regarding the placement of soakwells. Regulations may specify setback distances from property lines, buildings, and utility lines.
- Determine Size: Calculate the size of the soakwell needed based on the amount of runoff it will receive. This can depend on factors such as roof area, paved surfaces, and local rainfall intensity.
- Dig Test Holes: Before finalizing the location, dig test holes to assess soil conditions. Ensure the soil is permeable enough to allow water to infiltrate into the ground effectively.
- Consider Access: Ensure the soakwell is accessible for maintenance and inspection. It should be located where it can be easily reached for cleaning or repairs if needed.
- Mark and Measure: Once the location is determined, mark the area where the soakwell will be installed. Measure and mark out the dimensions according to the size of the soakwell unit.
- Installation Preparation: Prepare the site by excavating the area to the required depth and dimensions for the soakwell installation. Follow the manufacturer’s guidelines or consult with a professional for specific installation requirements.
- Install Soakwell: Finally, install the soakwell unit according to the manufacturer’s instructions or industry standards. Ensure it is properly connected to drainage pipes or runoff sources and backfilled with appropriate materials.
By following these steps, you can effectively locate and install a soakwell to manage excess water and improve drainage on your property. If in doubt or for complex installations, consulting with a drainage specialist or contractor is advisable.
Conclusion
To improve drainage around your property and manage extra water from rainfall, installing a soak well is a sensible alternative.
Effectively reducing water pooling, preventing soil erosion, and contributing to sustainable water management practices can be achieved by meticulously choosing the location based on on-site evaluation, taking local rules into account, and assuring correct installation.
In addition to improving the beauty and security of a property, a strategically located soakwell can help with environmental stewardship by decreasing the amount of stormwater runoff that harms natural water systems.
To get the most out of the installation and make sure it complies with all applicable building laws and regulations, it’s a good idea to get in touch with local specialists.
