If you’re a homeowner in Bournemouth or the surrounding areas, managing rainwater runoff effectively is crucial to maintaining a dry, functional property. One of the most effective solutions available is a soakaway system. At Bournemouth Drains24, we provide expert soakaway installation services that help prevent flooding and improve drainage. In this blog post, we’ll explore what a soakaway is, its benefits, the installation process, and helpful tips for creating your own soakaway.
What is a Soakaway?
A soakaway is an underground structure designed to collect and manage surface water runoff, particularly during heavy rainfall. By allowing rainwater to infiltrate gradually into the ground, soakaways help prevent flooding and reduce pressure on existing drainage systems. Modern soakaways often use interlocking plastic crates wrapped in geotextile membrane, which are much more efficient and easier to maintain than older systems filled with gravel.
Key Benefits of Soakaway Systems
- Flood Prevention: Soakaways effectively manage surface water, significantly reducing the risk of flooding around your property.
- Environmental Protection: By promoting natural groundwater recharge, soakaways help maintain local ecosystems and promote sustainable water management.
- Cost-Effective: While the initial installation may require an investment, soakaways can save money over time by reducing the need for expensive repairs related to flooding or drainage issues.
- Minimal Maintenance: Once properly installed, soakaways generally require little upkeep, especially when supplemented with pre-filters to catch debris.
The Soakaway Installation Process
Installing a soakaway can be straightforward if you follow these key steps:
1. Select the Right Location
Choosing the correct site for your soakaway is crucial. Ideally, it should be located at least 5 meters away from your home and any retaining walls. Additionally, it’s essential to avoid placing it above any underground services, such as gas, water mains, or drainage pipes. If you’re unsure about potential hazards, consult your local authority for site plans.
2. Conduct a Soil Percolation Test
Before proceeding, perform a soil percolation test to ensure your soil is suitable for a soakaway. Soils like clay with low permeability may not work well. A percolation test will help you determine if your site is appropriate for this type of drainage solution.
3. Dig Out the Site
Excavating the area for the soakaway requires careful planning. You’ll want to dig a hole large enough to accommodate the soakaway crates and allow space for backfill. For example, if you’re using a Geocell 1m3 Soakaway Crate Kit, you’ll need to dig a hole measuring approximately 1530mm long, 970mm wide, and 1600mm deep.
4. Install a Pre-Filter
While not strictly necessary, fitting a pre-filter can extend the life of your soakaway. A silt trap, installed before the crate, captures dirt and waste before it enters the soakaway, preventing clogs.
5. Prepare the Base
After excavation, clear the pit of any roots, stones, or other debris. Add a 150mm layer of 20mm pea shingle or sharp sand to the base, ensuring a stable foundation for the soakaway crates.
6. Install the Soakaway Crates
Before placing the soakaway crates in the pit, line the hole with a geotextile membrane to prevent soil from blocking the system. Once the crates are installed, make sure they are secured together properly.
7. Connect the Inlet Pipe
Depending on your soakaway design, connect the inlet pipe to direct rainwater toward the soakaway. Ensure the membrane is properly sealed around the pipe to prevent dirt from entering the system.
8. Backfill the Soakaway
Fill the area around the soakaway crates with 150mm of sharp sand or pea shingle, followed by soil to create a level surface. If you’re installing the soakaway beneath a grassy area, re-lay the sod on top.
