The Science Behind Septic Tank Soakaway Kits

Septic tank soakaway kits are complete wastewater treatment systems that combine a septic tank with a soakaway (drainage field) to treat and disperse sewage from properties not connected to mains sewerage. These systems rely on natural biological processes and soil filtration to manage wastewater effectively. Here’s how they work:

How Septic Tank Soakaway Systems Function

Wastewater from toilets, sinks, showers, and appliances flows into the septic tank, undergoing a three-stage process:

1. Solid Separation: Heavy solids (sludge) settle at the bottom, while lighter materials (scum, like oils) float to the top.
2. Anaerobic Digestion: Bacteria inside the tank break down organic matter in an oxygen-free environment, reducing solid volume and partially treating the wastewater.
3. Effluent Dispersal: Treated liquid (effluent) flows to the soakaway (drainage field), where it percolates through soil layers for further natural purification.

Our septic tank soakaway kits feature a shallow drainage field (500mm below ground), optimized for clay-heavy or poor-draining soils. Unlike traditional systems with deeper drainage fields (1000mm+), our design ensures efficient effluent dispersal, reducing installation costs and environmental impact. The kits are sized according to British Water’s Flows and Loads guidance, with 3000L tanks for 1–4 bedrooms and 4000L tanks for 5–8 bedrooms, covering a wide range of property sizes.

Why Shallow Drainage Fields Work

In clay or rocky soils, water percolation is slow, and deep drainage fields often require larger areas, increasing costs. Our kits place the drainage field closer to the surface, where soil is less compact, improving effluent absorption. This design reduces installation time and complies with regulatory standards, making our septic tank soakaway kits ideal for diverse soil conditions across the UK.

Environmental Benefits

Our kits adhere to the Environment Agency’s General Binding Rules, preventing groundwater pollution. The shallow drainage field minimizes the risk of effluent reaching watercourses, protecting local rivers, streams, and coastal ecosystems, which is crucial for rural and tourism-driven areas.

Case Study: Septic Tank Soakaway Kit Installation

Background

In 2024, a campsite owner in Cornwall needed a septic tank soakaway kit to support their glamping site with four pods. With no mains sewer and clay-heavy soil, professional installation quotes averaged £18,500. They chose our £3,999 3–4 bedroom septic tank soakaway kit to save costs and simplify installation.

Methodology

The installation process included:

1. Site Assessment: The owner confirmed the site was over 30m from a public sewer and 50m from water sources, complying with Environment Agency regulations.
2. Installation: Using a 3-tonne digger, a local builder dug a shallow pit for the 3000L tank and a 500mm-deep trench for the drainage field. The kit was installed in 2.9 hours.
3. Inspection: A Building Control officer verified compliance with Approved Document H.

Results

The system was installed for under £4,200 (including digger rental), saving £14,300 compared to professional quotes. The shallow drainage field performed exceptionally in clay soil, with no pooling or odours after ten months. The owner reported easy maintenance and full regulatory compliance.

Conclusion

This case study demonstrates the affordability, ease, and effectiveness of our septic tank soakaway kits in challenging soil conditions, making them a top choice for campsites and rural properties.

Frequently Asked Questions (FAQ)

What are septic tank soakaway kits?

Septic tank soakaway kits are complete wastewater treatment systems that include a septic tank and a soakaway (drainage field) to treat and disperse sewage from properties not connected to mains sewerage.

Do I need planning permission for a septic tank soakaway kit?

Yes, new installations require planning permission and Building Control approval. Our kits comply with Approved Document H, simplifying the process.

Can I install the kit myself?

Yes, no experience is needed. The kit includes clear instructions, and installation takes about 3 hours with a 1.5–5-tonne digger. Many customers DIY or hire a local builder.

Will the kit work in clay or poor-draining soil?

Absolutely. The shallow drainage field (500mm deep) is designed for clay-heavy or poor-draining soils, ensuring efficient effluent dispersal.

How often should I maintain a septic tank soakaway kit?

Desludge the tank annually and inspect the drainage field for blockages. Follow the maintenance guide included with the kit.

What if my property is near a public sewer?

If within 30m of a public sewer, you may need to connect to it. If connection is impractical, our kits meet regulations for private systems. Contact your local water authority for guidance.

Why Our Septic Tank Soakaway Kits Outperform Traditional Systems
