The Science of Septic Tank Systems

Septic tanks are standalone wastewater treatment systems for properties not connected to mains sewerage, prevalent in rural Cornwall. They rely on natural biological processes to treat sewage. Here’s a detailed look at their operation:

How Septic Tanks Operate

Wastewater from household activities (toilets, sinks, showers) flows into the septic tank, where it undergoes a three-stage treatment process:

1. Solid Separation: Heavy solids (sludge) settle at the bottom, while lighter materials (scum, such as grease) float to the top.
2. Anaerobic Digestion: Naturally occurring bacteria break down organic matter in an oxygen-free environment, reducing the volume of solids and partially treating the wastewater.
3. Effluent Dispersal: The treated liquid (effluent) exits the tank into a drainage field, where it percolates through soil layers for further purification.

Our kits feature a shallow drainage field (500mm below ground), optimized for Cornwall’s varied soil conditions, including clay-heavy and rocky areas. Unlike traditional systems with deeper drainage fields (1000mm+), our design ensures efficient effluent dispersal in poor-draining conditions.

Advantages of Shallow Drainage Fields

Cornwall’s geology often includes clay or granite-based soils, which impede water percolation. Deep drainage fields struggle in such conditions, requiring larger areas and increasing costs. Our kits place the drainage field closer to the surface, where soil is less compact, improving effluent absorption. This design complies with British Water’s Flows and Loads guidance, ensuring optimal performance.

Environmental Impact

By adhering to the Environment Agency’s General Binding Rules, our kits minimize environmental risks. The shallow drainage field reduces the chance of effluent contaminating groundwater or nearby watercourses, protecting Cornwall’s rivers, such as the Tamar and Fal, and its coastal ecosystems.

Case Study: Septic Tank Installation in Cornwall

Overview

In mid-2024, a family in St Ives, Cornwall, needed a septic tank for their 3-bedroom coastal cottage. With no mains sewer connection and clay-heavy soil, professional installation quotes averaged £18,500. They opted for our £3,999 3–4 bedroom septic tank kit to save costs and simplify the process.

Methodology

The installation followed these steps:

1. Site Evaluation: The family 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 assembled in 2.8 hours.
3. Regulatory Approval: A Building Control officer inspected the system, confirming 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 well in clay soil, with no signs of pooling or odours after nine months. The family reported straightforward maintenance and full regulatory compliance.

Conclusion

This case study highlights the affordability, ease, and effectiveness of our septic tank kits in Cornwall’s challenging soil conditions, making them a top choice for rural and coastal properties.

Frequently Asked Questions (FAQ)

What are the General Binding Rules for septic tanks in Cornwall?

The Environment Agency’s General Binding Rules require septic tanks to discharge to a drainage field, not a watercourse, with a daily discharge under 2m³. Systems must meet British Standards (BS EN 12566). Our kits are fully compliant.

Do I need planning permission for a septic tank in Cornwall?

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

Can I install the kit myself?

Yes, no prior experience is needed. The kit includes detailed instructions, and installation takes approximately 3 hours with a digger. Many customers opt for DIY or hire a local builder.

Will the kit work in Cornwall’s clay or rocky soil?

Absolutely. The shallow drainage field (500mm deep) is designed for varied soil conditions, ensuring efficient effluent dispersal compared to deeper systems.

How often should I maintain the septic tank?

Desludge the tank annually and check the drainage field for blockages. Follow the maintenance guide provided with the kit for best results.

What if my property is near a public sewer?

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

Why Our Kits Outshine Traditional Septic Tanks

Traditional onion-style septic tanks require extensive excavations, concrete surrounds, and deep drainage fields, increasing costs and installation time. Our kits offer significant advantages:

• Shallow Excavation: 50% less depth reduces digging time and expense.
• No Concrete Needed: Eliminates costly concrete blankets, saving money.
• Compact Design: Smaller tanks fit postage-stamp gardens and tight spaces.
• Rapid Installation: 3 hours compared to days for traditional systems.

These features make our kits the best option for septic tank installation in Cornwall, particularly in areas with clay or rocky soils and limited space.

Regulatory Compliance in Cornwall

Our septic tank kits are fully compliant with:

• Environment Agency General Binding Rules: No discharge to watercourses, daily discharge under 2m³, and compliance with BS EN 12566 standards.
• Building Regulations Approved Document H: Proper sizing, installation, and drainage field design for safe operation.
• British Water Flows and Loads: Accurate tank sizing for 1–8 bedroom properties.

We provide all necessary documentation to support planning permission and Building Control applications, making the process straightforward.
