Overview of the 1-2 Bedroom Septic Tank Soakaway Kit

The 1-2 Bedroom Septic Tank Soakaway Kit is a complete wastewater management system designed for small properties with 1-2 bedrooms. Specifically, it includes:

Heavy-duty, shallow dig, low-profile septic tank (3000-litre capacity)
5 lengths of 110mm underground pipe
110mm connectors
12 drainage field crates
Free membrane

Furthermore, this kit is engineered for simplicity, requiring only 3 hours to install without concrete, electricity, or specialist experience. For example, it can be installed using a 1.5, 3, or 5-tonne digger, making it ideal for DIY enthusiasts or local builders. As a result, the compact 3000-litre tank has a smaller footprint than most UK septic tanks, perfect for postage stamp-sized gardens, clay soils, or high water table areas.

Key Benefits of the 1-2 Bedroom Septic Kit

Here’s why our 1-2 Bedroom Septic Tank Soakaway Kit stands out:

Affordable Pricing: At £3499, it’s significantly cheaper than professional installations costing £18,000.
Quick Installation: Takes just 3 hours, minimizing labour and disruption.
Compact Design: The 3000-litre tank fits in tight spaces, unlike bulky concrete “onion” tanks.
Regulatory Compliance: Approved by UK Building Control and Environment Agency, adhering to General Binding Rules.
Versatile Applications: Suitable for small homes, workshops, caravans, and campsites.
Clay Soil Compatibility: The drainage field sits 500mm below the grass, ensuring effective drainage in poor soil conditions.

Cost Saving Example: For instance, a professional septic tank installation for a 1-2 bedroom property costs £12,000–£18,000. However, our kit, at £3499, plus £500 for digger hire and £500 for labour, totals £4499—a saving of up to £13,501!

Types of Septic Tanks: Plastic, Fibreglass, and Concrete

Choosing the right septic tank material is critical for durability, cost, and ease of installation. Therefore, our wastewater solution uses high-density polyethylene (HDPE) plastic tanks, but let’s compare the three main options available in the UK: plastic, fibreglass, and concrete.

1. Plastic Septic Tanks (HDPE)

Plastic tanks, made from HDPE, are lightweight, corrosion-resistant, and increasingly popular for residential and commercial use. Specifically, they are ideal for this septic system.

Pros:
- Lightweight, simplifying transport and installation.
- Corrosion-resistant, ideal for wet or acidic soils.
- Affordable, typically £2000–£5000.
- Shallow dig designs reduce excavation costs.
- Certified to EN 12566-1 standards.
Cons:
- Less robust than concrete in high-traffic areas unless reinforced.
- May need anchoring in high water table areas.

2. Fibreglass Septic Tanks

Fibreglass tanks, made from glass-reinforced plastic, offer strength and durability, making them suitable for challenging ground conditions. However, they are less common for DIY kits.

Pros:
- Stronger than plastic, suitable for heavy vehicle traffic.
- Corrosion-resistant with a lifespan of 30–50 years.
- Lighter than concrete, easing installation.
Cons:
- More expensive than plastic (£3000–£7000).
- Can crack if improperly installed.
- Less widely available than plastic or concrete.

3. Concrete Septic Tanks

Concrete “onion” tanks are traditional, robust, and commonly used in large-scale applications but come with significant drawbacks. For example, they require deeper excavation than our system.

Pros:
- Extremely durable, lasting 50+ years.
- Resistant to buoyancy in high water tables.
- Suitable for heavy-duty applications.
Cons:
- Heavy, requiring cranes or heavy machinery.
- Needs a concrete surround, increasing costs (£1000–£2000).
- Deep excavation (2–3m) raises installation time and costs.
- Prone to cracking in unstable soils.
- Higher upfront cost (£5000–£10,000).

Comparison Table: Plastic vs. Fibreglass vs. Concrete Septic Tanks

Feature	Plastic (HDPE)	Fibreglass	Concrete
Cost	£2000–£5000	£3000–£7000	£5000–£10,000
Weight	Lightweight	Moderate	Heavy
Installation Time	3–6 hours	6–12 hours	1–2 days
Durability	25–50 years	30–50 years	50+ years
Corrosion Resistance	High	High	Moderate
Excavation Depth	Shallow (1–1.5m)	Moderate (1.5–2m)	Deep (2–3m)
Best For	DIY, small gardens, clay soil	Heavy traffic areas	High water tables, large sites

Consequently, our septic tank kit uses HDPE plastic tanks for their affordability, ease of installation, and suitability for most UK properties, making them ideal for small properties.

Cost Savings with the 1-2 Bedroom Septic Tank Soakaway Kit

Traditional septic tank systems, particularly concrete tanks, are costly and labour-intensive. However, our wastewater solution saves you £10,000–£15,000 through:

Shallow Excavation: Requires only 1–1.5m depth, compared to 3m for concrete tanks, reducing digger hire costs.
No Concrete Needed: Unlike concrete tanks, our HDPE tanks are backfilled with soil or gravel, saving £1000–£2000.
Compact Drainage Field: 12 drainage field crates create a high-void-ratio soakaway, requiring less land than herringbone soakaways.
DIY Installation: Professional installations cost £12,000–£18,000, but our £3499 kit can be installed by a DIYer or local builder.
Fast Setup: 3-hour installation minimizes labour expenses.
Clay Soil Performance: The drainage field at 500mm depth avoids dense clay layers, ensuring efficient drainage.

Therefore, our kit offers substantial savings while delivering reliable performance.

Why Drainage Field Crates Enhance the 1-2 Bedroom Septic Kit

Our kit includes 12 drainage field crates, which outperform traditional gravel-based soakaways. Specifically, here’s why:

High Void Ratio: 95% void space for faster effluent dispersal, compared to 30–40% for gravel soakaways.
Small Footprint: Ideal for small gardens, requiring less excavation.
Clay Soil Compatibility: Positioned 500mm below the surface, crates avoid heavy clay layers.
Durability: Robust plastic crates withstand soil pressure and are driveway-safe.
Easy Installation: Modular design simplifies setup.

Moreover, according to British Water, drainage field crates are a compliant solution for septic tank soakaways, ensuring regulatory approval.

What Are Attenuation Crates? Attenuation crates are modular plastic units that store and slowly release stormwater, preventing flooding. Consequently, they complement our septic system, offering a comprehensive wastewater and stormwater solution. Moreover, our attenuation crates are approved by UK Building Control and Environment Agency, ensuring compliance.

Septic Tank Size Guide

Furthermore, our tanks are sized according to British Water Flows and Loads, ensuring they meet your property’s needs.

Regulatory Compliance for the 1-2 Bedroom Septic Tank Soakaway Kit

Septic tank installations in the UK must comply with strict regulations. Therefore, our wastewater solution is approved by:

UK Building Control: Meets Part H of Building Regulations.
Environment Agency: Complies with General Binding Rules for small sewage discharges.
British Standards: Certified to BS 6297:2007+A1:2008 and EN 12566-1.

For instance, the General Binding Rules require septic tanks to discharge to a drainage field, not watercourses. As a result, our kit’s drainage field crates ensure safe effluent dispersal. Additionally, consult the Environment Agency for permits if your discharge exceeds 2 cubic metres per day or your property is near a public sewer.

Installing Your 1-2 Bedroom Septic Tank Soakaway Kit

Installing our septic system is straightforward and takes just 3 hours. Specifically, follow these steps:

Excavate: Dig a 1–1.5m deep hole for the tank, inspection chamber, and drainage field crates.

Connect Pipes: Use the 110mm pipes and connectors to link the tank to the house drain and drainage field.
Backfill: Fill with soil or gravel—no concrete required.
Test: Check for proper flow and leaks.

Moreover, our kits include detailed instructions, and our team at Builders Yard UK is available for support.
