4 Person Septic Tank Kit – Your Easy, Affordable Off-Grid Sewage Solution

Need a reliable sewage system for your UK home but don't want to break the bank? Our 4-person septic tank soakaway kits provide a cost-effective, DIY-friendly solution that checks all the boxes for UK regulatory approval.

What You'll Get

  • Shallow dig, low-profile septic tank: For minimal disruption to your property.
  • 5 x 3-meter lengths of 110mm single-socket pipes: Everything you need for easy connection.
  • 1 x 320mm inspection chamber: Keeps things accessible for maintenance.
  • Drainage field crates: Space-saving and efficient soakaway technology.

UK Compliance Guaranteed

Our septic tank soakaway kits are fully approved by UK Building Control, the Environment Agency, and the General Binding Rules. This means you'll have no problems securing planning permission and staying on the right side of sewage discharge regulations in the UK.

Unbeatable Simplicity

We believe off-grid sewage solutions shouldn't be complicated. Our kits are designed for installation by a local builder, groundworker, or even a confident DIYer. Here's the simple process:

  1. Dig a hole
  2. Place the tank, inspection chamber, and drainage crates
  3. Connect the pipes
  4. Backfill with soil or gravel

No concrete. No electricity. No fuss.

Better Than Traditional Soakaways

Drainage field crates offer a major advantage over old-school herringbone soakaway systems – a super-compact footprint. That makes our kits perfect for properties with limited space.

Fast, Free UK Delivery

Get your septic tank soakaway kit delivered to your door in about 7 working days, with free delivery across the UK!

Install in Hours, Save Thousands

A typical septic tank soakaway kit takes just 3 hours to install. Compare that to the £12,000 - £15,000 cost of hiring an installation company, and you could save a whopping £13,000 minimum!

Works Even in Clay Soil

Drainage field crates sit just 1.5 feet below ground level, making them a lifesaver in areas with clay soil or poor drainage where traditional systems struggle.

Flexible Sizing for Every Property

We offer kits tailored to the number of people using the system. Find the perfect fit for your household, with sizes including:

  • 4 Person Septic Tank Kit
  • 5 Person Septic Tank Kit

Commercial Properties? No Problem!

Our septic tank kits aren't just for homes. They're a brilliant solution for businesses, glamping sites, campsites, and anywhere that needs off-grid waste management.
