4600 L Septic Tank Kits: Easy, Affordable Off-Mains Drainage in the UK

Need a robust septic system but don’t have a huge budget or want a complex install? Our 4600 L septic tank soakaway kits are the perfect solution for UK properties. These kits are easy to DIY, saving you thousands, and are fully compliant with UK building regulations and sewage discharge regulations.

What’s Included?

  • Shallow dig, low profile 4600 L septic tank
  • 5 x 3-metre lengths of 110mm drainage pipe
  • 320mm inspection chamber
  • Drainage field crates
  • Free membrane

Simple, Electricity-Free Installation

  1. Dig a hole.
  2. Place the septic tank in the hole, fill ⅓ with water for stability.
  3. Install the inspection chamber and drainage crates.
  4. Connect pipework.
  5. Backfill with soil or gravel – no concrete needed!
  6. Connect the drainage field crate to the inspection chamber pipe.
  7. Cover the crates with the supplied membrane and backfill with soil.

Why Drainage Field Crates are Superior

Our drainage field crates offer a smaller footprint and faster drainage than traditional herringbone soakaways. They’re particularly effective in clay soil where drainage struggles, as they sit only 1.5 feet below ground.

Fast, Affordable Delivery

We offer approximately 7 working day UK delivery and it’s absolutely free!

HUGE Savings on Professional Installation

Save a minimum of £13,000 compared to hiring a septic tank installation firm. Our 4600 L septic tank soakaway kits are DIY-friendly or can be installed by your local builder or groundworker in approximately 3 hours.

Kits for Homes & Businesses

We tailor kits based on the number of bedrooms for residential use, and offer solutions for workshops, glamping sites, caravan parks, and more. Our kits are perfect for gardens, fields, or even under driveways (crates have a 60-tonne bearing load).

Fully Compliant for Peace of Mind

Our septic tank soakaway kits are approved by:

  • UK Building Control
  • Environment Agency
  • General Binding Rules

…making them easy to pass planning permission.
