What Is a Septic Tank System in London?

Septic tank system London - tank and pipework layout

A septic tank system is an off-mains wastewater solution used where properties are not connected to the main sewer. Wastewater flows into the tank, solids separate, and treated liquid is discharged to a suitable drainage solution (such as a soakaway/drainage field) depending on the site setup.

Our septic tank installaion service in London helps you choose the right tank size and installation approach for your property. We handle excavation, tank placement, pipe connections, and tidy completion — with clear advice on correct use and maintenance.

  • ✓ New septic tank installaion and replacement
  • ✓ Drainage connections and pipework improvements
  • ✓ Soakaway / drainage field solutions (where required)
  • ✓ Repairs for smells, overflows and leaks
  • ✓ Practical advice and clear handover
