What Is Groundwater Infiltration?

Groundwater infiltration happens when water from the surrounding ground finds its way into a drainage system that was never designed to carry it — through cracked pipes, poorly sealed joints, a naturally high local water table, or a soakaway that’s no longer able to disperse water fast enough.

Once it’s in, that extra volume has to go somewhere. The usual consequences are overloaded pumps working overtime, drains that back up or block more often than they should, flooded gardens or outbuildings, and pipework that deteriorates faster than it otherwise would under constant, unintended flow.

Signs You Might Have Groundwater Infiltration

A few patterns are worth watching for, particularly after heavy rain:

  • Pumps or pump stations running far more frequently than usual
  • Tanks or chambers filling rapidly even with minimal household use
  • Wet or boggy patches appearing near inspection chambers
  • Drains running slow with no obvious blockage to explain it

Professional Groundwater Infiltration Solutions

We approach groundwater infiltration with four main tools, chosen to match how and where the water is getting in:

  • Gel injection repairs — sealing cracks and defective joints from within the pipe to stop water entering at the source
  • CCTV inspections — identifying exactly where infiltration is occurring along the run, rather than guessing
  • Pipe relays and trenchless repairs — restoring pipe integrity without excavating the garden or driveway above it
  • Pump station maintenance — keeping pumps running efficiently so they can cope with genuine peak flow, rather than fighting a constant background leak

Why Choose Flux Sewer Ltd?

We bring trusted, hands-on expertise built over more than a decade in the drainage industry, backed by CCTV and trenchless repair technology that lets us fix infiltration at its source rather than just pumping harder. We offer a fast response and free quotations across Devon & Cornwall, seven days a week.

Service Areas We Cover

Our groundwater infiltration work covers Plymouth, Plympton, Brixton, Sparkwell, and the surrounding areas within roughly five miles, as well as the wider Devon and Cornwall region.

The Importance of Timely Intervention

Groundwater infiltration rarely gets better on its own — left unaddressed, it typically gets worse, and more expensive, the longer it runs. Delayed action risks structural damage to the pipe network, steadily increasing repair costs, damp and mould hazards inside the property, and a measurable impact on property value if the issue is ever flagged during a sale.

If you’re seeing any of the warning signs above, get in touch for a CCTV survey before a manageable fix turns into a much bigger job.
