Will emptying the tank dry the field out?

It removes the source of further solids and often gives temporary improvement, but it does not reverse soil that has already sealed. An assessment will establish how much capacity remains.

Wet Ground Over the Septic Field

Persistent wet ground over a disposal field means effluent is not soaking away as designed.

A disposal field should keep effluent below the surface where soil organisms complete treatment. When the surface stays wet in dry weather, the field is either receiving more than it can take or the soil interface has sealed.

Distinguish it from ordinary wet weather. Ground that stays soggy days after rain, smells, or has strikingly greener growth in defined strips is telling you something about the system rather than the season.

Contributing causes

Solids carry-over sealing the soil (biomat)
Overloading from high household water use
Stormwater or roof water entering the area
Compaction from vehicles or stock
Poorly draining soils or high groundwater
Uneven distribution across the laterals

Safe observations

Mark where the wet area starts and ends
Note whether it worsens after laundry days
Check whether roof downpipes discharge nearby
Photograph the area for the provider

What not to do

Do not drive on or excavate the field
Do not cover the area with fill or topsoil to hide it
Keep stock and children off the wet ground
