The purpose of absorption beds is to allow sewage to be absorbed and cleansed by the soil. They are normally low-maintenance and do not emit any overpowering scents. However, an absorption bed may emit scents if it is not maintained properly or is not working well.

Among the frequent reasons for scents coming from absorption beds are:

Pipe blockages or clogs: If sewage cannot adequately flow through the absorption bed due to blocked or clogged pipes, smells may result.

Overflow: If the bed cannot handle the entire amount of sewage being produced, it may overflow, which may result in odours.

Contamination: The sewage being treated in the bed may emit aromas as it decomposes if it is severely contaminated or includes significant amounts of organic material.

Overall, an absorption bed should not emit any noticeable odours provided it is operating correctly and is kept in good condition. To make sure the bed is working properly, it is always a good idea to routinely inspect it and take care of any problems that might develop.
