My sewage treatment plant smells, what can I do?
If your sewage treatment plant smells, there are a number of things that should be checked. It would be helpful to also understand what you should not put into a treatment plant as some things will harm or kill bacteria.
- Book a service from your local service company – If you haven’t had a recent service, then we would highly recommend having it checked by a professional
- Have your system emptied – Sludge build up should be removed at least once a year, if this is not happening then the system could be biologically overloaded
- Check that your treatment plant is running – If you have a system using an air blower, you should hear a slight humming sound from it, if not it may not be working
- Ensure you have not been using too many chemicals like bleach
- Ensure food waste is not going into the treatment plant
- Ensure any air vents have not been blocked – sewage systems need good air flow, it is a common mistake to block air flow when there are smells (to stop the smell getting out) however, the right way is to allow the gas to ventilate (preferably above your roof).
