In this article, we'll present 7 maintenance tips that all homeowners or facility managers should observe to keep their wastewater system in top operating condition — and prevent expensive repairs or stinky odors.
1. Keep an Eye on What You Flush
This is the onsite sanitation system's golden rule. Septic tanks and biodigester septic system are designed to treat human waste and biodegradable toilet paper alone. Flush non-biodegradable things such as:
- Sanitary pads
- Baby wipes
- Diapers
- Cotton swabs
- Plastics or condoms
...result in clogs, backups, or even long-term system damage.
Even in biodigester systems, where waste breaks down more effectively by bacteria, non-food items interfere with digestion or trap outflow.
✅Tip: Put up a small sign next to the toilet to remind guests and household members what not to flush.
2. Don't Pour Harsh Chemicals into the Drain
Chemical Bleach, drain cleaners, and disinfectants, as well as other household chemicals, are the one which destroys the good bacteria in septic tanks and biodigesters. These organisms are responsible for the waste digestion. With time, chemical saturation can cause bad odors, poor digestion, or system failure.
Use biodegradable or environmentally friendly cleaning products instead. They are safe for your system and more earth-friendly.
3. Regular Inspections Schedule
Even systems low in maintenance can benefit from occasional check-ups. Employ a licensed plumber or technician to check:
- Tank levels (particularly septic tanks)
- Inlet/outlet pipes
- Gas vents
- Effluent discharge quality
- Leaks or cracks
· Biodigester systems rarely need desludging, but they should still be checked every 2–3 years to keep everything running smoothly.
4. Use Bacterial Enzymes (If Recommended)
A few manufacturers or system suppliers can also suggest the use of bacterial enzyme additives — particularly for new or dormant systems. Additives aid in getting microbial processes going and correcting imbalance if it has been caused.
But use only authorized products and be very careful to follow instructions. Not all systems need them.
✅ Bonus: These can also assist in minimizing odor and accelerating digestion rate in septic tank as well as biodigester tanks.
5. Avoid Heavy Vehicles from the Tank Region
This is perhaps the most recurrent and frequent (and costly) error cause big trouble. Placing automobiles or heavy equipment over a hidden septic or biodigester tank can cause troubles such as:
- Crack the tank
- Damage inlet/outlet pipes
- Collapse underground chambers
· Clearly mark out the location of the tank and never put rooms, courtyard, sheds, or permanent objects on the top of it.
6. Divert Rainwater and Surface Runoff
Excess water entering the tank space can overload the system, particularly during monsoons. If ground gets saturated, it can hinder correct effluent absorption (in septic tanks) or interfere with biodigester flow.
Ensure roof drains, stormwater pipes, and landscaping divert water away from the tank space.
✅Tip: Slightly elevate the tank installation space high or install drainage trenches to avoid waterlogging.
7. Educate Everyone in the Household
Even the best septic or biodigester system will fail if abused by those who occupy the dwelling. Educate everyone — including children and visitors — on:
- What to flush
- What not to pour down the drain
- How to recognize the early warning signs (such as gurgling noises, sluggish drains, or odors)
The better everyone knows, the less you'll have to be surprised about.
Bonus: Signs Your System Needs Attention
- Bad odor around drains or tank space
- Clogged toilets or sinks
- Wet spots in yard (potential leaks)
- Gurgling noises in pipes
Should you see any of these, don't hesitate. Call a professional for inspection and action.
Conclusion
Taking care of a septic or biodigester septic tank system doesn't have to be difficult. With a few intelligent habits and regular inspections, you can prevent serious problems, increase the lifespan of your system, and maintain a clean, odor-free space near your house.
No matter if you're working with a high-tech biodigester or an old-fashioned tank, these 7 tips will keep you ahead of trouble — and save you money in the long term.
