Septic Tank & Drain Cleaner for Australian Wastewater Systems
Professional Bacterial Treatment for Septic Tanks, Grease Traps & Blocked Drains

Persistent odours, slow drains, grease build-up and sludge accumulation are common indicators of an unbalanced wastewater treatment system. Septic Science Septic Clean is a high-performance bacterial treatment formulated to restore biological activity in septic tanks, grease traps, household drains and onsite wastewater systems.
Using concentrated freeze-dried bacteria cultures, Septic Clean helps replenish depleted microbial populations responsible for breaking down fats, oils, grease (FOG) and organic solids within wastewater systems. Regular maintenance dosing assists in reducing sludge accumulation, improving drain flow and minimising unpleasant odours throughout residential and commercial wastewater infrastructure.
Suitable for:
-
- Septic tanks
- Grease traps
- Household drains
- Wastewater treatment plants
- Composting toilets
- Greywater systems
- Rural and off-grid properties
Advanced Bacterial Drain & Septic Treatment
Wastewater systems rely on healthy bacterial colonies to function efficiently. Seasonal temperature changes, household cleaning chemicals, medications and excessive water loading can disrupt the biological balance inside septic systems.
When beneficial bacteria populations decline, systems may begin to exhibit:
-
- Drain odours
- Slow or blocked drains
- Grease accumulation
- Excess sludge build-up
- Foaming treatment systems
- Reduced treatment efficiency
Septic Science Septic Clean introduces specialised bacteria strains designed to rapidly activate on contact with water and begin digesting accumulated organic waste materials throughout the system.
The bacteria work progressively through:
-
- Kitchen drains
- Bathroom drains
- Grease traps
- Septic tanks
- Treatment chambers
- Absorption trenches
This biological cleaning action assists in restoring system balance naturally without harsh chemicals.
How Septic Clean Works
Once introduced into the wastewater stream, the freeze-dried bacteria activate within minutes and begin multiplying rapidly. These bacteria digest organic solids and fats that contribute to sludge accumulation and drain blockages.
Unlike chemical drain cleaners that may damage wastewater ecosystems, bacterial treatments support the natural biological processes already occurring within the system.
Routine maintenance treatment may help:
-
- Reduce septic sludge accumulation
- Improve grease trap performance
- Control wastewater odours
- Assist drain-line cleaning
- Improve overall wastewater efficiency
- Support septic trench performance
Recommended Septic Maintenance Dosage
For ongoing maintenance:
-
- Flush one 20g scoop monthly down a toilet
- Apply additional doses through kitchen and household drains
- Rotate application points monthly through bathrooms, laundries and sinks
- Use cool to warm water only
For systems experiencing odours, chemical shock or poor performance, weekly dosing for 4 weeks is recommended to help restore microbial balance.
Ideal for Homes Using Harsh Cleaning Products
Many common household cleaning chemicals negatively affect septic bacteria populations. Anti-bacterial cleaners, bleach products and disinfectants can severely disrupt wastewater treatment performance.
Septic Clean is particularly beneficial where systems have been impacted by:
-
- Bleach and chlorine products
- Anti-bacterial cleaners
- Heavy detergent use
- Medication use
- Chemotherapy treatment
- Long periods of low system activity
Safe Cleaning Products Matter
A septic system is a living biological environment. Maintaining bacterial health is critical for effective wastewater processing.
For best results, use biodegradable, septic-safe household products and avoid:
-
- Bleaches
- Anti-bacterial cleaners
- Caustic drain cleaners
- Disinfectants
- Excessive detergents
- Solvent-based cleaners
