Are Koh products compatible with septic tanks?Updated 12 days ago

Eleven Koh products are septic and greywater compatible when used as directed, and each one is named here rather than covered by a blanket statement: Universal Cleaner, Bathroom and Shower Cleaner, Kitchen Grease and Oil Cleaner, Sensitive Laundry Liquid, Stain Remover, Dishwashing Liquid, Loo Cleaner Tabs, Dishwashing Tablets, Laundry Detergent Sheets, Sensitive Hand Wash and Sensitive Body Wash. None of the eleven contains chlorine bleach or quaternary ammonium compounds (quats), which are the ingredients most likely to disrupt septic bacteria. Always use only as directed on the label, never pour undiluted product directly into septic or greywater systems, and avoid excessive use beyond normal cleaning applications.

Each of the eleven Koh products listed above is septic and greywater compatible when used as directed. Three things to keep in mind for every one of them: use only as directed following the label dosage, do not pour undiluted product directly into septic or greywater systems, and avoid excessive use beyond normal cleaning applications.

All eleven Koh products named above are compatible with greywater systems and AWTS when used as directed. Suitability for greywater reuse also depends on soil type, the plants being irrigated, and local council regulations. Those factors vary by location and are worth checking with your local council or greywater system supplier before reusing wash water on the garden.

Seven Koh products carry GECA (Good Environmental Choice Australia) certification: Universal Cleaner, Bathroom and Shower Cleaner, Kitchen Grease and Oil Cleaner, Sensitive Laundry Liquid, Stain Remover, Dishwashing Liquid, and Loo Cleaner Tabs. GECA is Australia's independent ecolabelling body, and GECA certified formulations meet verified standards for environmental and human health impacts across their full lifecycle. Certification applies to the formulation, not to cleaning tools.
