HOME OWNERS CARE GUIDE
• Household Cleaning Chemicals
Effects on Wastewater and Disposal System Receiving Environments
Use of many cleaning chemicals in facilities served by on-site disposal systems, can result in high
concentrations of the constituents in those cleaning agents being discharged into the receiving
soils. These chemicals and constituents can have a massive impact on the quality and condition of
the receiving soils over time.
Many of the chemicals can disrupt soil structure and decrease hydraulic conductivity while others
can act as bactericides, destroying the essential micro-organisms required to achieve the high level
of biodegradation in the treatment and disposal systems.
The following matters need to be considered when using cleaning agents in a domestic situation:
• Laundry powders are often extremely high in sodium which will destroy the salt balance in the
soils. Check the labels for low sodium and phosphorous contents.
• Wastewater flow from dishwashing machines can have an impact on wastewater treatment
systems, in terms of the strong cleaning chemicals used, so check labels for low sodium products
• Highly corrosive cleaners (such as toilet and drain cleaners) that have precautionary labels
warning users to minimise direct contact, are an indication that they can adversely affect the
wastewater treatment system. Up to 1 cup of bactericides such as bleach can be sufficient to
impact on all the microorganisms/bugs in a septic system.
