How to keep your system working well  

Maintain your system regularly 

• Make sure your system can be easily accessed
• Maintain the system regularly. Keep all maintenance record- your council can request to see them 
• Use licensed plumbers to check if your system needs cleaning and unblocking
• Desludge the system every three to five years. How often depends on how much the system is used
• Maintain the disinfection chamber. This chamber uses chlorine to disinfect the treated water. Chlorine tablets must be fitted to the dispenser in the right way. If fitted with UV disinfection, UV light tubes must be cleaned regularly
• Have an accredited servicing agent install an alarm to warn you of breakdowns
• Don’t drive vehicles over any part of the system
• Don’t allow stormwater to discharge into the onsite system or over the disposal/drain field
• Don’t cover the tank or drain field
• Don’t place non-biodegradable items or rubbish into the system. Bacteria and other organisms can't break down these items or rubbish
• Follow any local council maintenance requirements.

Reduce sludge build up in the tank

• Scrape all dishes to remove fats and grease before washing
• Don't put solids in the system
• Don't use a food waste disposal unit unless your system can carry the extra load
• Don't put hygiene products in the system. For example, sanitary napkins and tissues.

Keep bacteria working well

Not all bacteria are harmful. Some of the bacteria in your onsite wastewater management system converts your waste to liquid and gas.

• Use biodegradable soaps and detergents that are low in phosphate. Phosphates feed algae that pollute waterways
• In dispersive soil areas, use detergents that are low in sodium
• Use the right amount of detergents
• Don't put chemicals or paint down your drains.

Avoid powerful chemicals

• Powerful bleaches, whiteners, nappy soakers, spot removers or disinfectants can impact how well your system works. Try to avoid using them.

Reduce the amount of wastewater you produce

• Install water saving fittings
• Take showers instead of baths
• Wash only full loads of clothes.

Avoid overloading your system 

• Space out your water use
• Don't do all your washing in one day
• Don't run your dishwasher and washing machine at the same time.
