Normal Functioning
1. Air valves allow flow of air to diffusers; adjust valve to regulate air flow
2. All air valves are adjustable and are to be regulated as per visual inspection, to allow
adjustment of air flow to diffusers, sludge return & scum skimmer
3. Air bubbles & water flow in sludge return and scum skimmer indicate normal function
4. Visual inspection of air flow in aeration chamber indicates normal function of air blower
5. Engage pump float to check irrigation pump is operating normally
6. To check low air alarm, turn off blower to engage alarm, wait 2 minutes for activation.
Do not remove air blower pressure switch tube. Visual alarm on control box on tank
and alarm panel inside house
7. To check high water alarm, raise float on high water tube. Check if high water alarm is
activated
Servicing
1. Servicing to be done quarterly, as per contract with customer
2. Prior to service make any phone calls as required by occupants as detailed in run sheet,
to ensure access to property and dogs restrained where necessary. Address any other
notes listed on run sheet

4. Close all gates, etc. when entering and leaving the property
5. A Service Report Form must be completed for each service in triplicate – owner, Council
and file copy; fill in customer details using run sheet on Service Form
Maintenance Service
1. Remove manhole covers
2. Prior to putting on gloves, use dip to remove water sample from pump chamber
3. Take chlorine residual reading
4. Use dip to remove water sample from settling chamber
5. Take PH reading
6. Put on gloves
7. Use turbidity tube and dip to take water sample from aerobic chamber two and check
clarity and odour of water
8. Use turbidity tube and dip to take water sample from disinfection chamber and check
clarity and odour of water
9. Use sludge stick to clear any build up to inlet of primary tank if required
10. Take sludge build up reading in second primary chamber through inspection opening
11. Take sludge reading in aerobic chamber & settling chambers
12. Record readings from second primary tank and settling chamber
13. If there is a build up in settling chamber increase return flow slightly & stir base of
chamber
14. Turn sludge return tap in pump chamber on slowly for approximately 10 seconds or until
return water clears; then close tap
15. Adjust scum return if required and air lines using ball taps
16. Replenish chlorine and note quantity

17. Record chlorine residual & PH readings
18. Adjust chlorine adjustment cap if required to raise or lower residual readings
19. Clean irrigation filter if applicable
20. Engage irrigation pump to inspect irrigation line and inform customer if repairs are
required
21. Check land application area for conformity to NSW Health and local council
requirements

23. Secure system lids and covers
24. Complete service form
25. Specify if wrong products are being used. Suggest alternative products to use
26. Leave copy of service report for owner unless run sheet advises otherwise
Low Water Clarity
1. Generally caused by too much or incorrect laundry detergent being used. Also very
soapy water indicates too much laundry detergent is being used per wash
2. If water clarity is low and smelling this may be from fabric softeners
3. If water is brown and frothy in aerobic chambers, this is generally caused by antibiotics
but after settling chambers, water clarity is generally clear. Nothing can be done to
improve this until use of antibiotics is ceased
4. If water is stained in colour a reddish or brown this could be caused by hair dyes and will
not necessarily affect the performance of the system. Chlorine residual level may need
to be increased
5. Disinfectants and antiseptics may decrease water clarity. This is indicated by dead
bacteria scum build up in settling chamber. The scum return will not remove this during
normal operation as the scum forms on the outer perimeters first. To remove this use
gauze scoop and bucket and return to primary tank. If there is too much scum build up
use sludge pump. This will need to be rectified with the owner as soon as possible.
Discuss product usage with owner. If the resident is not at home advise office. These
products damage system by lowering bio mass which will increase BOD and SS
System Smelling
1. Odour can be caused by wrong product usage. Check products with owner
2. If system has been unused for a period of time but still running, e.g. occupants on
holiday, system may smell if over used on return for first 1 to 2 days of use
3. Blower failure will cause odour at sprinkler head, indicated by alarm. After repairs to
blower, odour will dissipate within 12 to 48 hours
4. Irrigation water in pump chamber smelling but not aeration chamber smelling is due to
build up of sludge in pump/disinfection chamber. Remove with pump

High Water Levels
1. Check that high water alarm float is operational. Use spare float to test
Low Air Pressure in System
1. With no alarm activated can be caused by faulty valves in air blower
2. Replace chamber block kit or pistons in blower if necessary
Low Air Alarm
1. Usually diaphragm broken in air blower or worn piston in Nitto air blower. Replace
chamber block kit or piston
High Water Alarm
1. Irrigation blockage
2. Stuck float control
3. Failed pump
Desludge o Septic Chamber
1. Sludge build up is checked at each service
2. When levels rise to between 80cm and 100cm a full desludge of the primary tank is
required or as required by governing bodies
3. Sludge build up depends upon the number of people using the system and product
usage. Time varies between 3 and 10 years
4. Note on comment section on service form when a full desludge is required
