Handy Hints and FAQ’s
What is Effluent?
Effluent is the liquid waste water that passes through your septic system
and requires a distribution system to ensure sustainable assimilation in the
soil. Although it is called "waste water" think of it as a valuable
resource you can re use.
Managing your Effluent
As your Effluent Management System (EMS) is installed in shallow trenches
care must be taken to prevent damage to pipe work below the ground. This means
the area must be designated a no stock site, e.g. pigs, cattle,
horses. To keep grass down sheep or goats can be grazed on site periodically
of time. Mowers and weedeaters can be used but no heavy vehicles can
be driven across the disposal field. Planting of disposal field with ground
cover or small shrubs is an advantage (although trees must not be planted on
or too close to pipe work below the
When electrical connection is carried out as part of Effluent Management Systems
Ltd installation contract, a high level alarm is fitted to the effluent pump.
This alarm will alert you to any pump problems. Contact service person if alarm
Caring for your Effluent Tank
- Use water conservatively (recommend water saver devices to be fitted
on all showers).
- Use biodegradable household cleaners and synthetic laundry powders
or liquids (i.e. petroleum based).
- Recommend you use body washes, shower gels etc, as these products
are synthetic based, instead of soap.
- Ensure you use water saver, sudsaver cycles on your dishwasher
and washing machine if fitted.
- Be aware of your effluent tank and disposal field locations.
- Be aware of high-level alarm light on effluent tank pump. if red
light is on this is a warning that something may be wrong with the pump.
06 879 8022 if this happens.
- For trouble free operation, regular servicing is required.
- Avoid using soap based washing powders.
- Do not install a wastemaster disposal unit.
- Do not dispose of nappies, sanitary napkins/panty shields or condoms
- When cleaning plumbing fixtures do not use strong bleaches, chlorine
compounds, antiseptics or disinfectants.
- Do not allow fat to be poured down the sink.
- Do not put petrol, oil, flammable/explosive substances or chemicals
from garage, e.g. pesticide, paint cleaners, photographic chemicals or trade
- Do not empty a spa or swimming pool into system.
- Do not direct roof or surface water to foul water drains or effluent
- Do not drive heavy vehicles over effluent tank or disposal field.
- Do not build over effluent tank.
To help reduce sludge building up in the effluent tank:
- Scrape all dishes to remove food material etc before washing.
- Keep all possible solids out of the system.
To help reduce the volume of effluent liquid required to soak in the field
- Install water saving devices.
- Take showers (moderate length of time) instead of baths.
- Only wash cloths when there is a full load / use dishwasher when there
is a full load.
- Try and avoid using the washing machine and dishwasher at the same time.
- Endeavour to space out water use as evenly as possible, so that the system
is not overloaded with a large volume of water at one time.
NB: Large volume discharges, e.g. spa baths, several loads of washing in a
row, several showers one after the other, may cause alarm light to come on
until the pump out cycle catches up. If alarm persists contact 06 879 8022
Clean effluent tank at about the 3-5 year period. This, however, is dependant
on the number of people your system caters for and the build up of sludge and
Tanks need to be pumped out when the scum layer (layer of crust on top) comes
down to within 100 mm of the bottom of the tee junction or filter at outlet,
or when the sludge (build up of material on bottom of tank) and scum have accumulated
to the extent that the scum and sludge has taken up 2/3rd of the volume of
the tanks first chamber.
Maintenance Service Contract
Effluent tanks need to be serviced regularly by a service technician who
will complete checks as per system requirement. This service ensures the
treatment and disposal system is maintained and operates efficiently and
