Domestic Wastewater Treatment Systems
EARTHSAFE WASTEWATER TREATMENT SYSTEMS
The Earthsafe Domestic Wastewater Treatment system is available in both concrete and
polymer models and are the result of over twenty years experience in the
wastewater Industry. They both use high quality components and all
internal chambers are built in polypropylene, which is extremely strong
and is impervious to corrosion, as are all internal fixings which are
marine grade 316 stainless steel. The electrical component is simple and
hard wired with overload protection, making it extremely reliable like
the rest of the system.

Listed below are the of various “EARTHSAFE” wastewater treatment systems
manufactured by Eco Water (Qld) Pty Ltd. Use the following descriptions
to select the system you require or contact us to discuss your
requirements. All Earthsafe systems have been fully tested and
accredited by the Queensland Government Authorities to treat up to 3 000
litres per day.
Type 1 - Earthsafe Polymer Twin Tank Models
The Earthsafe D10 Polymer treatment system is built inside two injection
moulded purpose built tanks. The system is light weight (360Kg) and can
be easily transported upon a ute or trailer to site where it can be
lifted into the excavation by the machine that digs it (no crane
needed). The total volume of treatment within the polymer systems is 6,
400 litres with an invert of 400mm standard. If a deeper invert is
required a 350mm polymer riser can be supplied with the systems.
Features and Benefits
- Multi-chamber system ensures five separate treatment stages including twoclarifiers
- Largest capacity injection moulded polymer tanks available … 3200 litres = More volume = Better treatment!
- Air pump, has a 3 year warranty and only uses 58 watts of power
- Standard irrigation pump only uses 250 watts of power at 9m head
- All metal fittings etc, inside tank, are 316-grade Stainless Steel.
- Government approved ~ Australian designed and manufactured.
- Simple rugged electrics – Eliminates fragile motherboard or PLC to fail.
- Lightweight – Polymer model can be installed by the digger doing the excavation.
- Can be transported on a single pallet on a flat deck utility or large trailer to site.
D10SF Secondary Standard
As Described above with a 9m Head Irrigation Pump suitable for above ground sprinklers
Water Discharge quality:
20mg / L BOD
30mg / L Suspended solids
100 / per 100ml (cfu) Thermotolerant count
D10SF H.H. Secondary High Head
AS above with a 30m Head Irrigation pump suitable for discharging to
areas further than 30 metres or to a higher level, or for belowground
pressure drippers.
Water Discharge Quality:
20mg / L BOD
30mg / L Suspended solids
100 / per 100ml (cfu) Thermotolerant count
D10 SF AS Advanced Secondary
This system is similar to the standard Earthsafe D10SF, however
incorporates additional features to produce a higher standard of
irrigation discharge. This is normally necessary in more environmentally
sensitive areas (near waterways, wetlands or with sensitive shallow
ground water etc) The higher discharge quality allows discharge within
10 metres of waterways and has lower environmental impact “Advanced
secondary” quality irrigation is sometimes required by Councils in these
circumstances.
This model D10 SF AS is supplied with an internal filtration unit.
Water Discharge Quality:
10mg / L BOD
10mg / L Suspended Solids
10/ per 100ml (cfu) Thermotolerant count
D10 SF AS / NR Advanced secondary with nutrient reduction
Again this system is similar to the advanced secondary model, with the
addition of an external filter pod and fitting kit. The fitting kit
includes six (x6) 15kg bags of “Nutrilok” filter aggregate. This is a
far superior filtration material than sand and also has the capability
of also removing heavy metals etc. This material removes a substantial
amount of both Nitrogen (N) and phosphorous (P) from discharged clean
water as well as some heavy metals. This model is particularly suited to
environmentally sensitive areas (especially marine environment). The
filter can be backwashed easily while being serviced and “Nutrilok” is
available from the system manufacturer if needed.
The water quality of irrigation from this system is less than or equal to;
10mg / L BOD
10mg / L Suspended Solids
10 / per 100ml (cfu) Thermotolerant count
10mg / L Nitrogen
5mg / L Phosphorous
Type 2 - Earthsafe Single Concrete Tank Models
The Earthsafe D10 Concrete models are built using the same quality
components as the polymer models, the only difference being the complete
system is encased inside one single tank that is 2.4m in diameter. The
system is delivered to site complete with the electrical box mounted on
the lid ready to go. They are simply installed in-ground and connected
to the household drain line and power supply. The system is then ready
to irrigate to an area approved by local council. The only thing to
consider with a concrete single tank system is that it must be delivered
and placed in the excavation by a crane truck (or crane) as it weighs
4.5 tonne. Total volume or treatment within the concrete system is 7,
000 Litres with a standard invert of 500mm. Risers available up to 900mm
on request.
D10SC Secondary Standard
As described above with a 9m head Irrigation pump suitable for above ground sprinklers.
Water Discharge quality:
20mg / L BOD
30mg / L Suspended solids
100 / per 100ml (cfu) Thermotolerant count
D10SC H.H. Secondary High Head
AS above with a 30m Head Irrigation pump suitable for discharging to
areas further than 30 metres or to a higher level , or for below ground
pressure drippers.
Water Discharge Quality:
20mg / L BOD
30mg / L Suspended solids
100 / per 100ml (cfu) Thermotolerant count .
D10 SC AS (Advanced Secondary)
This system is similar to the standard Earthsafe D10SC, however
incorporates additional features to produce a higher standard of
irrigation discharge. This is normally necessary in more environmentally

ground water etc) The higher discharge quality allows discharge within
