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

  1. Multi-chamber system ensures five separate treatment stages including twoclarifiers
  2. Largest capacity injection moulded polymer tanks available … 3200 litres =  More volume = Better treatment!
  3. Air pump, has a 3 year warranty and only uses 58 watts of power
  4. Standard irrigation pump only uses 250 watts of power at 9m head
  5. All metal fittings etc, inside tank, are 316-grade Stainless Steel.
  6. Government approved ~ Australian designed and manufactured.
  7. Simple rugged electrics –  Eliminates fragile motherboard or PLC to fail.
  8. Lightweight – Polymer model can be installed by the digger doing the excavation.
  9. 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 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 SC 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 SC 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.

10 mg/ L Suspended Solids                                
10 / per 100ml (cfu) Thermotolerant count
10mg / L Nitrogen
