Domestic Wastewater Treatment
Our Systems
The following is a list of various "EARTHSAFE" Wastewater Treatment Systems manufactured by Eco Water Holdings Pty Ltd
Select the system you require or ring us and discuss your requirements. Some Council's require more advanced systems for installation in environmentally sensitive areas and we can easily supply those.
All Earthsafe systems have been fully tested and accredited by the Queensland Government Authorities and some have been accredited by the NSW Health Dept.
"Primary" treated water is that produced by a septic tank system and still contains 10 million bacteria per 100 millilitres of liquid.
"Secondary" treated water is produced by many treatment systems and produces irrigation with less than or equal to;
| 20g / m3 | BOD |
| 30g / m3 | Suspended Solids |
| 100g / per 100ml | (cfu) Thermotolerant count |
"Advanced Secondary" treated water is produced by adding extra equipment into the secondary system and produces irrigation with less than or equal to;
| 10g / m3 | BOD |
| 10g / m3 | Suspended Solids |
| 10g / per 100ml | (cfu) Thermotolerant count |
"Advanced Secondary system with Nutrient reduction"
This type of system must have a tested and accredited method of significantly reducing the nutrients of Nitrogen (N) and Phosphorous (P)
The Earthsafe AS/NR system incorporates a special nutrient reduction aggregate mix in its filtration system and can "lock up" a substantial amount of nutrient element as well as some heavy metals.
The water quality of irrigation from this system is less than or equal to;
| 10g / m3 | BOD |
| 10g / m3 | Suspended Solids |
| 10g / per 100ml | (cfu) Thermotolerant count |
| 10g / m3 | Nitrogen |
| 5g / m3 | Phosphorous |
D10SF standard "Secondary domestic system treatment"
Supplied in 2 x3200L polymer tanks with 14 metre head irrigation pump 400mm invert, chlorine disinfection.
This system is also available with a high head (36m) irrigation pump suitable for discharging irrigation to areas further than 30 metres or to a higher level , or for below ground pressure drippers.
This standard system consists of 2 x 2300L volume polymer tanks (one inside the other) weight 360 kg on a pallet. Can be transported on a Ute or trailer with 1800mm x 1800mm flat space. Tie down with 2 x ratchet straps for transport. Needs an excavator or forklift to unload and separate the 2 tanks.
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 as well as an external filter pod and fitting kit. The fitting kit includes four (x4) 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. The filter can be backwashed easily while being serviced and "Nutrilok" is available from the system manufacturer if needed.
D10 SF AS / NR (Advanced secondary with nutrient reduction)
Again this system is similar to the advanced secondary model, however incorporates a special nutrient reduction mix in both internal and external system filters. 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 environments).
