The benefits of using Clean Green on your farm.

Key Features

Parallel Timber weeping wall separates liquids from the retained solids. The bulk of the NPK is captured in this organic humus.

Distribution system allows controlled application to land at low rate low depth application rates of 0.25mm, thereby eliminating nitrate leaching, ponding or overland run off.

Due to the Low Rate Low Depth distribution system, effluent can be dispersed on a daily basis.

All nutrients stay in the root base.

Minimal storage is required and can be achieved with as little as 2x 30000 litre water tanks.

Tank storage eliminates rain water catchment.

Environmental Benefits

Reduction is Fresh Water Usage
Industry standards are 50-70 litres per cow per day for shed and yard wash. Farms operating the Clean Green Systems have reported an average shed wash use of 15-20 litres per cow per day. This is achieved via the use of the greenwash system to wash external yarding. This reduced water usage is confirmed by reports from regional councils, and water bore log reports.

Reduction in Effluent to be Discharged
Traditional “mega pond” storage facilities require a large foot print whereby rainwater can cause a substantial amount of liquid added to the pond. Once rainwater enters an effluent storage pond, this liquid is then contaminated and becomes effluent to be dispersed to land. By using sealed tanks as effluent storage, and minimising the footprint of the Weeping Wall, the Clean Green System attracts far less rainwater, thereby substantially reducing the amount of “effluent” to be dispersed to land.

Reduction in Leaching
By applying effluent to land via a controlled system at a very low application rate, the system ensures that all the nitrates, phosphates etc in the effluent are able to be taken up by the plant rather than leaching into groundwater. By applying effluent at rates less than pasture uptake, it means that the plant can safely digest all the NPK being irrigated to pasture, even in periods when soil moisture is high.

Controlled Nitrate Loading
Industry best practice require a yearly maximum of 150kg / ha of nitrogen from effluent. This can be a difficult figure to monitor and control. The Clean Green System is designed and installed to a strict adherence to nitrogen loading levels within the dispersal area, in conjunction with a farm Nutrient Management Plan. This ensure the best use of fertiliser within the dispersal area, and also prevents over-application and runoff.
As Clean Green continually monitor and test liquid irrigation levels, we are able to accurately manage nitrogen loading with Farmers.
Simple liquid and volume tests have ensured this system can distribute all the effluent liquid in an area of 2ha/100 cows and be fully compliant.
This is achievable due to the nutrient retention in the patented weeping wall.

Reduction in Runoff
The system irrigates to controlled paddocks, a suitable distance from exposed waterways and property boundaries. This ensures there is no risk of contamination to waterways, or run off to other areas of the farm as this can occur with the use of travelling irrigators.

Pond Leakage
The Clean Green weeping wall is encased in a fully engineered concrete sludge bed. This ensures that there is no leakage from the pond to groundwater, or any other leakage/overflow to surrounding areas. Similarly the storage tanks are sealed plastic, and cannot leak effluent.

Reduction in Odour / Offensive Discharge
As the Clean Green System quickly processes effluent from the shed to the paddock, the effluent remains aerobic, meaning there is virtually no offensive odour produced either from the storage facility or the dispersal system. Emissions are reduced as anaerobic (dead ) effluent odours are normally emissions.
