Pricing up di erent options when he was looking for a new system he says the Clean Green E luent Company option was the most a ordable and made a lot of sense in terms of how low maintenance it was. Thirty minutes a day spent moving a travelling irrigator option is just 30 minutes a week with his Clean Green E luent Company system. With no storage ponds required the fully automated system can apply e luent at 0.25mm (1/4mm) application depth per 24 hours. It doesn't take much time to maintain, has low running costs and can save up to 60% on fresh water conserving this precious resource for other important uses on farm. The system starts with a unique patented concrete lined weeping wall that, according to the Clean Green E luent Company, removes 35% more solids and nutrients from the e luent than any other weeping walls tested and is over 1000 times cleaner than a solids press. This iltered liquid is suitable for cleaning external yards and automated green washing of external yards via the system can reduce fresh water usage by 60% and wash time to nothing. Solids removal reduces NPK in liquid e luent to a level that allows the fully automated, low rate, low depth application system to safely apply e luent to land on a daily basis at a maximum rate of 0.75mm application depth. This removes the risk of nitrate leaching or ponding. As the solids dry in the weeping wall, the liquids separate and are distributed to pasture. The entire system stays odour free and aerobic and, as the NPK levels in the liquid are low, it can be utilised by the pasture immediately. As the nutrient loading within the liquid is greatly reduced, the pods only require movement on a fortnightly basis. Solids stored in the weeping wall are removed and applied to pasture as dry humus. This low rate low depth application allows e luent to be applied safely to land on a daily basis therefore reducing storage requirements to a minimum. Clean Green E luent Company system designer and company founder Lindsay Lewis says that because the liquid e luent is dispersed on a daily basis it keeps its aerobic form alive, which means that liquid is plant acceptable and can be utilised by the pasture as it is applied. Anaerobic e luent (pond stored) on the other hand can take several weeks to become aerobic and plant acceptable and this process time can cause excessive nutrient losses and metabolic issues in the pasture. Paul agrees that the Clean Green E luent Company system is a robust user-friendly process that guarantees full utilisation of all the farm’s nutrients while reducing workload and high running costs. He appreciated how the Clean Green E luent Company could design and install a fully automated, turnkey system along with providing an independent assessor to complete the consent application. “Lindsay is fantastic and really went the extra mile to ind a customised solution for the farm. We are very happy with the result.” A huge labour saver
