The solution came in the form of an innovative system from the Clean Green E luent Company, which has since proven its worth on their 93-hectare, 240-cow operation. " The farm receives between 2.5 to 3 metres of rain annually, making traditional e luent management systems problematic. We needed a system that didn't capture a lot of water. That's where the Clean Green E luent Company itted us well,” explains Wayne. Lindsay Lewis, founder and system designer of The Clean Green E luent Company, has developed a patented solution with the system's core feature its ability to apply e luent at very low rates - as little as 0.25mm per 24 hours. This approach, combined with a stormwater diversion system on Wayne and Tyler’s farm, ensured that large rainfall events don't overwhelm the e luent management process. The Langford farm's setup includes three storage tanks with a total capacity of about 100,000 litres, supplemented by a small Clean Green Effluent System Proves Its Worth on Golden Bay Dairy Farm concrete-lined weeping wall pond. This con iguration eliminates the need for large storage ponds, a key selling point for many farmers. One of the system's standout features is its fully automated operation. "It's a time saver with my busy role," Wayne says. "We use it di erently at di erent times of the year. When ground conditions are more risky, we take care of dispersing the e luent through the system manually. In summer, we use it as a fully automated system." The heart of the Clean Green E luent system is a unique patented concrete-lined weeping wall. According to Lindsay this component 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 e icient solids removal process has impressed Wayne. "I've been amazed that because the solids are captured in the pond, the e luent put on the farm is relatively clean," he says. "The cows graze down the e luent areas as they would with any other paddock. Whereas before, they'd leave a lot of the grass behind on areas we'd distributed e luent on.” The system is also a real time saver. "We have only had to empty out the solids from the pond once every three years and can utilize that on the farm, so the system has a neutral cost if not a bene icial cost to the farm." Lindsay explains that the low nutrient content of the liquid e luent allows for daily application to pastures. "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 utilized by the pasture as it is applied," he says. This contrasts with anaerobic e luent from traditional pond storage, which can take several weeks to become plant-acceptable, potentially leading to nutrient losses and metabolic issues in the pasture. For Wayne, the system's simplicity was a major selling point. "We did look around at a lot of other systems, which seemed to be quite mechanical, and I'm not mechanically minded," he admits. "This system is fairly simple, and there is not too much that can go wrong with it. It's really well designed." After a few years of use Wayne is unequivocal in his assessment: "It's lived up to all our expectations and more."
