Effluent system made simple

At Mooka Flats, Brad runs a 950-cow dairy operation. He needed an effluent system that would take the day-to-day pressure off his staff while providing a more reliable and sustainable solution. The existing clip tank system was continually filling with sand and solids, with no way of separating these before storage, which caused ongoing maintenance issues.

Project

After carefully considering the challenges of the high water table on this peat farm, we designed and installed a 25m x 10m double stone tray system. This setup provides effective separation of sand and solids, reducing blockages and ensuring a smoother, lower-maintenance effluent process.

The stone trap, effluent flows into a 190m³ Williams Moopoo sump, which serves as the main pumping point via gravity. A Yardmaster 3380 progressive cavity pump was installed, giving the flexibility to draw directly from the Moopoo sump or, through a simple changeover with butterfly valves, from the bottom of the existing clip tank. This design allows for safe and efficient emptying of the clip tank without additional handling or equipment.

Brad’s farm already had a two-line, 90mm mainline system. However, with the upgraded flow rate of 33m³ per hour, the 90mm line at the back of the farm was no longer adequate, causing pressure issues. To resolve this, we added 150 metres of new pipework and converted the layout into a ring main system with all new hydrants, dramatically improving efficiency and reliability across the farm.

To handle the longer paddocks (up to 600m in length), we installed a hard hose reel with 350m of 90mm pipe. This system can be connected from the middle of each paddock, making effluent application simple, even, and effective.

For consistent mixing and application, we also installed a Moopoo 4kW stirrer in the sump. This ensures the effluent is properly agitated before being pumped, providing a uniform nutrient spread to pasture and reducing blockages.

What we did

This farm required a dependable solids separation solution. The Williams 25x10 Double Stone Trap was installed to effectively separate solids before the effluent enters the Williams 190-cube effluent sump. From there, irrigation is carried out using a Yardmaster 33/80 Progressive Cavity Effluent Pump, with the Williams MooPoo Stirrer providing additional solids breakdown and mixing for improved efficiency. When irrigation to pasture isn’t possible, excess effluent is seamlessly transferred to the existing Kliptank for storage, ensuring smooth operation in all conditions. To help with irrigation, the mainline system was upgraded to accommodate an Irriland 90/400 Compakta Irrigator.
