  • Effluent Pond Stirring

      Effluent Pond Stirring

    SJ Allen Ltd has an effluent pond stirrer which will turn that crusted and grass-encased effluent pond into slurry which their vacuum trucks can then spread onto paddocks.

    Their effluent pond stirrer can be driven by any tractor with 40+ hp capability via a three point linkage PTO system.

    Whether you pump from a pond or a tank it is essential that you stir with an SJ Allen Pond Stirrer before and during pumping to ensure that solids containing high levels of nutrient value like nitrogen and potassium are pumped out rather than stagnating at the bottom of the pond/tank producing sludge.

    Stirring puts the effluent into suspense and allows for an even spread of nutrients onto the pasture when pumping. Unmixed effluent can cause some paddocks to be overloaded with black rich effluent, with others only receiving an application of dirty water. Stirring ensures reusable fertilising commodities while maintaining the most holding capacity available.

    SJ Allen has effective and reputable stirring options available

  • Saucers


    Whatever a dairy farmer decides to do, it is vital they gets an SJ Allen effluent system expert in to discuss your options.

    Concerning Saucers, no longer will the local builder or contractor build because of strict compliance standards. Effluent management in general such as plants pumps, ponds, system layouts, electricity and gravity, all need to be taken into very serious account when designing or redesigning a modern effluent system. Gets it wrong it can really cost you. Not to mention visits from compliance officers.

    SJ Allen Saucer solutions are designed to circulate the effluent as it fills and empties so nothing builds up on the surface or bottom. Because the effluent movement is maintained, it keeps solids suspended as you pump out the liquid.

  • Wedges


    The sand traps/slurry Wedge is an essential component of an effluent management system. The trap allows stones and other solids to settle prior to entering the effluent tank or pond. This prevents blockages and damage to pumps and helps prevent sludge buildup, reducing cleaning requirements.

    SJ Allen provides reliable Wedge servicing and instalation options.

  • Underpasses


    SJ Allen cleans stock underpasses for easier stock movement and improve overall stock health.


  • Farm Waste

      Farm Waste


    SJ Allen specialises in Farm waste solutions, From farm effluent sumps and dairy pond recycling to waste oil, septic tank, holding tank, processing and storage tank waste recycling. We can take your waste away or turn it into liquid fertilizer to spread on your land.

    Effluent disposal is a valuable fertilizer and as this resource has already been paid for in your feed budget, it is wise to manage effluent in the most cost effective manner possible. SJ Allen can help. We can keep your wedge clean and well maintained so the slurry is more easily spread on paddocks and more readily absorbed into the root system. This means less withholding time for stock rotations.

    If paddocks become too wet or too scarce for effluent spreading, SJ Allen can also dispose of this waste off site.
