Concrete has been considered a good building material, but can be brittle over time and needs to be placed on solid ground. Plastic above ground tanks have a thin plastic liner and often feature a wall that is only two and half metres high, which does not offer the volume needed for larger operations. If there is high rainfall, there is an option to put a cover on the above ground tank to reduce the amount of rainwater the tank catches, but generally when above ground storage is required the recommended option is a flexible bladder effluent tank.
It’s important to assess the water table height, yearly rainfall and if your region gets earthquakes before considering which type of effluent storage system is right for your farm operations.
With an above ground tank, you cannot reach over the wall of the tank. There either has to be a pedestal beside the tank, with a mounted Nevada 7m Electric pond stirrer or a hydraulic tractor mounted stirrer. Nevada has developed an over-wall stirrer that is similar, but it is mounted on a post that is controlled from the ground. It is an efficient way of reaching over into the tank to mix the effluent thoroughly.
