Which method must always be used for Wisconsin mound absorption fields?

In the context of Wisconsin mound soil absorption systems, the method of time dosing is important because it allows for the controlled application of effluent over a period, rather than all at once. This systematic approach helps to maintain a consistent moisture level in the soil, preventing over-saturation and promoting better treatment of wastewater.

Time dosing is crucial for optimizing the performance of the mound system, as it mitigates the risk of surface runoff and allows adequate time for the soil to absorb and treat the effluent effectively. This method also helps to reduce the impact on the environment by ensuring that the effluent is distributed evenly over the absorption field, which can enhance the overall effectiveness of the treatment process and extend the life of the system.

Other methods like manual dosing and gravity distribution may not provide the same level of control necessary for efficient performance, and continuous flow could lead to saturation and inefficiencies. Thus, time dosing stands out as the required practice for managing absorption fields effectively in Wisconsin's unique soil and environmental conditions.
