How should the soil conditions be characterized for mound system construction?

For mound system construction, low moisture content in the soil is essential because it allows for proper filtration and absorption of effluent. Mound systems are designed to treat wastewater by allowing it to percolate through the soil, and if the soil is too saturated or has high moisture content, it can hinder the effluent from being adequately treated. In such conditions, the soil's ability to absorb water diminishes, leading to potential surface ponding, which can create odor problems, attract pests, and pose public health risks. Additionally, appropriate low moisture conditions promote the activity of beneficial microorganisms in the soil that are necessary for efficient anaerobic and aerobic treatment processes. Understanding these soil characteristics helps ensure that the mound system operates effectively and minimizes environmental impact.
