When constructing a retention basin, what should be avoided during the work process?

When constructing a retention basin, it is crucial to avoid excessive compaction of surface soils. This is important because excessive compaction can lead to reduced infiltration rates, which diminishes the basin's ability to manage stormwater effectively. A retention basin relies on the ability of soil to absorb and filter water; when the soil is overly compacted, it becomes less permeable, leading to increased runoff rather than allowing for proper water absorption.

Furthermore, adequate soil porosity is essential for the biological processes that happen in the basin, including the natural filtration of pollutants. Therefore, while some level of compaction may be necessary for structural stability, it must be carefully controlled to ensure that the retention basin functions as intended in managing stormwater flow.
