What issue is considered concerning maintenance of filter practices?

The accumulation of sediment deposits is a significant concern in the maintenance of filter practices. Over time, filter media can become clogged with sediment, reducing the effectiveness of these practices in managing stormwater runoff. If not regularly maintained and cleared of excess sediment, the filters cannot function properly, leading to potential overflow, reduced infiltration, and an inability to remove pollutants from the water. This can ultimately compromise the intended purpose of the filter system, which is to improve water quality and manage erosion risks.

While changes in soil composition, increased water pressure, and adaptation to vegetation growth can influence the performance of a filter practice, the immediate and most tangible concern related to maintenance is the accumulation of sediments. Regular maintenance is needed to ensure that sediment build-up does not hinder the function of the system and that it continues to effectively filter out pollutants from stormwater.
