infiltrasjonsbasseng

Infiltrasjonsbasseng, also known as infiltration basins or recharge basins, are shallow, engineered ponds designed to allow treated wastewater or stormwater to seep into the ground. This process, called infiltration, helps to replenish groundwater aquifers. The water is typically held in the basin for a period, allowing natural processes like filtration and biological breakdown of pollutants to occur before it percolates into the soil.

These systems are often used as a component of wastewater treatment and stormwater management. For treated wastewater, infiltration basins can provide a final polishing step, removing remaining nutrients and pathogens. In stormwater management, they are used to reduce runoff volume, prevent flooding, and improve the quality of water entering surface water bodies. The design of an infiltration basin considers factors such as soil type, depth to groundwater, and the volume of water to be infiltrated. Vegetation is often planted within and around the basins to enhance infiltration rates and provide aesthetic benefits. Proper maintenance is crucial to ensure the long-term effectiveness of infiltration basins, as clogged pores or accumulated sediment can reduce their capacity.
