csapadékvízlefolyó

Csapadékvízlefolyó, which translates to stormwater drain or surface water drain in English, refers to the system designed to collect and manage rainwater runoff from impervious surfaces. These surfaces include roads, rooftops, parking lots, and other areas where water cannot easily infiltrate the ground. The primary purpose of a csapadékvízlefolyó system is to prevent flooding and water damage by channeling excess water away from populated areas and infrastructure.

The design of these systems can vary widely depending on the scale and location. In urban environments, they typically consist of a network of gutters, downspouts, storm drains, underground pipes, and sometimes open channels or swales. Gutters and downspouts collect water from buildings, directing it towards street-level inlets. These inlets, often visible as grated openings in sidewalks or roads, lead into the underground piping network. This network transports the water, often through gravity, to a designated discharge point.

Discharge points can include rivers, lakes, oceans, or specialized retention or detention ponds. Retention ponds are designed to hold water permanently, allowing for natural evaporation and filtration, while detention ponds temporarily store excess water and release it at a controlled rate to reduce downstream flooding. In some cases, stormwater may also be directed to wastewater treatment plants, though this is less common as it significantly increases the treatment load. Proper maintenance of csapadékvízlefolyó systems is crucial to ensure their effectiveness and prevent blockages caused by debris, litter, or sediment.
