Csapadékvízhálózat

Csapadékvízhálózat refers to the system designed to manage and convey rainwater and meltwater within an urban or developed area. This network typically includes a combination of surface features like ditches, swales, and permeable paving, as well as underground components such as pipes, culverts, and storm drains. The primary purpose of a csapadékvízhálózat is to prevent flooding by collecting excess water from impervious surfaces like roads, roofs, and parking lots, and directing it away from populated areas and infrastructure.

Effective design and maintenance of a csapadékvízhálózat are crucial for several reasons. Firstly, it protects buildings and infrastructure from water damage. Secondly, it helps to mitigate environmental pollution by preventing untreated runoff from directly entering natural water bodies. Runoff often carries pollutants such as oil, grease, litter, and sediment from the urban environment. While some modern systems incorporate treatment elements, the fundamental role remains water conveyance. The planning of these networks considers factors like topography, rainfall intensity, soil type, and the capacity of the receiving water bodies. Various strategies, from traditional piped systems to more sustainable urban drainage systems (SUDS) that emphasize green infrastructure and natural processes, are employed in the implementation of csapadékvízhálózat.
