Sadeveevõrgu

Sadeveevõrgu, a term originating from Estonian, translates to "rainwater drainage system" or "stormwater system" in English. It refers to the network of infrastructure designed to collect, convey, and manage surface water runoff from rain, snowmelt, and other precipitation. This system is crucial for urban and developed areas to prevent flooding, protect property, and maintain water quality.

The components of a sadeveevõrgu typically include gutters, downspouts, catch basins, storm drains, culverts, underground pipes, and sometimes retention or detention ponds. Gutters and downspouts collect water from rooftops, channeling it away from building foundations. Catch basins are grates at street level that capture surface runoff and direct it into the underground pipe network. These pipes then transport the water, often to larger bodies of water like rivers, lakes, or the sea, or to treatment facilities if necessary.

Effective functioning of a sadeveevõrgu is vital for public safety and environmental health. Blockages caused by debris, such as leaves, litter, or sediment, can lead to localized flooding and damage. Furthermore, stormwater runoff can carry pollutants from streets and other surfaces into receiving waters, impacting aquatic ecosystems. Therefore, regular maintenance and proper design of these systems are essential. In some contexts, the term might also encompass the planning and management strategies related to urban water runoff.
