Humans were once a purely nomadic species, meaning they only stay in one place and leave when they have eaten up all the ready food or when a storm is headed for that area. Nature in case,granted just sufficient security from the harsh elements. The trees held the water and prevented sudden floods, providing ample time for the humans to relocate to a more comfortable place.
However, when the humans started to produce permanent settlements to live in, they were faced with a new issue. They could no longer run away from rainstorms since they couldn't leave their food source and protection behind. What's worse, the trees that once protected them from floodwater were cut down to provide space for houses and farms, leaving them vulnerable to sudden torrents of floodwater, killing people and destroying property.

Water pollution also became a major issue. Road surfaces contained oil and waste materials which are carried by storm water into nearby streams and rivers. These pollutants poison fish and other water animals, destroying possible food sources. Finally, rainstorm eats away the soil nearby the settlements, causing gigantic erosion. Sinkholes and landslides have killed countless people and buried entire communities.
To help sacrifice the negative effects of inordinate rain, humans advanced dissimilar kinds of management systems. Among the first water systems ever advanced were the aged Greek's water canals. These aged waterways were the ancestors of modern storm water systems protecting communities today.
These systems are also known as Best management Practices, or Storm Water Bmps. It can be designed to redirect rainstorm waters' safely away from a community, sacrifice its volume, or treat the water's quality before releasing it to nearby bodies of water. These are integrated with other systems, forming a single Bmp that performs all three functions.
