Downspout disconnection may be the simplest water quality friendly stormwater technique. It involves redirecting water from the stormwater system to individual yards by literally disconnecting the roof downspout and through a variety of means directing that water to nearby yard space. Here a short flexible extension and a splash block direct the water to a grassy area.

This house uses a long extension to provide distance from the house and direct the water to plants that need it. Downspout disconnection slows and reduces stormwater runoff from a site.

Two gutter lengths are used in this example to direct water from the whole front of the roof to the planting area. Downspout disconnection can reduce the need to water plants and thus save potable water.

This picture clearly shows the piping system that the disconnected downspout was disconnected from. Once the disconnection is complete, pipes like this should generally be capped.
