A dry well or drywell is an underground structure that disposes of unwanted water, most commonly surface runoff and stormwater, in some cases greywater or water used in a groundwater heat pump. It is a gravity-fed , vertical underground system that can capture surface water from impervious surfaces , then store and gradually infiltrate the ...
Downspouts (or rain chains) can also channel H2O into rain barrels. Not only do the barrels help prevent water from seeping into the foundation, but they also have the added bonus of allowing you ...

They may be placed into excavated postholes , [ 2 ] driven into the ground, or on sills which are set on the ground without a foundation.

A small "underground home" built in the style of Oehler, as only a simple, non-waterproofed hole in ground with simple planks and a plastic sheet to a wall, despite using free labour (ignoring the opportunity costs of not having time to go to work) and recycled materials, e.g. windows and planks for the wall, is estimated to be 30% cheaper to ...

Downspouts are usually vertical and usually extend down to ground level , although may be routed at an angle to avoid architectural features and may discharge onto an intermediate roof.
