By installing tile drainage, the water table is effectively lowered and plants can properly develop their roots. The lack of water saturation of soil permits oxygen to remain in the pores of the soil for use by roots. Drain tile prevents the roots from being under the water table during wet periods, which can stress the plants.
In building construction, weeps are typically found in a masonry veneer or cavity wall, just above the flashing. The cavity serves as a way to drain this water back out through the weep holes. The weep holes allow wind to create an air stream through the cavity. The stream removes evaporated water from the cavity to the outside.
A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
the design drain spacing (L) can be found from the equation in dependence of the drain depth (Dd) and drain radius (r). Drainage criteria One would not want the water table to be too shallow to avoid crop yield depression nor too deep to avoid drought conditions. This is a subject of drainage research.
An earth sheltered house in Switzerland (Peter Vetsch) An earth shelter, also called an earth house, earth-bermed house, earth-sheltered house, [1] earth-covered house, or underground house, is a structure (usually a house) with earth against the walls and/or on the roof, or that is entirely buried underground.
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

An eccentric cone has the top opening shifted off center all the way to one side of the manhole wall. This is to allow installing permanent ladder rungs on to the manhole wall. In designing eccentric cones, the loads need to be carefully calculated as one wall is vertical wall that is aligned to the chamber wall but the opposite wall is a slope ...
