The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.
A dry well receives water from entry pipes at its top. It can be used as part of a stormwater drainage network, an agricultural well drainage system or on smaller scales such as collecting stormwater from building roofs. It is used in conjunction with pretreatment measures such as bioswales or sediment chambers to prevent groundwater contamination.
The drain is characterized by its long length and narrow width, the cross-section of the drain is a function of the maximum flow volume anticipated from the surrounding surface. Channels can range from 1 inch (2.5 cm) to 2 feet (61 cm) in width, while depths can reach up to 4 feet (120 cm).
Each of these plumbing fixtures has one or more water outlets and a drain. In some cases, the drain has a device that can be manipulated to block the drain to fill the basin of the fixture.
