Dry well

Receiving waters and receiving waters are terms from the water. They belong in the extensive complex of drainage. Literally, they are understood to be " before the flood ", ie as " measures of impending flood ." In the scientific sense include receiving water and outfall for the terminology of hydraulic engineering.

Excess water

Excessly are waters which are mainly due to volume, but also as brackish or waste waters become a threat to the land use. Receiving water is to collect excess water for the purpose of avoiding

• Natural flooding, eg due to high sea tide, by groundwater, precipitation and melt, and
• About artificial flood as a result of private, commercial or industrial waste water.

Receiving water is called the collector or collection for the disposal of excess water. Collectors are usually grooves or pipes. The excess, mostly via seepage, open rivulets, streams or artificial inflows emerging water is collected in the receiving water and drained by natural gravity, to the main receiving water immediately picks up the drain, or go to the regulated outflow through a sewer or a lock.

Main outfall

Main receiving water is the major effluent, such as the river which receives on its way the water of the receiving water and allowed to run down to the sea and so it returns to the natural cycle.

In addition to receiving waters

In addition to receiving waters is called the remedy that receives the amount of water that exceeds the power capacity of the receiving water. This is a branch of the receiving water, which feeds back either via a detour elsewhere in the extended outfall there or has its own direct or regulated drain into the main outfall. If the natural drainage on the receiving water is not possible, perhaps because he does not own a drain, or maybe because the main receiving water body, for example in low-lying areas is higher than the receiving water, so apply artificial dissipation via a pumping station ( pump system ). In the case of the outfall drains water to the pumping station, which is equipped with a correspondingly large forebay ( a collector ). There, the pump operation is controlled by a level control.
