A drinking water emergency well, also known as a street well , is a federal institution in Germany to ensure the public water supply of the population in large cities and metropolitan areas with sufficient drinking water in an emergency (reduction or total failure) .

overview

Since 1970, the federal government has maintained around 4800 drinking water emergency wells throughout Germany on the basis of the Water Safety Act, including around 900 of the around 2000 street wells in Berlin. A list of the tapping points reserved for the case of defense is contained in the Federal Emergency Well Directory. The WasSiG looks not only to ensure the supply of drinking water before, but involves the use as process water ( "the essential scope") and of fire-fighting water with one.

These “emergency wells” are “originally designed for a case of defense ”, but can also be used in any other dangerous situation. Drinking water emergency wells are independent of the public water network and receive their water from their own well or drawn springs . The water can be pumped manually or by an electric pump. In addition to these “federal wells”, other such “clumsy” fountains are operated by the State of Berlin as civil defense institutions. These public taps are complemented by a network of private wells, for example in companies. The latter are used by large companies to deliver water in the event of a fire.

In order to keep street wells running, they should be pumped with them regularly, as a malfunction can lead to failure due to various influences. Watering street trees or cooling down on hot summer days are suitable for such uses. It is forbidden to use it to wash cars, as is washing in public streets. The danger, however, lies in dirt and pollutants that could get from the vehicle into the ground and thus into the groundwater. Street wells for emergencies are at risk, for example, from vandalism or collision damage when parking motor vehicles , as well as from the drying up of the source power.
