Urban development plan Supply & Disposal 1999

Explanations to the maps

General remarks

The maps give a general idea of the main urban networks for the individual kinds of supply and disposal, the cross linking of the factories, facilities and stations, as well as the integration of Berlin into supra-regional interconnections. In co-ordination with the utility companies the maps were drawn up to represent sites relevant for urban planning, showing the main networks, supply areas and catchment areas etc. The maps themselves are presented in the 1: 50.000 scale.

The locations and areas are shown in block-sharp and boundary-sharp manner. According to the purpose of the urban development planning, the mains and pipes are assigned as exactly as possible to roads, blocks and facility locations. But saying that the maps are not accurate enough to derive a precise position.

The survey maps and partial maps of the UDP supply and disposal do not contain any information about pipe cross-sections and the connection capabilities of plots of lands (allotments), areas and sub-areas, onto the networks and facilities of the technical infrastructure. The respective utility companies are responsible for and have to be consulted over content related issues pertaining to supply of resources and waste disposal.

The representation of the topography for the Brandenburg surrounding area of Berlin is limited to waters, lakes, railway lines, main roads and motorways. Built up areas including rural communities, districts and the municipality boundaries are represented in a simplified way.

This is to help orientation and general localisation of technical infrastructure plants. In contrast with the printed versions, the abundance of optical information on the maps of Internet versions leads to a partial restriction of the rapid intuitive grasp of the information.

In order to counteract this tendency, suitable display areas are defined according to the supply type. The maps are darkened outside the boundaries of the display areas with translucent coverings. The display areas shown can be town districts, trade centres or residential areas etc. The type is indicated in the key at the edge of the map.

Map water supply

The map shows the locations of the protected areas, main pipelines, water catchment and distribution areas important for the urban development of Berlin.

The Berlin Water Companies with 12 waterworks ensure the drinking water supply of the city as well as some of the boundary municipalities. This currently equates to approx. 240 Mio m³ of water provided annually.

All of the big waterworks are located in the Warsaw-Berlin urstromtal or in the lowlands of the Havel river. They produce exclusively groundwater, mainly bank filtrate. For the stabilization of the groundwater formation in the waterworks of Jungfernheide, Spandau, Stolpe and Tegel surface water is seeped in groundwater enrichment plants.

To protect the groundwater from all kinds of contaminants "water protection areas" are allotted for all waterworks. Any water endangering use is prohibited in the catchment area of the wells (water protection zone type I), with corresponding restrictions in the narrower and in the wider protection areas (water protection zone type II or III).

The entire settlement area of the city is connected with the water supply by a water pipeline network of 7.700 km in length. Water pipelines run along almost the entire road system. The map shows the main pipelines with diameters of 400 to 1.400 mm as well as the supply pipes with a smaller diameter(>150 mm), which are so essential for the suburbs.

The main pipelines (800 mm pipe diameter) from the waterworks to the supply areas are highlighted on the map. They fulfil predominantly a transport function. The drinking water for the entire eastern city and for the large residential areas in Marzahn, Hohenschönhausen and Hellersdorf is pumped on the so called water routes from the waterworks at Friedrichshagen to the pump stations Lichtenberg and Lindenberg in several parallel running main pipes. Sufficient high water pressure is guaranteed through the co-operation of the 4 big intermediate pump stations at Lichtenberg, Lindenberg, Columbiadamm and Marienfelde, as well as two additional pump stations at Kleistpark and Köpenick.
