The ___MASK24___ ___MASK54___ ___MASK51___ is a landlocked federal state ___MASK54___ Germany , bordering the federal states ___MASK54___ Brandenburg , ___MASK51___ Anhalt , Thuringia , and ___MASK27___ , as well as the countries ___MASK54___ Poland ( Lower Silesian and Lubusz Voivodeships ) and the Czech Republic ( Karlovy Vary , Liberec and Ústí nad Labem Regions ). Its capital is Dresden , and its largest city is Leipzig . The Polsterberg Pumphouse ( German : Polsterberger Hubhaus ) is a pumping station above the Dyke Ditch in the Upper ___MASK12___ in central Germany which is used today as a ___MASK76___ restaurant . As part ___MASK54___ the Upper ___MASK12___ Water Regale it was built in the 18th century and was used to lift the water needed in Clausthal for the mining industry from the Dyke Ditch ( Dammgraben ) to the level ___MASK54___ the highest pond , the Hirschler Pond . Aside from this water hoist , the Dyke Ditch supplied , and still supplies , water over ditches and tunnels to the Hausherzberg Ponds and the Lower Peacock Pond ( Unterer Pfauenteich ) ( see also Middle Peacock Pond ) . The problem was however , that , as it happened , the most productive silver mines in the Upper ___MASK12___ mining region , the Caroline Pit and the Dorothea Pit , were high up in the mountains and could only be supplied with water power from the Hirschler Pond . The motive force for the wooden piston pumps was won in the Polster valley below by two water wheels . The headrace for these water wheels was brought via the Heller Valley Ditch ( Hellertal Graben ) from the Heller valley and from the Fortune Pond over its Bottom Ditch ( Grundgraben ) , but frictional losses and poor efficiencies meant that a considerable amount ___MASK54___ headrace water was required in order to lift just a few litres ___MASK54___ water from the Dyke Ditch . These wheels transferred their output power over 260 and 560 m long flat rods made ___MASK54___ wood to the pumping station on the Polsterberg hill . In the pumping station the water from the Dyke Ditch was pumped 8 m higher and fed into drinking troughs from which it was then further transported via the Hutthal Ditch and Huttaler Widerwaage to the Hirschler Pond , or via the Jägersbleek Tunnel and Ditch . The Polsterberg Pumphouse also acted as living accommodation for the master pumper and the ditch keepers , as well as a bar ( Schankstube ) . At the beginning ___MASK54___ the 20th century the wooden structures were replaced by electrically - drive pumps ; the original can still be seen in the pumphouse by the ditch . Today the building is listed . It is purely run as a restaurant and is a popular destination for walkers from Altenau and Clausthal - Zellerfeld . Like the nearby Sperberhai Dam House it lies on the ___MASK12___ High Road , the B 242 . See also : Polster Valley Wheel House Upper ___MASK12___ Water Regale The formerly free mining town (" Bergstadt ") ___MASK54___ Lautenthal in Germany is a state - recognised , climatic spa with around 2 , 000 inhabitants that has been part ___MASK54___ the borough ___MASK54___ Langelsheim since 1972 . The Sperberhai Dyke is in fact an aqueduct which forms part ___MASK54___ the Upper Harz Water Regale network ___MASK54___ reservoirs , ditches , dams and tunnels in the Harz mountains ___MASK54___ central Germany . It carries the water ___MASK54___ the Dyke Ditch over the depression ___MASK54___ the Sperberhai to the Clausthal plateau . ___MASK85___ is a German state (" Bundesland ") situated in northwestern ___MASK30___ and is second in area , with , and fourth in population ( 8 million ) among the sixteen " Länder " ___MASK54___ ___MASK30___ . In rural areas ___MASK48___ Low Saxon , a dialect ___MASK54___ Low German , and Saterland Frisian , a variety ___MASK54___ Frisian , are still spoken , but the number ___MASK54___ speakers is declining . The Weser is a ___MASK33___ in Northwestern ___MASK30___ . Formed at Hannoversch Münden by the confluence ___MASK54___ the rivers Fulda and Werra , it flows through ___MASK85___ , then reaching the Hanseatic - town Bremen ( see : Hanseatic League ), before emptying further north at Bremerhaven into the North Sea . On the opposite ( west ) bank is the town ___MASK54___ Nordenham at the foot ___MASK54___ the Butjadingen Peninsula ; thus , the mouth ___MASK54___ the ___MASK33___ is in ___MASK85___ . The Weser has an overall length ___MASK54___ . Together with its Werra tributary , which originates in Thuringia , its length is . ___MASK30___ , officially the Federal Republic ___MASK54___ ___MASK30___ , is a federal parliamentary republic in central - western Europe . It includes 16 constituent states , covers an area ___MASK54___ , and has a largely temperate seasonal climate . With about 82 million inhabitants , ___MASK30___ is the most populous member state ___MASK54___ the European Union . After the United States , it is the second most popular immigration destination in the world . ___MASK30___ ' s capital and largest metropolis is Berlin . Other major cities include Hamburg , Munich , ___MASK67___ , Frankfurt , Stuttgart and Düsseldorf . Wildemann is a town and a former municipality in the ___MASK80___ ___MASK54___ Goslar , in ___MASK85___ , Germany . It has been part ___MASK54___ the town Clausthal - Zellerfeld since January 1 2015 . It is situated in the west ___MASK54___ the Harz , northwest ___MASK54___ Clausthal - Zellerfeld . It was part ___MASK54___ the former " Samtgemeinde " (" collective municipality ") Oberharz . The Oker is a ___MASK33___ in ___MASK85___ , ___MASK30___ , that has historically formed an important political boundary . It is a left tributary ___MASK54___ the River Aller , in length and runs in a generally northerly direction . The Brocken , also sometimes referred to as the Blocksberg , is the highest peak ___MASK54___ the Harz mountain range and also the highest peak ___MASK54___ ___MASK48___ Germany ; it is located near Schierke in the German state ___MASK54___ ___MASK51___ - Anhalt between the rivers Weser and Elbe . Although its elevation ___MASK54___ is below alpine dimensions , its microclimate resembles that ___MASK54___ mountains ___MASK54___ about . The peak above the tree line tends to have a snow cover from September to May , and mists and fogs shroud it up to 300 days ___MASK54___ the year . The mean annual temperature is only . It is the easternmost mountain in northern Germany ; travelling east in a straight line , the next prominent elevation would be in the Ural Mountains in Russia . Infrastructure refers to structures , systems , and facilities serving the economy ___MASK54___ a business , industry , country , city , town , or area , including the services and facilities necessary for its economy to function . The Innerste is a ___MASK33___ in ___MASK85___ , ___MASK30___ . It is a right tributary ___MASK54___ the Leine ___MASK33___ and 95 km in length . The Söse is a right tributary ___MASK54___ the river Rhume , 38 kilometres long , in ___MASK85___ , Germany . ___MASK58___ and navigations are human - made channels for water conveyance ( supply ), or to service water transport vehicles . In the vernacular , both are referred to as ' ___MASK58___ ', and in most cases , the engineered works will have a series ___MASK54___ dams and locks that create areas ___MASK54___ low speed current flow . These areas are referred to as " ' slack water levels '," often just called ' levels '. The main difference between them is that a navigation parallels a river and shares part ___MASK54___ its waters , its drainage basin and leverages its resources by building dams and locks to increase and lengthen its long stretches ___MASK54___ " deep enough " slack water levels while staying in its valley . In contrast , a canal cuts across a drainage divide atop a ridge ( however humble ), generally requiring an external water source above the highest elevation . Many ___MASK58___ have been built at elevations towering over valleys and others water ways crossing far below . Cities need a lot ___MASK54___ fresh water and many ___MASK58___ with sources ___MASK54___ water at a higher level can deliver water to a destination where there is a lack ___MASK54___ water . The Roman Empire ' s Aqueducts were such water supply ___MASK58___ . Sewage is a water - carried waste , in solution or suspension , that is intended to be removed from a community . Also known as domestic or municipal wastewater , it is characterized by volume or rate ___MASK54___ flow , physical condition , chemical and toxic constituents , and its bacteriologic status ( which organisms it contains and in what quantities ). It consists mostly ___MASK54___ greywater ( from sinks , tubs , showers , dishwashers , and clothes washers ), blackwater ( the water used to flush toilets , combined with the human waste that it flushes away ); soaps and detergents ; and toilet paper ( less so in regions where bidets are widely used instead ___MASK54___ paper ). Whether it also contains surface runoff depends on the design ___MASK54___ sewer system . The Upper ___MASK12___ refers to the northwestern and higher part ___MASK54___ the ___MASK12___ mountain range in Germany . The exact boundaries ___MASK54___ this geographical region may be defined differently depending on the context . In its traditional sense , the term Upper ___MASK12___ covers the area ___MASK54___ the seven historical mining towns (" Bergstädte ") - Clausthal , Zellerfeld , Andreasberg , Altenau , Lautenthal , Wildemann and Grund - in the present - day German federal state ___MASK54___ ___MASK85___ . Orographically , it comprises the ___MASK12___ catchment areas ___MASK54___ the Söse , Innerste and Grane , Oker and Abzucht mountain streams , all part ___MASK54___ the larger Weser watershed . Drainage is the natural or artificial removal ___MASK54___ surface and sub - surface water from an area . The internal drainage ___MASK54___ most agricultural soils is good enough to prevent severe waterlogging ( anaerobic conditions that harm root growth ), but many soils need artificial drainage to improve production or to manage water supplies . The Dyke Ditch is the longest artificial ditch in the Upper ___MASK12___ in central Germany . Its purpose was to collect surface runoff for the operation ___MASK54___ the Upper ___MASK12___ mining industry from precipitation - heavy regions a long way away ( particularly from the Bruchberg and parts ___MASK54___ the Brocken massif ). It was laid in 1732 and continually extended eastwards until 1827 . Its original length was about 25 km ; this was successively shortened by water tunnels between 1820 and 1861 to around 19 km . It is a central component ___MASK54___ the Upper ___MASK12___ Water Regale . Its takes its name from the Sperberhai Dyke which is , in fact , an embankment on top ___MASK54___ which the Dyke Ditch runs in an aqueduct in order to cross a depression . The ___MASK12___ is the highest ___MASK11___ range in ___MASK48___ Germany and its rugged terrain extends across parts of ___MASK85___ , ___MASK51___ - Anhalt , and Thuringia . The name " ___MASK12___ " derives from the Middle High German word " Hardt " or " Hart " ( ___MASK11___ forest ), Latinized as " Hercynia ". The legendary Brocken is the highest summit in the ___MASK12___ with a height of above sea level . The Wurmberg is the highest peak located entirely within ___MASK85___ . Pumping stations are facilities including pumps and equipment for pumping fluids from one place to another . They are used for a variety ___MASK54___ infrastructure systems , such as the supply ___MASK54___ water to canals , the drainage ___MASK54___ low - lying land , and the removal ___MASK54___ sewage to processing sites . Surface runoff ( also known as overland flow ) is the flow ___MASK54___ water that occurs when excess stormwater , meltwater , or other sources flows over the Earth ' s surface . This might occur because soil is saturated to full capacity , because rain arrives more quickly than soil can absorb it , or because impervious areas ( roofs and pavement ) send their runoff to surrounding soil that cannot absorb all ___MASK54___ it . Surface runoff is a major component ___MASK54___ the water cycle . It is the primary agent in soil erosion by water . At , the Bruchberg in the Upper ___MASK12___ is the second highest ___MASK11___ in ___MASK85___ and the third highest in the ___MASK12___ mountains in North Germany . It lies between Altenau and Torfhaus in the middle ___MASK54___ the ___MASK12___ National Park . The Bruchberg is more like a plateau and has no real summit . This plateau is partly covered with trees , but on the sunny southern slopes the trees have largely died as a result ___MASK54___ bark beetle infestation ( see photograph below ). Following this insect destruction , a new natural forest , rich in its variety ___MASK54___ species , is now growing in the heart ___MASK54___ the ___MASK12___ National Park .
