The Emden water tower is located in Abdenastraße near today's main train station . The building from the years 1910 to 1912 is owned by Stadtwerke Emden and is still in operation. At 42 meters high, it towers over most of the city's buildings and is an important example of a technical structure from the beginning of the 20th century in Emden . The water tower has been a listed building since 1999.
Building
The water tower is the first structure in Emden to be built using reinforced concrete . The container rests on two concentric supports. It is supported by 10 reinforced concrete pillars that are connected to each other by cross braces. The pillars rest on a foundation made of 260 piles 15 meters in length.
The pipelines and the spiral staircase to the ascent are protected in the closed inner part of the three-story substructure. The container is surrounded by a decagonal plastered reinforced concrete jacket, which is used for insulation. A two-level roof, conical at the top, completes the building at the top.
The 1000 m³ water tank has a composite bottom, a combination of an outer annular flat bottom with an inner domed bottom. Because of the large container diameter of 12.5 meters, a pure dome floor would have removed too much volume. A passage is cut out in the middle of the container, through which one can get to the top container platform in the roof cone.
Development of the Emden water supply
Like many coastal cities, Emden had problems getting enough clean drinking water . The groundwater was salty due to the proximity of the North Sea. Before setting up the central supply, the Emder collected the rainwater in their own cisterns . When the water demand of the growing port and trading city increased by leaps and bounds in the 19th century, planning began for a central water supply . It was concluded that good quality groundwater could only be extracted outside of Emden. After test drilling, a waterworks was built in 1896/97 on a Geest island in Tergast, more than 11 kilometers away . The water reached Emden via a pipeline.
The Tergaster waterworks has been expanded and modernized several times. It belongs to the Stadtwerke Emden and still supplies the city today. From 20 deep wells and three shallow wells, water is pumped from a freshwater lens and pushed to Emden via two drinking water pipes. In 2006, 3.5 million cubic meters of groundwater were treated in Tergast to meet the needs of over 50,000 people.
