Woltmershausen gas works
In the first half of the 20th century, the Woltmershausen gasworks supplied the city of Bremen with energy . It supplied town gas for lighting, heating and cooking purposes as well as for hot water preparation. In some old Bremen houses, there are still pipes and connections for gas lighting in addition to the electrical lines .
history
In 1901, a new gas works was built in Woltmershausen west of the railway line to Oldenburg , as the capacity of the old gas works on Schlachthofstraße near the main train station was no longer sufficient. The city of Bremen bought the property in what was then Woltmershausener Feldmark. 70,000 cubic meters of gas could now be produced daily from hard coal in 30 furnaces . In 1902 Woltmershausen was incorporated into the city of Bremen. The capacity could be increased to 120,000 cubic meters. Public lighting in Bremen was powered by gas until 1917. The Woltmershauser Canal was expanded into a coal port. For around 65 years, the city was supplied with self-generated gas from this gas works. Three gasometers served as storage. Bomb hits in World War II caused extensive damage - particularly to the pipe network, so that the gas supply had to be cut in March 1945. In 1954 a new and bigger gasometer was built, which at 83 meters was the second tallest building after the cathedral and could store more than 100,000 cubic meters of gas. The tower was green, but the upper part was painted with red and white rectangles based on the Bremen bacon flag . For decades it shaped the entrance to the Woltmershausen district. The residents of the gasworks were annoyed by the smells of sulfur compounds , ammonia and benzene - at that time still unavoidable side effects of coal processing. Since the energy demand of the city of Bremen continued to grow, town gas was no longer sufficient from the 1960s onwards. The Stadtwerke Bremen AG moved then coke oven gas from the Ruhr area, which had the same composition as town gas. The gas supply was switched to natural gas between 1968 and 1972, and an underground cavern was set up as storage in the Burglesum district . The gasometer was finally demolished in 1984 because of the high operating costs. Today the Woltmershausen plant with administration, training workshops and warehouse is located on the site .
Redevelopment
After the shutdown of the gasworks and the demolition of other buildings that were no longer required, the site was examined for contaminated sites . In some cases, drilling tests were carried out up to a depth of 16 meters. The content of numerous polycyclic aromatic hydrocarbons (PAHs for short) was particularly noticeable, most of which could be recognized by the benzene or tar-like odor and some of them reached the groundwater. The renovation of the site began in 1987, the costs were then estimated at more than 6 million DM.
The cleaning, treatment and replacement of the contaminated soil took place with the participation of various companies, as the originally commissioned company Umwelt Nord GmbH did not work as successfully as originally assumed, the excavated soil was partially stored elsewhere and finally became insolvent in 2003 . In 1990 the municipal utilities commissioned another report to determine the remaining load. As a result, further measures were necessary, some of which lasted until 2006.
