Braunschweig (Germany)

Braunschweig is a city in Lower Saxony, Germany. Nowadays, Braunschweig is the second-largest city in Lower Saxony and a major centre of scientific research and development. It has an area of 192 km² and 248,023 inhabitants. The agricultural and food industry has always occupied a central role in Lower Saxony: it is, after the car industry, the state's second-largest business sector. Although Germany is considered to be a water rich country with available water resources of 188 billion m3, in the region of Braunschweig, the overall balance over the last 50 years has been negative, which led to a stagnating recharge of groundwater. Most of the agricultural area in the region is characterized by sandy soils with low water-holding capacity which makes an intensive irrigation necessary. Taking that in account and in order to prevent falling groundwater levels the reuse of reclaimed water in agriculture is essential in this area.
For irrigation of its fields AV-BS uses a mix of reclaimed water (90%) from the WWTP and groundwater (10%) which is abstracted on-site.
