31 irrigation machines from Bauer operate under the unique Braunschweig model in northern Germany. The local wastewater association secures the production of food and energy plant production in this way.
The Braunschweig Waste Water Association is a water and soil association located in Braunschweig in northern Germany and is responsible for wastewater treatment in Braunschweig and the surrounding area. With its 80 employees and an annual revenue of approximately 35 million euros, the association is considered a mid-sized business in Germany.
The Braunschweig model developed by the association is unique throughout Germany and combines wastewater from the city with bioenergy from the surrounding rural areas to create a water-food-energy cycle:
The wastewater is treated mechanically and biologically, and the resulting clean water is used to irrigate the agricultural lands of the association members. The energy plants cultivated in the irrigated regions are processed in the association’s own biogas plant for CO²-neutral production of biogas. This secures the supply of several thousand households in Braunschweig with power and heat.
The wastewater association currently used 31 irrigation machines from Bauer to distribute the treated water. The oldest Bauer irrigation machine has been in operation already since 2003 and has exhibited no major problems in this time. The machines are in operation from February to October, for an average of 2,000 operating hours per year. Thanks to the full galvanization, the Bauer machines are reliable, long-lasting and operate with low pressure losses. For this reason, the Braunschweig Waste Water Association is already planning to purchase further Rainstars in future.
