Sewage treatment plants
Munich city drainage operates two sewage treatment plants, Gut Großlappen and Gut Marienhof . Due to its location in the low-lying north of Munich, the sewage flows through the Munich canal system from the south from almost all parts of the city to the sewage treatment plants without pumps.
Good large rag
From 1916, the city of Munich bought the grounds belonging to Gut Großlappen and had the large municipal sewage treatment plant built there in 1926. The Gut Großlappen sewage treatment plant ⊙ is located in the Freimann district of Munich on Fröttmaninger Berg between the Munich - Nuremberg motorway (A9) and the Freisinger Landstrasse . A digestion plant with four 35 meter high digestion towers was built between 2003 and 2006 for biogas production . Due to their glossy cladding, these represent an interesting architectural contrast to the Allianz Arena opposite .
The Gut Großlappen sewage treatment plant has the following cleaning functions:
- biological purification stages including nutrient elimination
- mechanical cleaning with sand traps and settling basins
- biological cleaning, the aeration tanks of which are equipped with anaerobic and aerobic zones for biological phosphorus and nitrogen removal
- The cleaning performance of the wastewater treatment plant is monitored by an in-house laboratory
- Sewage sludge incineration plant (since 1998)
Most of the treated wastewater flows through underground channels under the Isar to the main E.ON Wasserkraft pumping station between Unterföhring and Ismaning . From this it is pumped into the five meters higher former fish ponds of the Birkenhof pond on the Ismaninger reservoir and partly directly into the reservoir. From there it flows through the Neufinsing power plant into the Mittlere-Isar-Kanal and at its end into the Isar.
Gut Marienhof
In 1989 Gut Marienhof ⊙ was built in the Dietersheim community . It has the following cleaning levels:
- biological purification stages including nutrient elimination
- mechanical cleaning with sand traps and settling basins
- biological cleaning, the aeration tanks of which are equipped with anaerobic and aerobic zones for biological phosphorus and nitrogen removal
- Sand filter for further removal of suspended matter
- Wastewater disinfection system to reduce germs and improve the hygienic water quality of the Isar
- The cleaning performance of the wastewater treatment plant is monitored by an in-house laboratory
