For my waste water, the ARA Esslingen und Oetwil am See is responsible. It covers 4848 people from Oetwil am See and 8888 people from Esslingen (2020). However, the size of the sewer is for 17,000 inhabitants. The ARA is in Esslingen 8133 and was founded in 1965.
The wastewater is collected via urban drainage and flows into the main sewer system. Due to the topographical location of our communities, part of the wastewater must be conveyed to the main collection sewer with the help of nine pumping stations.
Because the wastewater treatment plant cannot receive an unlimited amount of wastewater (210l/s), the municipality of Egg and Oetwil am See also have four additional rainwater retention basins at their disposal in case of large rainfalls, which can be used to collect the first wastewater accumulation.
The cleaning efficiency is 98%.
