The common waste water treatment plant of Oyten/Ottersberg is, besides the municipal charge, also developed for the indirect food purification process. Nowadays, the, at end of the 90’s extended, common waste water treatment plant does not meet the minimum legal requirements. Especially in the biological part of the treatment plant this is justified by the expelling sludge from the secondary clarification process. Besides the fundamental reorganization of the technical process management in the area of the mechanical and biological stage, extensive measures to renovation were carried out, especially those measures on the part of wastewater and sludge treatment.
The realization of the upgrade toke place in two separated construction stages. The entire construction work was completed in the spring of 2013.

The Fraport AG has extended the airport Frankfurt Rhine/Main acc. to the forecasted demand in the year 2020. In focus has been the new construction of the runway Northwest. Beside the runway new taxiways for connection to the already existing infrastructure needed to be realized. In addition two bridges crossing a motorway as well as a highspeed railway track has been built. The rain water from the runway as well as of all taxiways is captured by slot channels ans subsequently forwarded through the new sewer system to the rainwater retention basins. From there the water will be forwarded to either infiltration, to the river Main or to the sewage treatment plant according to the degree of pollution
