The city of Cloppenburg operates a municipal sewage treatment plant with a high proportion of industrial dischargers (in total approx. 190,000 PE) and was last upgraded to the current state of the art in the course of the extensive 6th expansion measure. In addition to the usual sewage treatment of municipal sewage treatment plants, a strip plant and biofiltration (Biofor) are in use at the site.

Due to age, the aggregates of sludge dewatering (chamber filter press, daily sludge seizure average about 135 m 3 ) and must be renewed.

On the basis of an engineering preliminary investigation with regard to sustainable dewatering aggregates, centrifuges were developed as a preferred variant.

On the basis of the available documents, the planning process (mechanical engineering / E / MTR technology and buildings) for the renewal of sludge dewatering shall be started and accompanied until the final realization of the measure.

The performance picture of the engineering services according to the HOAI 2013 includes the following points:
