Klärwerk Bottrop

Klärwerk Bottrop is a wastewater treatment facility in Bottrop consisting of four large digestion towers alongside extensive infrastructure for cleaning contaminated water. The plant processes sewage from several surrounding cities in the Ruhr Valley region.

The first treatment facility at this location was built in 1929, but the current modern plant was constructed between 1991 and 1996 on a much larger scale. This new construction marked a major advance in regional wastewater management.

The facility serves as an educational destination where visitors can learn about water treatment processes and environmental protection through guided tours.

The site is very large and used primarily for operational purposes, so visitors should rely on organized tours to understand how it functions. Access is only available through guided visits and requires advance arrangement.

The facility uses biogas from sludge fermentation to generate electricity and operates part of its own vehicle fleet with this energy. This makes it an example of energetic self-sufficiency in wastewater management.
