Wasserwerk Koblenz-Oberwerth, Waterworks and heritage monument in Oberwerth, Koblenz, Germany.
Wasserwerk Koblenz-Oberwerth is a water treatment facility featuring a distinctive yellow brick structure with red decorative elements and rounded arch details in early industrial style. The plant draws groundwater from below the surface and includes treatment systems located on site.
The facility began serving the region in 1886 on what was once an island in the Rhine and underwent major rebuilding during the mid-1900s. These upgrades helped the plant meet changing needs as the region grew.
The building shows how people in the early 1900s approached water technology and valued safe supplies. It reflects the connection between industrial engineering and everyday community life.
The site sits on what was once an island in the Rhine and is accessible from central Koblenz, though public visits are restricted. Check ahead if you want to see inside, as this is an active facility with safety requirements.
Since 1964, the facility has used a special process to remove excess carbonic acid from drinking water. This particular method was needed to make the groundwater suitable for everyday use.
