Usage tips
Compound structure
'Die Kläranlage' (wastewater treatment plant) is a compound noun made from the verb 'klären' (to clarify, to clean) and the noun 'die Anlage' (facility, plant). So it is literally a facility that clarifies or cleans something—in this case, wastewater.
EXAMPLE
Die Gemeinde plant den Bau einer neuen Kläranlage.
The municipality is planning the construction of a new wastewater treatment plant.
Word family
The verb 'klären' (to clarify, to clean) in the word is related to the adjective 'klar' (clear). The goal of a Kläranlage is to make dirty water 'klar' (clear) and clean again. This connection helps you remember its function.
EXAMPLE
Nach der Reinigung in der Kläranlage ist das Wasser wieder klar.
After treatment in the wastewater treatment plant, the water is clear again.
Typical collocations
The central noun associated with a wastewater treatment plant is 'das Abwasser' (wastewater). Typical verbs describe the operation of the plant, e.g. 'eine Kläranlage betreiben' (to operate a wastewater treatment plant), 'bauen' (to build), or 'modernisieren' (to modernize).
EXAMPLE
Das gesamte Abwasser der Region wird in dieser Kläranlage gereinigt.

Kläranlage vs Kanalisation
sewer system
'die Kanalisation' and 'die Kläranlage' both have to do with wastewater. The difference lies in the place and the function. 'die Kanalisation' is the underground network of pipes through which wastewater flows away. 'die Kläranlage' is the technical facility where this wastewater is treated. The words can be confused because the water first flows through the sewer system and is later treated in the wastewater treatment plant. As a simple guide: 'die Kanalisation' transports; 'die Kläranlage' cleans.
Kläranlage
In der Kläranlage wird das Abwasser gereinigt, bevor es in den Fluss gelangt.
At the wastewater treatment plant, the wastewater is treated before it reaches the river.
Kanalisation
Nach dem starken Regen war die Kanalisation in einigen Straßen überlastet.
After the heavy rain, the sewer system was overloaded on some streets.
