The area supports diverse aquatic life and is part of the Swiss Plateau's ecological network, contributing to the protection of downstream habitats.

CUDREFIN is situated near Lake Neuchâtel, part of the Swiss Plateau's hydrological system. Treated wastewater likely enters a local stream that drains into the lake, which is a key water body in the Rhine basin. The lake supports diverse aquatic ecosystems, including fish species such as perch and pike, and is an important stopover for migratory birds. Advanced treatment helps minimize nutrient loading, protecting water quality in this ecologically sensitive region.
