The treated effluent from L'Abbaye_Le Pont flows into the local river system, eventually reaching Lake Geneva (Lac Léman), one of Europe's largest freshwater lakes. The lake supports diverse aquatic life and provides drinking water for millions. The plant's advanced treatment helps maintain the lake's water quality, protecting its ecological balance and recreational value.

The plant discharges into the Orbe River watershed, which flows into Lake Geneva via the Rhone River. Lake Geneva is a deep, oligotrophic lake that supports a variety of fish species, including Arctic char and whitefish, and is a critical drinking water reservoir. The advanced treatment at L'Abbaye_Le Pont reduces nutrient loading, helping to prevent eutrophication and preserve the lake's clear waters and biodiversity.
