ESSERTINES_EPAUTHEYRES is a municipal wastewater treatment plant located in Epautheyres, within the commune of Essertines-sur-Yverdon in the Vaud canton of Switzerland. The facility serves a small population of 121 residents, reflecting its role in a rural or peri-urban setting. The plant provides secondary treatment, which is the standard biological treatment stage required under Swiss water protection regulations. With a designed capacity of 283.00 m³/day and an actual discharge volume of 54.93 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into a local watercourse that ultimately drains into the Rhone River basin via the Venoge or other tributaries of Lake Geneva. The plant's operation helps protect the sensitive aquatic ecosystems of the region, which support diverse freshwater species and contribute to the overall health of the Rhone watershed.
Environmental context
The plant discharges into a small stream within the Rhone River basin, which flows into Lake Geneva (Lac Léman) and then via the Rhone River to the Mediterranean Sea. The local watershed supports diverse aquatic life, including fish species such as brown trout and grayling, and is part of a region with high ecological sensitivity due to agricultural runoff and urban pressures.
