Environmental context
ENSUES discharges treated wastewater into the Mediterranean Sea, specifically into the Gulf of Lion, which supports diverse marine life including seagrass meadows and fish populations. The coastal waters are ecologically sensitive due to tourism and fishing activities. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in this semi-enclosed sea.
