Kei Mouth Wastewater Treatment Plant, Great Kei Local Municipality, Eastern Cape

Kei Mouth wastewater treatment plant is located in the coastal town of Kei Mouth, within Great Kei Local Municipality in the Eastern Cape province of South Africa. The facility serves a population of approximately 2,319 residents, reflecting a small coastal community. The plant is situated near the Strandloper Trail, close to the Indian Ocean shoreline. The plant operates with secondary treatment, which is the standard level required under South Africa's wastewater regulations for municipal discharges. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. South Africa's Department of Water and Sanitation oversees wastewater treatment standards through the National Water Act and Water Services Act. The treated effluent is discharged into the local environment near the coast, ultimately reaching the Indian Ocean. The receiving water body is not explicitly named, but the plant's proximity to the coast means the discharge may affect nearshore marine ecosystems. The area supports diverse coastal and estuarine habitats, including the nearby Kei River mouth, which is ecologically important for fish and bird species.

The plant discharges treated wastewater into the coastal environment near the Indian Ocean, likely via a local watercourse or direct marine outfall. The receiving waters are part of the Amathole coastal region, which supports estuarine and marine ecosystems. The nearby Kei River mouth provides critical habitat for migratory birds and fish species. The discharge contributes to nutrient loads in nearshore waters, potentially affecting local water quality and marine biodiversity.
