Nseleni wastewater treatment plant is located at the South32 Hillside Aluminium Smelter in Richards Bay, within the uMhlathuze Local Municipality of KwaZulu-Natal, South Africa. The plant serves a population equivalent of 9,504 and is designed with a capacity of 1.00 (likely million liters per day or similar). It operates in an industrial context, supporting one of the world's largest aluminum smelters. As a South African plant, Nseleni falls under the national regulatory framework administered by the Department of Water and Sanitation, which sets discharge standards under the National Water Act (Act 36 of 1998) and the Water Services Act. The plant's treated effluent likely discharges into the Mhlathuze River catchment, which flows into the Mhlathuze Estuary and then into the Indian Ocean at Richards Bay. This estuarine environment supports diverse aquatic life and is an important migratory corridor for birds and marine species. The plant's proximity to the coast (within 50 km) underscores the need for effective nutrient removal to protect downstream ecosystems.
Environmental context

This estuarine system is ecologically sensitive, supporting a variety of fish, bird, and invertebrate species. The plant's discharge must comply with South African water quality guidelines to prevent eutrophication and protect downstream aquatic habitats.
