The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Indian Ocean via the Mzimkulu River or nearby coastal streams. The receiving environment supports diverse aquatic life and is important for local fisheries and tourism. Proper treatment helps protect the sensitive coastal and marine ecosystems along the KwaZulu-Natal coastline.

The plant discharges into the Mzimkulu River catchment, which flows into the Indian Ocean near Port Shepstone. This coastal region supports estuarine habitats and mangrove ecosystems that are critical for fish breeding and migratory bird species. The area's subtropical climate and high rainfall make effective wastewater treatment essential to prevent nutrient loading and protect downstream marine biodiversity.
