The plant serves a population of approximately 11,839 residents in the Harding area, situated along the N2 highway. As a municipal facility, it plays a key role in managing wastewater for this community in the southern part of the province. Under South Africa's National Water Act and Water Services Act, wastewater treatment plants serving communities of this scale are expected to meet minimum effluent quality standards. The plant's treatment processes align with national guidelines for secondary treatment, which are designed to protect receiving water bodies and public health. Regulatory oversight is provided by the Department of Water and Sanitation, which issues permits and monitors compliance. The treated effluent from the plant discharges into local watercourses that ultimately drain into the Indian Ocean via the Mzimkhulu River system. This watershed supports diverse aquatic ecosystems and is important for downstream water users, including agriculture and rural communities. The plant's operation is critical for maintaining water quality in this ecologically sensitive region.

The plant discharges into the Mzimkhulu River catchment, which flows through the KwaZulu-Natal coastal plain before reaching the Indian Ocean. This watershed supports a variety of freshwater and estuarine habitats, including wetlands that provide critical ecosystem services such as water purification and flood regulation. The downstream environment is ecologically sensitive, hosting diverse aquatic species and serving as a migratory corridor for fish and birds.
