It serves a population of 4,440 and operates with secondary treatment, processing an average daily flow of 600 cubic meters. The plant is part of the municipal wastewater infrastructure managed by the eThekwini Metropolitan Municipality. As a secondary treatment facility, Dassenhoek meets the basic standards for organic matter and suspended solids removal. South Africa's wastewater treatment regulations, under the National Water Act and Water Services Act, require compliance with discharge standards. For a plant of this scale, secondary treatment is typical and aligns with national norms for small to medium agglomerations. The treated effluent from Dassenhoek is discharged into the local watershed, which ultimately drains into the Indian Ocean via the coastal rivers of KwaZulu-Natal. The region's aquatic ecosystems, including estuaries and coastal zones, benefit from proper treatment that reduces nutrient and pathogen loads, supporting biodiversity and water quality downstream.

Dassenhoek's treated effluent enters the drainage network of the eThekwini coastal area, flowing into the Indian Ocean. The receiving water bodies support diverse aquatic life, including estuarine and marine species. Proper secondary treatment helps mitigate eutrophication risks and protects downstream ecosystems, which are important for local fisheries and tourism.
