The facility serves a population of around 8,880 residents, classifying it as a small to medium agglomeration under South African water management standards. As a municipal wastewater treatment plant in South Africa, Hillcrest operates under the National Water Act and Water Services Act, which mandate appropriate treatment levels to protect water resources. For a plant of this scale, secondary treatment is typically required to meet effluent quality standards before discharge. The plant's treated effluent ultimately drains into local watercourses within the uMngeni River catchment, which flows to the Indian Ocean. This catchment supports diverse aquatic life and provides water for downstream communities and agriculture, making effective treatment essential for environmental and public health.

Hillcrest is situated in the uMngeni River basin, which drains into the Indian Ocean near Durban. The uMngeni River and its tributaries support a variety of freshwater species and provide water for irrigation and domestic use. The plant's discharge contributes to the river's flow, and proper treatment is critical to prevent nutrient loading and protect downstream ecosystems, including estuarine habitats along the coast.
