Marselle Wastewater Treatment Plant, Ndlambe Local Municipality, Eastern Cape

Marselle is a wastewater treatment plant located in Boesmansriviermond, within the Ndlambe Local Municipality of the Eastern Cape province, South Africa. The plant serves a population of approximately 7,400 residents and has a designed capacity of 1.00 million liters per day, indicating a small-scale facility typical of coastal settlements in the region. As a South African plant, it operates under the National Water Act (Act 36 of 1998) and the Water Services Act (Act 108 of 1997), which set standards for wastewater treatment and discharge. The plant discharges into the local environment, likely into the Boesmans River system or directly into the Indian Ocean via the nearby coastline. The Eastern Cape region features sensitive estuarine and marine ecosystems, including the Boesmansriviermond estuary, which supports diverse aquatic life and is important for local biodiversity.

The plant is situated near the Boesmans River mouth, which flows into the Indian Ocean. The Boesmansriviermond estuary is a dynamic coastal ecosystem that supports fish, birds, and invertebrates. Downstream, the river and estuary provide critical habitat and nursery grounds for marine species. The region's coastal waters are ecologically sensitive, and proper wastewater treatment is essential to prevent nutrient pollution and protect marine biodiversity.
