Stanford WWTW - Secondary Wastewater Treatment in Overstrand, Western Cape

Stanford WWTW is a municipal wastewater treatment plant located in Stanford, within the Overstrand Local Municipality of the Western Cape province, South Africa. The plant serves a population of approximately 3,700 people, classifying it as a small agglomeration under South African water management frameworks. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. With a discharge volume of 500 cubic meters per day, the facility operates under South Africa's water quality regulations, which require compliance with the National Water Act and relevant discharge standards for coastal environments. The treated effluent is discharged into the local environment, ultimately reaching the Atlantic Ocean via the Klein River estuary. The coastal location means the plant's discharge must meet stringent standards to protect the sensitive marine ecosystem, including the nearby Walker Bay, which supports diverse aquatic life and is an important area for migratory birds and marine species.

The plant discharges into the Klein River system, which flows into the Klein River estuary and then into Walker Bay on the South Atlantic coast. This coastal environment supports diverse marine life, including fish nurseries and migratory bird populations. The proximity to the coast requires careful management of nutrient loads to prevent eutrophication and protect the estuarine and marine ecosystems.
