Hout Bay Sewage Scandal: Cape Town City Breaches Environmental Permit Conditions

An environmental controversy has surfaced in Hout Bay, Cape Town, where the City has been found to be discharging sewage volumes into the ocean that exceed permissible limits, according to reports authenticated by the City's data. This revelation compromises the ecological integrity of marine environments and reflects non-compliance with stringent environmental permits and national legislation.

The City of Cape Town operates a marine sewage outfall system, intended to handle effluent from the Hout Bay area. This system pushes raw sewage through a three-millimeter grid to filter out solids before discharging it through a pipeline extending 1.7km offshore at a depth of 37 metres. The system, one of the three marine outfalls in Cape Town, was stipulated to not exceed five million litres of daily sewage disposal under a permit issued by the Minister of Forestry, Fisheries and the Environment (DFFE), Barbara Creecy, in 2019.

Documentation secured through a Promotion of Access to Information Act (PAIA) request by ActionSA provincial chairperson Michelle Wasserman unearthed that the City has been non-compliant with the permit conditions, exceeding the daily five-million-litre discharge cap on 104 days out of the scrutinized 181-day period. Astonishingly, on some occasions, more than 12.5 million litres were released into the sea, when the City's infrastructure is designed for a maximum of just 9.6 million litres per day.

The City's infractions do not end with the volume of sewage; the quality of the effluent discharged has consistently failed to meet the minimal standards for sewage disposal into marine environments. Reports indicate that the levels of suspended solids, chemical oxygen demand, and pH in the sewage did not conform to the required specifications, and in several instances, the City failed to measure the levels of toxic substances like arsenic, cadmium, and mercury which are mandated to be reviewed weekly.

A critical component of the permit was the establishment of a Permit Advisory Forum, tasked with quarterly discussions of any permit breaches. However, responses from the City following the PAIA request by Wasserman presented a grim picture of compliance, revealing that the forum was never convened, failing an essential oversight function mandated by the permit.

ActionSA has, in response, filed a criminal charge under the Integrated Coastal Management Act of 2008. The Act enforces the obligations for the management of coastal resources, and the City's failure to adhere to the permit conditions amounts to a direct contravention.

Confronted with these allegations, City water and sanitation mayco member Zahid Badroodien confirmed the City’s adherence to current permit and license conditions, as issued by the DFFE. He further mentioned the commissioning of a study to ascertain the feasibility and expense of treating sewage before ocean disposal, or rerouting it to existing sewage treatment facilities. Badroodien acknowledged Minister Creecy's directive for public participation on the permits regarding the three city outfalls and anticipated the draft report's completion to enable further community discussions.

The City of Cape Town's breach of the Hout Bay sewage discharge permit raises significant environmental concerns and reflects negligence in adhering to established legal and environmental protection frameworks. The resultant marine pollution poses a threat not only to marine life but also to human health and the livelihoods of communities dependent on these marine ecosystems.
