Why Bays of Sewage?

Water Is A Human Right — Know Your Rights

Written into the South African Constitution in 1996, highlighting our environmental rights:
Chapter 4, Section 24 of the Constitution states that:

Everyone has the right to:

  • an environment which is not harmful to their health or well-being 
  • have the environment protected for the benefit of present and future generations through reasonable legislative and other measures that:
  • prevent pollution and ecological degradation 
  • promote conservation 
  • secure ecologically sustainable development and use of natural resources, while promoting justifiable economic and social development.

Section 24 has two important consequences:

  • It protects our health and well-being 
  • It places a duty on the state, on business, and on all South Africans, to prevent pollution and other damage to the environment, and to promote conservation and sustainable development.

Every government authority national, provincial and local has a duty to take reasonable steps, in its current functions as well as future plans, to prevent pollution, promote conservation and ensure sustainable development.

Ocean Alert – We Have A Problem!

You can smell it, you can feel it and you can see it… it is killing our oceanlife in the Atlantic Bays of Cape Town and it must stop now.

Humans and the products, chemicals, plastics and pharmaceuticals we consume mostly ends up in the ocean.

“The presence and levels of fifteen chemicals of emerging concerns, including five perfluorinated compounds (PFCs), two industrial chemicals, seven pharmaceuticals and one personal care product, were evaluated in biota, seawater and sediments obtained from near-shore coastal zone in Camps Bay, Cape Town, South Africa. Eight compounds were found in seawater, and between nine to twelve compounds were quantified in marine invertebrates, sediment and seaweed. Diclofenac was the prevalent pharmaceutical with a maximum concentration of 2.86 ng/L in seawater, ≥110.9 ng/g dry weight (dw) in sediments and ≥67.47 ng/g dw in marine biotas. Among PFCs, perfluoroheptanoic acid was predominant in seawater (0.21-0.46 ng/L). Accumulation of perfluorodecanoic acid (764 ng/g dw) as well as perfluorononanoic acid and perfluorooctanoic acid (504.52 and 597.04 ng/g dw, respectively) was highest in samples of seaweed. The environmental risk assessment carried out in this study showed that although individual pollutants pose a low acute and chronic risk, yet individual compounds each had a high bioaccumulation factor in diverse marine species, and their combination as a complex mixture in marine organisms might have adverse effects upon aquatic organisms. Data revealed that this Atlantic Ocean marine protected environment is affected by the presence of numerous and diverse emerging contaminants that could only have originated from sewage discharges. The complex mixture of persistent chemicals found bioaccumulating in marine organisms could bode ill for the propagation and survival of marine protected species, since many of these compounds are known toxicants.

Reference: The burden of emerging contaminants upon an Atlantic Ocean marine protected reserve adjacent to Camps Bay, Cape Town, South Africa

Corporates: Plastic pollutants from packaging, chemicals in pesticideds, building materials and oils that are dumped by restaurants into drains are highly toxic to our environment. 

Government dumps Raw Sewage into the sea: Sewage pollution is everything we flush down the loo or wash down the drain that is released into the environment through sewer overflows, or that washes off the land and roads. The disposal of our sewage is the responsibility of the City of Cape Town government, which we pay for each month in our rates bill. And no the sea does not dilute it, the ocean holds it in the bays and the sealife suffer the consequences.

The 3 marine outfalls contribute to these contaminants in our bays and are a health risk to our marine protected areas, the ocean life and our communities. Each day a total of 55 million litres of Preliminary Raw Sewage is pumped into our bays made up from Hout Bay; Camps Bay and Green Point.  Green Point MOP falls within the Robben Island Marine Protected Area and the TMNP, which is a violation to the permit issued by the national government.

Aside from the MOPs placed in MPA and TMNP reserves, the City falsely declares the pipeline length are a sufficient distance from the pumps station yet omits the Camps Bay and Hout Bay MOPs discharge points are significantly closer in proximity to the shoreline whilst ignoring these bays also trap the discharge with any onshore wind, currents and prevailing swell direction. 

To understand these kind of volumes, imagine 44 000 petrol tanks lined up going out just into Camps Bay alone every single day or 41/2 Olympic size swimming pools of raw sewage splashing 700m off Maidens Cove.

How is our sewage ”treated”?

Wastewater is treated in 3 phases: primary (solid removal), secondary (bacterial decomposition) and tertiary with extra filtration.

The City of Cape Town does not do this for the the Atlantic Coast, but only does a preliminary treatment. And while many countries do dispose of their sewage into the ocean, it should be treated, never simply macerated.

Preliminary treatment is the removal of floating materials, grit and oily substances. To put it simply it is a treatment that is supposed to remove inorganic matter like tampons, toilet paper, etc and then it is mascerated and released in its raw state into the ocean.  Chemicals, pharmaceuticals and microplastics all flow into the ocean. This is unacceptable and a serious health risk for all!

A Growing City With Bigger Demands On Resources

The PROBLEMS with the current sewar pipelines or MOP’s (Marine Outfall Pipes), some of which are 100 years old!!… is that we all need an upgrade after a while…. (population of Cape Town when the pipes were built was 130 000 people compared to today a population of 5 million people and growing – why are we using the same system to service so many more people?)

Here is the history of our MOP’s explained:

The city regularly likes to claim the outfalls are meeting ‘their design objectives’.

Here is an example in this article ‘Experts raise flags’: https://www.iol.co.za/capetimes/news/experts-raise-flags-over-cape-town-beaches-e9655cd7-ebf2-4b98-8d69-b3ca9b10d16d

“Their overall key conclusion is that the marine outfalls are meeting their design objectives in reducing potential deleterious ecological and/or human health effects.”

But what are these objectives? To disperse sewage, as per ‘the science of the day’? The Camps Bay outfall dates back to 1977. At that time we also put lead in petrol and in paint, and we mined for asbestos without proper protection for workers, and put the asbestos in water pipes and school roofs, because ‘we didn’t know better back then’.

The Hout Bay permit states: “The total pipeline length is 2162m from the highwater mark” In fact, pipe length is not relevant. All that matters is the distance from the outfall discharge point, to the nearest shore. When one puts the outfall pump station co-ordinates, plus the discharge point co-ordinates, as on the outfall permits, into Google Earth, and use the Google Earth ruler to measure distances, the following is shown: • Hout Bay’s discharge point is only roughly 700m from the land, which is a nature reserve (and even closer to where surfers participate in the International Big Wave event at ‘Dungeons’ surf spot). 

  • Hout Bay’s discharge point is a mere 1000m from the pump station.

Yet in articles like the below, the distance is presented as being further: From the Daily Maverick on November the 17th Sewage in the sea — City marine outfall discharge falls foul of Hout Bay permit conditions (https://www.news24.com/news24/southafrica/news/sewage-in-the-sea-city-fails-to-meet-hout-bay-permit-conditions-20231117)

Quote: “Raw sewage from Hout Bay is… pumped through a pipe that extends 1.7km out to sea” 1.7km from where? Not from the pump station! So it is easy to see how this creates a false impression that the sewage is being pumped out much further than in reality. 

Argument and example 2 

The Camps Bay permit states: “The total pipeline length is 1350m from the highwater mark.” Yet Google Earth shows Camps Bay’s discharge point is a mere 600m from then nearest rocks, and only 700m from Maiden’s Cove tidal pool. 

Here is an example showing how the public are presented with misleading information. 

This article from News 24 on April 23rd, titled “Untreated sewage is putting Cape Town’s endangered penguins at risk. The city is pleading poverty”

https://www.news24.com/news24/southafrica/news/untreated-sewage-is-putting-cape-towns-endangered-penguins-at-risk-the-city-is-pleading-poverty-20230403

Quote: The City of Cape Town is permitted to release screened sewage into the ocean at Green Point, Hout Bay and Camps Bay via pipes about 1.7km, 1.2km and 1km out to sea This suggests Camps Bay sewage is discharged 1km out to sea. Again, 1km from where? Certainly not 1km from Maiden’s Cove tidal pool. 600m from the nearest shore is NOT 1km out to sea. The public are being misled as to the true distances from shore. 

Health Risks

“In 1926 the MOH pointed out that the Green Point outfall received sewage from the Infectious Diseases Hospital located in that area. He believed that this probably accounted for the high incidence of enteric fever, especially to the east of the outfall because ‘much more stercus is usually found to the east of the outfall, apparently owing to the circumstances that the surf tends to cast in on to that side.’ Neil Overy

An opinion from Prof Leslie Petrik – UWC wrote commenting of the pathological report, ‘This relates to antibiotic resistant pathogens. Cleaning these infections is becoming more and more challenging due to ‘superbugs’ that arise because of their constant exposure to chemicals (read antibiotics and disinfectants) in sewage. The bacteria that survive the contact with chemicals are resistant. It is one of the biggest challenges globally and one of the reasons why chemical laden sewage needs proper treatment to ensure no ‘superbugs’ in sewage escape into the environment.’

Chemicals

From News24, on March 29th 2023: Drug-resistant bacteria and poisoned fish: What is actually going on in Cape Town’s coastal waters?

https://www.news24.com/news24/southafrica/news/drug-resistant-bacteria-and-poisoned-fish-what-is-actually-going-on-in-cape-towns-coastal-waters-20230329

The above pictures show what a Marine Outfall looks like in the water… white plumes that are dispersed from the outlet pipes. Why white? The macerated toilet paper.

This is an idea of a marine outfall and the outlets of the pipe at the end. Not exactly the same as Camps Bay but it gives a good idea of how it works. Except Camps Bay, Hout Bay & Mouille Point are missing the “treatment plant” as they just use a straight pump. The diagram is similar to the pipeline between the tidal pool & Camps Bay beach which discharges the sulphur smelling flocculant from the water works on Kloof Nek

Solutions to the Problem

Our request to the City is to budget from the development projects and sewage levies for 3 treatment plants for each Marine Outfall. We are living in a time of innovation and development and we demand that our government take charge by allocating funds to end sewage pollution.

REMOVAL OF CHEMICALS OF EMERGING CONCERN FROM WASTE WATER by means of advanced water treatment processes typically used for drinking water production. This is also exactly what the city has commissioned at their massive Potsdam ‘water reuse’ project. (‘water reuse’ being a more politically-acceptable way of describing turning sewage effluent into drinking water)

Are Alternatives Affordable?

There are some ‘ball park figures’, for package treatment plants, and they were R150m for Camps Bay, R250m for Hout Bay and over R1 Billion for Green Point. This is in line with the city own estimates in ‘Marine Outfalls in Cape Town’, referenced in my example 7, which suggests treatment is R25million/ML.

The estimated capital cost for an advanced treatment process is R25 million/ ML per day of treated capacity. But is this affordable?

Estimates of sewage levy income for Camps Bay for 2015 were roughly R10m. Given the massive municipal increases following day zero, it’s safe to assume roughly R15m per year is collected by the city from Camps Bay alone today.

Multiply that by the 46 years that have passed since the new Camps Bay outfall was built, and that offers R690m. Where has that money gone?

Aren’t sewage levies collected and supposed to be spent on sewage treatment? R150m seems easily affordable, equivalent to ten years of levy collection. And worth remembering that improving the outfall won’t just help the Camps Bay residents who pay for it, but all the users of the beach, plus our marine environment. We believe similar calculations can be made for Hout Bay and Green Point.

Are Sewage Treatment Alternatives Desirable?

In the ‘hierarchy of needs’ from our city budget, that sewage treatment provision sits at the very top of such a spending hierarchy, above housing, roads, policing or electricity. Because most residents can choose to install solar for their electricity needs for example, they can choose a different road if a road is lacking, and many choose to build their own houses, not rely on council housing. And we have a national police service that can cover metro demands if need be. However, sewage treatment offers no such choices. We can’t choose whether to use a municipal sewage treatment plant, or direct our sewage elsewhere. So it is the most primary service commitment for any municipality, that affects every resident. Spending on sewage treatment, despite it not being very ‘politically-sexy’, should, along side the provision of water, thus be the highest priority. Besides the sewage levy argument, the city has a R120Billion infrastructure plan for the next 10 years, why are the MOP’s not included?:

According to the Urban Waste Water Treatment Directive for the EU, which came into force in 1991, all sewage has to be treated before discharging it into surface water. This spring the European Environment Agency (EEA) reported 96% Europe’s bathing waters met the minimum requirements set out under EU rules in 2016.

We propose that all new developments need to be fitted with their own domestic sewage portable treatment plants with some ideas that can be explored:

Please report your experiences to the direcorate for Community Services and Health as provided. When surfers, swimmers or beach-goers fall ill from suspected ocean pollution, the protocol is to alert the City’s Community Services and Health directorate. This log will assist us in our campaign as doctors do not report this. Reasons the City claims to have received no reports is because people either don’t make the report after they have fallen ill, or don’t make the report under the right directorate.

What the City can do:

By means of advanced water treatment processes typically used for drinking water production. This is also exactly what the city has commissioned at their massive Potsdam ‘water reuse’ project. (‘water reuse’ being a more politically-acceptable way of describing turning sewage effluent into drinking water).

https://www.water-reuse-europe.org/faure-new-water-scheme-identified-water-reuse-in-cape-town/#page-content

“The Faure New Water Scheme (FNWS) has been identified as the best opportunity for water reuse in the city of Cape Town, after 25 years of extensive research and planning. The scheme will receive treated wastewater from the Zandvliet Wastewater Treatment Plant, which is currently being upgraded to include enhanced treatment processes to ensure high quality of treated water. The treated wastewater from Zandvliet will be piped to the Faure Water Treatment Plant, 5 kilometres away for advanced purification. The Faure treatment plant is expected to produce up to 100 million litres of potable water per day.

In addition, all rivers & storm water outlet into the sea must have litter traps fitted to eliminate this issue, which should be checked regularly and serviced if broken.

What are the consequences of using marine outfalls to dump raw sewage in the ocean? ChatGPT provided the following summary.

Using marine outfalls to dump raw sewage in the ocean can have several environmental and public health consequences. While it was a common practice in the past, it is generally discouraged today due to the negative impacts it can have on marine ecosystems and human well-being. Here are some of the consequences:

Water Pollution: Dumping raw sewage into the ocean introduces a range of pollutants, including pathogens (bacteria, viruses), nutrients (nitrogen and phosphorus), suspended solids, and organic matter. These pollutants can contaminate coastal waters, affecting water quality and making it unsafe for swimming, fishing, and other recreational activities.

Health Risks: Raw sewage contains harmful microorganisms that can cause waterborne diseases in humans. Swimming or consuming seafood from waters contaminated with untreated sewage can lead to illnesses such as gastroenteritis, hepatitis, and respiratory infections.

Harm to Marine Life: The discharge of raw sewage can harm marine ecosystems. Excess nutrients from sewage can lead to eutrophication, a process where excessive plant and algae growth depletes oxygen levels in the water, leading to dead zones where marine life cannot survive. Pathogens in sewage can also harm aquatic animals and disrupt the balance of the ecosystem.

Loss of Biodiversity: Dumping raw sewage can negatively impact local marine species and biodiversity. Changes in water quality can lead to the decline or displacement of sensitive species, which can have ripple effects throughout the food web.

Coral Reef Damage: Coastal sewage discharge can contribute to coral reef degradation. Excessive nutrients can fuel the growth of algae that compete with corals for space, light, and nutrients, leading to reduced coral health and potentially causing coral bleaching and death.

Bioaccumulation: Toxins and contaminants in raw sewage can enter the food chain. Marine organisms can accumulate these pollutants over time, potentially posing risks to humans who consume seafood from contaminated waters.
Beach Closures: High levels of contamination from sewage outfalls can lead to frequent beach closures due to health hazards, which can have economic implications for coastal communities dependent on tourism.

Legal and Regulatory Consequences: Many countries and regions have laws and regulations that prohibit or restrict the dumping of raw sewage into the ocean. Violations can result in legal penalties and fines for responsible parties.

Public Awareness: The public perception of sewage dumping in the ocean can have reputational consequences for municipalities or industries involved. There is often public backlash and pressure to adopt more environmentally friendly sewage treatment practices.

To mitigate these consequences, many municipalities and organizations have invested in wastewater treatment facilities that treat sewage before it is discharged into the ocean. These facilities remove harmful pathogens and reduce the levels of nutrients and contaminants, improving water quality and reducing the negative impacts on marine ecosystems and public health. Proper sewage treatment and disposal are essential to protect the environment and human well-being.
