They have stated that there is no alternative to the pumping of millions of litres of effluent into the sea daily....

An 800mm pipe juts into the ocean 1.7km from the coast at Green Point. This pipe can spew up to 40 million litres of effluent into the sea at a depth of 28 metres - every day. Servicing the waste generated by the urban sprawl from Woodstock to Bantry Bay - via the City Bowl, the harbour, Green Point and Sea Point.

if the pipes around Cape Town are running at maximum capacity, 55 million litres of untreated effluent would pour into the ocean every single day. And by effluent, we don’t just mean sewage, but grey water. That means the water from your shower, your dishwasher, your sink, and your washing machine - everything that is flushed down plug holes, sinks, and drains.
Poop floating off Green Point last weekend by kayaker Karen Watkins. Photo: Karen Watkins Yes, the grey water dilutes the raw materials a bit. But poop is poop, untreated fecal matter direct from toilet to sea. Other elements are commonly found in grey water, such as paracetamol flushed out in urine (causes infertility in male mammals, including dolphins) or even oestrogen flushed out in the urine of women on the pill. Oestrogen released into rivers in the UK has resulted in fish being feminized - changing sex from male to female.
