Studio Octopi has designed concepts for swimming pools in the River Thames
The idea is in response to 'London As It Could Be Now,' an open call ideas project
The idea was inspired by Thames Water's plans to create the Thames Tideway Tunnel 'Super Sewer'
The Thames Tideway Tunnel would reduce sewage in the River Thames by 96 percent
If it receives planning approval, the Thames Tideway Tunnel would be due for completion in 2023
