The article reflects on the sweltering summer of 1858 in England, where Members of Parliament staggered through the Palace of Westminster, overwhelmed by the foul smell emanating from the River Thames. This 'Great Stink' was a result of London’s untreated sewage being dumped directly into the river, creating a public health crisis that demanded immediate political action. In response to this crisis, the House of Commons quickly authorized the construction of a modern sewage system, designed by engineer Joseph Bazalgette, which was the largest and most advanced of its kind at the time.

The piece also draws a parallel to the present-day challenges faced by Osaka, Japan, as they grapple with their own wastewater problems. The author suggests that Osaka may be entering a 'Golden Age' of sewage management, similar to what London achieved in the late 19th century. This emphasis on wastewater infrastructure reflects global concerns regarding public health and the environment, underscoring the importance of modern sewage systems in urban management.

Overall, the article highlights how historical experiences with public health crises can still resonate today, as cities like Osaka look to improve their infrastructure. By learning from past mistakes, modern cities can implement effective solutions that not only improve sanitation but also enhance the quality of urban life for their residents.
