Which action did Chadwick recommend to improve public health and reduce taxes?

Chadwick's recommendation to improve public health and reduce taxes focused on the improvement of drainage and sewer systems. In his 1842 report on the sanitary conditions of the labouring population in Great Britain, he emphasized that inadequate infrastructure, particularly in sewerage, was a significant contributor to poor health and disease. By advocating for better drainage and sewer systems, Chadwick believed that it would lead to a reduction in illness and, consequently, lower healthcare costs for local authorities. This improvement in public health would not only benefit the population but would also alleviate the burden on public spending by minimizing health-related expenditures. Effective drainage systems would help prevent outbreaks of diseases like cholera and typhoid, which were linked to contaminated water sources, thereby fostering a healthier community and justifying the financial appeal of such investments.
