As recently as the late 19th century sewerage systems in some parts of the rapidly industrializing United Kingdom were so inadequate that water-borne diseases such as cholera and typhoid remained a risk. From as early as 1535 there were efforts to stop polluting the River Thames in London.
Beginning with an Act passed that year that was to prohibit the dumping of excrement into the river.
However, after the Great Stink of 1858, Parliament realised the urgency of the problem and resolved to create a modern sewerage system.Źródło: https://en.wikipedia.org/wiki/History_of_water_supply_and_sanitation

Used unskillfully, they can also damage plastic pipework and even copper tubing.
