The Miracle of Modern Day Plumbing

Plumbing as we know it today - potable water delivery, waste removal, and heating and cooling - is unquestionably one of modern civilization’s greatest achievements.

Rudimentary plumbing has been discovered as far back as 2700 BC, where earthen pipes reinforced with asphalt were used in South Asia to transport water. Crete royalty were found to have had flushing toilets and running hot and cold water as early as 1700 BC. The ancient Romans are known for their public baths, aqueducts, lead piping, and wastewater removal systems, some of which are still in use today. In the 1,000 years that followed the fall of the Roman Empire, however, little to no progress was made. Waterborne diseases became increasingly prevalent people began living in closer proximity. In densely populated cities, people lived in squalid conditions, with little regard for waste disposal and water contamination.

When a series of worldwide cholera epidemics that raged in the 19th century led to the discovery in 1876 that the disease is caused by bacteria and spread through contaminated water, safe, segregated water supply and sewer systems were developed. Within decades, waterborne disease was nearly eradicated from the United States and average life expectancy increased dramatically thanks to the development of a clean water supply.
