Technology and Plumbing

By Tal Potishman

In present times most residents of the United Kingdom take properly working plumbing systems for granted. Most do not take the time to think about the history of plumbing or the way plumbing technology has evolved over time. Plumbing has a long and interesting history: a history that is worth exploring.

It was during the Greek and Roman empires that plumbing technology first started to evolve. Basic plumbing systems were invented and installed during these empires' rule to make it easier to carry water to and from the public bathing houses that were so popular. It was this necessity that lead to the invention of the aqueduct during the Roman Empire. The aqueduct was the primary mode of plumbing and water distribution from the Roman Empire until the 1800s.

Pipes were constructed mostly from lead during ancient times and aqueducts were pieced together from stone and clay. However, this is no longer the case in modern times. Today, steel, brass, copper and plastic are the most popular building materials for plumbing and piping systems. Lead is no longer used to make pipes because the toxicity of lead is considered to be too high.

The bath houses that the Romans enjoyed are considered the predecessors of plumbing as it currently exists. Originally, public bathing only occurred while the sun was up because the bath water was only replaced once each day. Remember, it was not until long after the Roman Empire fell that bacterium was discovered and the western world learned how diseases were spread with the obvious implications on bathing and personal hygiene. In Roman times, one water change each day was all they thought they needed.

Perhaps more important than the public baths and aqueducts, though, is the evolution of the modern toilet. The toilet that is so familiar to the modern western world was first invented around 2800 BC in Mohenjo-Darco and was made from a seat placed upon a pile of bricks. In those times only the highest class of society was allowed to use the toilet. It was not until the middle of the nineteenth century that the western world adopted the sit-down toilet that was popular with the ancient Romans.

As the western world adopted the plumbing and toilet structures that were invented in Roman times the technology surrounding the systems exploded in volume and size. In less than one hundred years the western world helped toilets and plumbing fixtures advance from aqueducts and sit down holes to the sophisticated and technically complex modern marvels that western people now take for granted.

In today's plumbing systems most pipes are kept under the ground and cesspools and open sewage drains have almost been completely eliminated due to environmental and operational considerations. As the western world continues to advance it is highly likely that plumbing and toilet systems will become cleaner and more efficient as well, with further introduction of green technology and improvement in treatment of sewage and contaminated water. - 30517
