Who Built the Sewers of Paris?

By Anna Duncan

Paris, the City of Light, is known for its picturesque architecture, stunning monuments, and romantic atmosphere. But what lies beneath the charming streets of Paris is equally fascinating – a complex network of sewers that have been instrumental in keeping the city clean and hygienic for over a century.

Have you ever wondered who built these remarkable sewers? Let’s explore the history of Parisian sewer system and the people behind it.

Origins of Parisian Sewers

The first signs of a sewage system in Paris date back to the 13th century when open-air gutters were constructed to carry wastewater away from homes and streets. However, it wasn’t until the 19th century that a comprehensive sewer system was developed to address the growing sanitation problems in the city.

The Visionary Engineer: Eugene Belgrand

The man responsible for designing and building the modern sewer system in Paris was Eugene Belgrand. Born in 1810 in Creil, France, Belgrand was a brilliant engineer who dedicated his life to improving public health by revolutionizing city infrastructure.

Belgrand was appointed as chief engineer of Paris’ waterworks in 1869. His first task was to create an efficient sewage system that would prevent contamination of drinking water sources and improve public health conditions. Belgrand’s vision was to build an underground network of pipes that would transport wastewater away from residential areas and into treatment plants located outside the city.

The Construction Process

Belgrand’s plan required extensive excavation work as well as innovative engineering designs to ensure proper flow and filtration of wastewater. The construction work began in 1878 and took almost two decades to complete.

The project involved laying approximately 600 kilometers (370 miles) of pipes beneath the streets of Paris, with some sections reaching depths of over 20 meters (65 feet). The pipes were made from durable materials such as brick, stone, and concrete to withstand the weight of the city above.

The Impact of Parisian Sewers

The completion of the sewer system had a significant impact on public health in Paris. The city’s residents were no longer exposed to the foul smell of open-air gutters and contaminated water sources. The risk of waterborne diseases such as cholera and typhoid fever was greatly reduced, leading to a decline in mortality rates.

Belgrand’s innovative design also paved the way for modern sewage systems around the world. His use of gravity flow and filtration techniques set a new standard for efficient wastewater management that is still used today.

Conclusion

In conclusion, Eugene Belgrand was the visionary engineer behind Paris’ remarkable sewer system. His dedication to improving public health through innovative infrastructure designs has left a lasting impact on the city and the world. Next time you stroll along the charming streets of Paris, take a moment to appreciate what lies beneath your feet – a testament to human ingenuity and perseverance.
