I want to know the answer to the following question:
Who created Paris' reservoir system?
All the background I'm provided with is that "From 1857, the civil engineer Eugène Belgrand, under Napoleon III, oversaw the construction of a series of new aqueducts that brought water from locations all around the city to several reservoirs built atop the Capital's highest points of elevation.". Is that enough to answer the question?
Answer: yes
