Until the Middle Ages, the drinking water in Paris was taken from the River Seine. The wastewater was poured onto fields or unpaved streets, and finally filtered back into the Seine. Around 1200, Phillipe Auguste had the Parisian streets paved, incorporating a drain for wastewater in their middle. In 1370 Hugues Aubriot, a Parisian provost had a vaulted, stone-walled sewer built in the "rue Montmartre". This sewer collected the wastewater and took it to the "Menilmontant brook". However, the wastewater was still drained in the open air.
