The commune lies in the Drainage basin of the Seine river and is, in large part, delimited by rivers.
To the west, it is delimited by the Vigny stream; to the east, by the Ru de Pontoise, and to the south the Oise river.
Other rivers that run through the commune are the Brouage and the Canal latéral à l'Oise.
The Canal de l'Oise a l'Aisne starts in the commune going south-east at right-angles from the Canal latéral.
