. The Reppisch flows in the
Säuliamt (Affoltern district),
canton of Zürich, an area featuring still partially untouched nature.
Between
Birmensdorf and Dietikon, the river crosses a narrow valley which is used as a target range by the Swiss army troops stationed in the infantry barracks nearby. Therefore, this valley may be closed to entry during some parts of the week.
Shortly before entering Dietikon, the river underruns the Mutschellenpassstrasse and the
Bremgarten-Dietikon-Bahn railway. In the spring of 1999, there were heavy floods in this area, blocking the road and the railway service for several days.
Tributaries

Sixty eight named streams empty into the Reppisch, of which three, namely the
Wüeribach, the
Rummelbach and the
Lunnerenbach, are 4 or more kilometres long. In addition there are 5 tributaries that are 2 kilometres long or more: the
Dönibach, the
Lättenbach, the
Schwandenbach, the
Tobelbach near Birmensdorf and the
Malefizgraben, if one includes its right hand headstream, the ''Weidbach''.
The most important tributary of the Reppisch is the roughly 8-kilometre-long Wüeribach, which drains the plain of
Wettswil and
Bonstetten and empties into the Reppisch near Birmensdorf from the left.
