The Średzka Woda (Średzianka, German: Neumarkter Wasser) is a second-order river in the Lower Silesia province of Poland, a left-bank tributary of the Oder.

[1][2] The river flows out of Piersno, Środa Śląska County, on Sredzka Upland, at 158 m above the sea level.

Further on, it turns north again and bypasses Chwalimierz, then flows through Środa Śląska, where it crosses the national road no.

The left one bypasses Szczepanów from the west, which is the result of land reclamation currently taking over the major part of the flow of the Średzka Woda River.

In this place the river leaves the vast Upland and, through the reclamation channel, it flows along the Oder Valley.
