Oberhausen Water Tower, Industrial water tower in Oberhausen, Germany.

The Oberhausen Water Tower is a roughly 50-metre-high tower at Mülheimer Straße 1, built in 1897 by the Gutehoffnungshütte. Its round shaft of brick masonry carries an Intze-type elevated tank holding 1000 m³, fed by three pressure mains. Since 13 March 1985 it has been a protected monument, now used by a surveying office as living and working space.

The tower was built in 1897 to supply water to the rapidly expanding industries of the Ruhr region. It was decommissioned in 1965 when more modern water supply systems replaced its function.

The tower's name comes from the Gutehoffnungshütte (GHH), the Montan company that built it in 1897 to replace its demolished water towers on Obere Marktstraße. Since 13 March 1985 it has been a protected monument, and today a surveying office uses it as living and working space.

The tower stands at Mülheimer Straße 1 in Oberhausen, a brick shaft with an Intze tank of 1000 m³ on top. It is not open as a museum: since decommissioning it has been used by a surveying office as living and working space, so the interior is not visitable. View it from the street.

The tower's tank is an Intze-type reservoir holding 1,000 m³, a design named after engineer Otto Intze. It sits on a round shaft of brick masonry, and since 1985 the structure has been protected as a monument; a surveying office now uses it as living and working space.
