Tap water carafe

An ode to Dutch tap water


The Tap Water Carafe is a water carafe designed to promote the use of tap water. Dutch tap water is top quality drinking water and it is 2000 times cheaper than bottled water. More importantly, it requires no environmentally polluting plastic bottles or transportation. The stopper of the carafe clearly refers to where the contents are tapped: from the tap, of course!

Oer Tile

From sludge to tile


The Oer tile is an earthenware tile colored with iron sludge. Iron sludge is a natural residual material of the production process of tap water, which we obtain directly from the water production company in Eindhoven. We transform the iron sludge into a pigment by drying, grinding and sieving the material several times. This process results in the Oer tile which is available in series of tiles in different shades of pink.

Oer Tableware

From sludge to tableware


In this tableware collection primal, refined and functional forms and materials relate to one of the most important resources of this planet; water. The iron sludge that is used in the clay, engobes and glazes represent the production process of potable water. Thereby this tableware brings us closer to something we often take for granted.

Drinking water passport

The identity of our drinking water


Drinking water in the Netherlands is extracted from various sources. That is why every drop of water that comes out of the tap is unique. You can say that water has its own identity.  Lotte de Raadt works together with drinking water supplier Brabant Water on a drinking water passport for the various sources in Brabant.
