Source of Water in Oldenzaal, The Netherlands

Tap water in Oldenzaal comes from groundwater drawn from aquifers beneath the Twente region in Overijssel. Vitens, the regional drinking-water company, extracts and treats this groundwater before sending it through the local distribution network.

The groundwater is naturally filtered through layers of soil and sand, then purified and tested to meet Dutch drinking-water standards. It is not supplied from a surface-water reservoir or directly from the nearby Dinkel River.
