Dorsten-Holsterhausen waterworks

The Dorsten-Holsterhausen waterworks is located in North Rhine-Westphalia in the northern Ruhr area in Dorsten - Holsterhausen about 300 m northwest of the Lippe . The operator of the waterworks is the RWW Rheinisch-Westfälische Wasserwerkgesellschaft .

After test drilling between Dorsten and Schermbeck , only the Holsterhausen gallery with 47 fountains along the Lippe went into operation in 1927; in 1974 the fountains in the Üfter Mark were added. The 185 km² catchment area of ​​the wells has been designated as the Holsterhausen / Üfter Mark water protection area since August 1998 . This makes it the largest drinking water protection area for a groundwater resource in North Rhine-Westphalia. Since 1992 there has been a voluntary cooperation agreement between the operator of the waterworks and the local agriculture with the aim of a water-friendly land management. Around 360 farmers and almost 40 gardeners are now working with RWW. Through its operator RWW, the waterworks also belongs to the AWHS - Arbeitsgemeinschaft Wasserwerke Halterner Sande , in which the municipal utilities Borken, Coesfeld, Dülmen and Gescher as well as Gelsenwasser AG also participate. The aim of the working group is better cooperation with each other, with the state environmental authorities and with agriculture.

Today's total of 64 wells deliver natural groundwater from the "Haltern Sands" and the "Recklinghausen Marl", Cretaceous deposits from the edge of a subtropical sea, from a depth of 80 to 100 meters with a water extraction capacity of 29 million cubic meters per year. At these depths, the groundwater is free of human-made contamination and only needs to be de-iced before it is fed into the drinking water network. Alongside the Reken-Melchenberg and Velen-Tannenbültenberg waterworks, it is one of RWW's three groundwater works. From 1991 to 1993 the waterworks were extensively modernized, including a new de-iron and filter system was put into operation. Like all other RWW works, the waterworks is monitored and controlled by Mülheim-Styrum / Ost.

Parts of the cities of Gladbeck , Oberhausen , Bottrop , Dorsten and the communities of Schermbeck and Raesfeld - Erle are supplied with drinking water, a total of around 350,000 people.

The waterworks is part of the route of industrial culture, themed route industrial culture on the Lippe and can be visited as part of excursions.

Another RWW waterworks is located at the Blue Lake in Dorsten. From this artificially created reservoir fed by two streams (Hammbach and Wienbach), up to 17 million m³ of surface water can be extracted annually, which is then given to the power plant industry as process water without treatment.
