Why you have to boil in the north of Würzburg too

The message came on Wednesday evening: Because of a find of enterococci during a routine check of the water supply in the Heiligenholz elevated tank on the Estenfeld district, drinking water from the Würzburg districts of Lengfeld, Lindleinsmühle, Versbach, Grombühl, Ober- and Unterdürrbach and the municipality of Estenfeld must be boiled.

But why do you have to boil water in Ober- and Unterdürrbach, for example, when enterococci are discovered in the Estenfeld district? Readers also asked themselves this in the comments on the article on mainpost.de. “Because the Estenfeld drinking water is also used to supply Würzburg with drinking water via the Grombühl 2 elevated tank, which supplies the northern supply area, “says Susanna Blum from the Würzburger Versorgungs- und Verkehrsbetriebe (WVV). An overview plan of exactly where to cook is available on the WVV website at www.wvv.de/trinkwasser.

“In our accredited drinking water laboratory, more than 20,000 samples are analyzed annually”

Blum can also answer the question of why the elevated tank is only examined once a month. The water values ​​in the affected elevated tank are checked once a month, she says. But in addition, the quality of the drinking water in Würzburg is measured every day at various points. “In our accredited drinking water laboratory, more than 20,000 samples are analyzed every year,” knows Blum.

The chlorination on the Sieboldshöhe could soon be stopped

For a few weeks now, the water in the supply area of ​​the water tower on the Siebolsdhöhe has also been chlorinated. Its supply area includes the areas of Gartenstadt Keesburg and the upper Frauenland. One reader thinks that the chlorination of drinking water has been going on there for too long.

Here, too, the chlorination is caused by bacteria. According to Blum, once the bacteria have been verified, the drinking water ordinance must be strictly followed. “Water samples are checked at various points over a longer period of time.” Only when these findings are negative for several weeks can the chlorination be stopped in consultation with the health department. The good news: If no more impurities can be found, the chlorination at the Sieboldshöhe will be stopped in the coming week.

The drinking water is chlorinated all year round in the waterworks in Mergentheimer Straße

According to WVV, the drinking water that is obtained in the waterworks in Mergentheimer Straße is also chlorinated all year round. After the treatment has been completed, a disinfectant is added to the drinking water purely as a precaution in order to avoid contamination in the pipeline system and the storage facilities. The addition takes place well below the maximum allowable amounts.

Therefore, a chlorine-like smell or taste can be perceived in the supply area of ​​the Galgenberg elevated tank, especially in Heidingsfeld, on the Heuchelhof and in the Sanderau, explains the WVV.
