There is no plan from the bierhauslerquelle in geroda. It lies on the edge of a path in the forest area of seiferts-eller. It has been gushing since 1902 and supplies the town with drinking water. At the suggestion of the health department of bad kissingen, the local council would like to explore the source with a camera at the beginning of the week.
"We liked to examine the stock", explains heike kraus. The hydrogeologist from the baur consult office in habfurt is currently frequently on the road in the region. In addition to geroda, it also accompanies the rehabilitation of the springs in motten and the drilling of the new well in the neighboring community of schondra. The bierhausler spring, she says, has not been structurally altered in 115 years. Only on the land have ditches been dug, earth has been filled in and a small house has been built above the spring shaft.
Camera stops after one meter
the experts from aqua brunnen service regenerierungstechnik gmbh from eltmann place a camera in the pipe from which the water is gushing. Remote-controlled, it drives against the water flow, which pushes out of the pipe at a rate of about 6 to 6.5 liters per second. The first images appear on the screen, but after just under a meter, the camera stops for the time being. The pipe is interrupted by a gap. "A "settling shaft", suspects water manager werner schneider.
Now a smaller camera is fetched, which is pushed over the settling shaft with sticks. The pipe then continues for another ten meters or so until it reaches a wall through which the water enters the pipe. Mayor alexander schneider (UWG) reports that the experts assume that there are two seepage lines. A few roots were visible, but "nothing dramatic", says schneider.
Condition of the spring is good
"the pipes are free. We can't get any more out of the spring", the burgermeister sums up the result of the investigation. Initially, the council had suspected that roots could be obstructing the water supply. But even after 115 years, the spring is still in good condition.
Nevertheless, in the long term, the council will have to think about a second pillar of the water supply. The bierhausler spring supplies geroda with water and fills the high reservoir. From there the water is pumped into the reservoir at platz. There are springs in platz, too "but they've been out of action for years", explains heike kraus. With a blind eye, the water was clear, but turbidity and microbiological changes were measured again and again.
Second pillar sought
matthias kleinhenz from the public health department reports that the rate of groundwater recharge is declining throughout lower franconia. The debris of a spring always changes – for example, depending on the season. The dry winter has also had an impact on the spring in geroda. The debris flow remained two to three liters per second below the average value. In euerdorf, the spring has recently dried up completely. In the meantime, however, the water is bubbling again, says kleinhenz.
With the inventory of the spring, the municipal council now has a basis for making further decisions. But there is no urgent need for action, says mayor schneider. 10,000 euros have been earmarked in the budget for the investigation. 20,000 euros have been set aside for possible repair work. The investigation of the source has nothing to do with the microbiological contamination in the drinking water network a few weeks ago. Schneider reports that at the time, the heavy rain had caused water to enter the pipeline system.
