Actually, the new elevated tank on the "Schweiber" below St. Michael was supposed to go into operation this spring.

But the completion of the project, which is estimated at around two million euros, will be delayed by a few weeks.

One of the reasons: the incoming and outgoing lines had to be replanned.

Peißenberg

- Yes, it's a slightly larger Stadl.

Nevertheless, the new elevated tank looks relatively inconspicuous from the outside.

The dimensions of the future core of Peißenberg's drinking water supply only become really clear inside the timber construction.

There, two hygienically self-contained stainless steel tanks, eight meters high and designed with a diameter of 13 meters, were welded together.

An impressive picture for the layperson - but not only for the expert, but also for the specialist: "We were amazed at first," says Christoph Reichhart, a municipal utility worker.

And his boss, Georg Haser, agrees: "In reality, everything looks very different than on the plan.

Much bigger,” explains Peißenberg's water master.

The two stainless steel tanks, each with a capacity of 1100 cubic meters, will replace the old elevated tank from the 1970s.

Actually, the replacement should have already happened according to the original schedule.

But there have been delays.

There was a risk that the pipe would get stuck

So far, everything has gone smoothly on the construction of the elevated tank itself.

"We're on our last legs," reports Haser.

Only with the electronic components is there still a bit of a problem: "Because of Corona, the companies currently have hardly any people left," says Haser.

But that's not the main reason for the shifts in schedule.

The design for the new construction of the inlet and outlet lines caused major problems.

The existing piping of the old drinking water reservoir is being shut down because it is prone to breaks and other faults after more than 50 years of operation.

The plan was to drill a flushing bore on the slope above the western section of the St. Michelsweg up to the new elevated tank at the "Schweiber".

"That was the preferred option, because we wanted to keep the impact on nature to a minimum," explains Haser.

But the changing geological sections, some with massive layers of rock along the planned route, ruined the project.

"The resistance would have been too high and the tube would have been stuck," Haser states.

An open construction brought the desired solution

After examining other alternative methods, the municipal works ultimately decided to have the pipes laid up the slope using the cut-and-cover method.

There are three lines in total.

Namely the inlet from the drinking water well near the Böbinger Ammerbrücke, a bottom outlet pipe and the outlet into the Peißenberg drinking water network.

The open construction requires a high level of technical effort.

A walking excavator was requested by a specialist company from the Zillertal for the earthworks.

A swath in the forest could not be avoided, but will be reforested

Another downer is the interference with nature.

A path had to be cut into the wooded slope from the Michelsbach.

To protect the pipes, it will not be reforested after the construction work.

Laterally positioned tree planks should prevent the slope from slipping.

Haser is happy that the landowner played along: “He was absolutely understanding.

He immediately recognized the importance of the project.”

For Haser, the construction of the new elevated tank is a "stressful time".

But his employees get a lot of praise from their boss: "Without my team, nothing works.

That's perfect.” The new elevated tank is scheduled to go into operation at the end of June or beginning of July.

For Haser and his employees, things are a little more relaxed: "The new elevated tank will last around 100 years," says the water manager.
