The Berglerner Gruppe water supply association is facing major challenges.
In the long term, a new waterworks will even have to be built at glass workers.
Thomas Spicker from the planning office Blasy-Overland carried out a system assessment of the water supply and presented the results at the meeting of the association assembly.

- He provided impressive figures: Well over three million euros will have to be invested in the long term.
The water supply in central areas lacks what experts call "redundancy".
That means: If part of the water treatment fails due to a technical defect, the emergency network with Moosburg, which has now been implemented, would have to step in.
According to Spicker, this cannot stay that way in the long term.
He stated that the entire water treatment is only "one-way".
A technical defect could result in a total failure of one week.
In his experience, an improvement here would require the construction of a new waterworks, for which the land would first have to be acquired.
The same applies to the storage tank into which the water from the well initially flows.
There is only one, and it needs to be refurbished in the medium term.
The system is out of date - Spicker: "You can't renovate the container, you can't clean it properly either."
The 60-year-old elevated tank near Wartenberg also needs medium-term concrete renovation.
After all: the water supply network is sufficient for the next 20 years.
However, the association urgently needs to think about what it intends to do with its network: the lines are getting on in years.
The association would actually have to renew 1.5 kilometers of water pipes annually to keep the network up to date.
With 150 kilometers of pipe length without the house connections, the issue will be.
Spicker warned: "Without a strategy we can get very hard!"
There will also be a need for investment in the medium term for the elevated tank in Scheidegg.
In addition to the emergency connection with Moosburg - “a difficult construction site” - a lot has happened: New pumps save 30 percent electricity.
A total of 300,000 euros was invested.
In the medium term, a further 1.7 million euros will be due.
"The other measures are still waiting for us," said the expert.
Actually, they wanted to be further: At the meeting it became public that the emergency connection with Buch am Erlbach had not yet been implemented - the cost allocation is still unclear.
The association provides 15,000 residents with 850,000 cubic meters of water annually over an area of 110 square kilometers.
