Since the opening of the hut in 1908 the waste water was
eliminated through a three-chamber-foul-pit. Eventually the
responsible water-office objected to this procedure. A connection
to the local waste water channel system of Benediktbeuern had not
been possible because of the 12km distance in the alpine
environment. So other ways to a solution had to be found.
Requirements have been: Process engineering as simple as possible,
no requirement of energy (gravity principle), high biological
effectivity, sufficient capacity even with many visitors and an
acceptable integration into the alpine landscape. The solution had
not to overcharge the financial and physical power of the Sektion
Tutzing.
With the new system waste stuff will be cleared by a fat-eliminator
first, then pre-purification is done through two rock-caverns with
24 cubicmeter content, post-purification through two further
caverns. Finally there follow three post-purification lakes with
about 800 squaremeters surface. They have been nicely integrated
into the alpine environment and show green meadows and plants
around.
This system guarantees the compliance with the strong german
DIN-Norms for waste water elimination. How good this system works
is shown by fishes and frogs in the lakes. Especially the fact that
there are fishes proofs the good quality of the water. (We think
that some wild ducks have brought the fish-eggs (rogen) with their
feathers from rivers down in the valley)
So the alpine purification system guarantees that the waste water
of the hut does not pollute the environment. An electric fence
around keeps the cattle away. The contents of the purification
caverns once a year will be pumped into a drying-chamber and there
stored for the transport down to the valley. The complete system
needs no energy with the exception of this onetimes yearly
pumping.
Who at all thinks after having had good food and drinks and then
use public hygiene about all the efforts the Sektion Tutzing had
until this high standard of pollution control had been
reached?
Thank the Sektion Tutzing for their engagement on pollution control
by visiting the hut Tutzinger Hütte!
