Binzaweiher with Schwalbenhotel
In the spring of 1993, the Binza rainwater retention pond for the municipality of Mauren and the city of Feldkirch was completed. At the same time, the border ditch was expanded from the pond to the ash.
Half of the pond is on Liechtenstein and half on Austrian territory.
The relief water from the sewer system of Mauren and the rainwater from the hub is relieved in the "Binza" in the border ditch. A rainwater retention pond is to be built in order to break the large flow peaks and to hold back pollutants.
The municipality of Mauren and the city of Feldkirch each take on half the construction of the Binza retaining pond and the expansion of border trench 2 from the Binza retaining pond to the Esche (platform ditch).
The retention and settling pond covers an area of 6,666m2. With it, a usable retention volume of approx. 2,200m3 can be achieved. The water level shows a difference of 70cm between still water and maximum water level.
The state border between Liechtenstein and Austria runs right through the pond.
In addition to the advantages for the water balance, the retention and settling pond will also provide a valuable link for landscape design and will also be of major importance as a biotope adapted to the reed.
Swallow Hotel
In 2010, a swallow house with 40 nests was built on the east side of the Binza pond at the suggestion of the Mauren Ornithological Association. Zimmerman Franz Senti built this "swallow hotel" according to the plans of the German Nature Conservation Union and an example of the Liechtenstein Ornithological Association.
