Insufficient water quality

The quality of the water is insufficient.

The presence of certain snails and bird species in (swimming) ponds ensures that, in times of warmer periods, the carried parasite Trichobilharzia swimmer's jaw spread. In some cases there are no snails to be found, but the parasite is present in the water. The parasite causes itchy inflammatory reactions on the skin, headache and fever in swimmers.


Cercariën barrier

The Cercariën barrier is a floating line with a rubber screen. This closes the (expected) propagation area of the snails that carry the Trichobilharzia parasite, and can not spread further in the lake. In this way, the swimmer's kidney is greatly reduced.

  • Only needs to be build once.
  • Can be implemented if the parasite is suspected.
