One kilometre of pipes, seventy valves, a filtration system that filters 360 cubic metres of water per hour. The reconstructed Hippo House in Prague Zoo hides a small factory. Thanks to the new filtration system we finally managed to have clean water. However, the reopening of the house was not the only celebration at Prague Zoo. The male Tchéco also debuted for the public.

“The Hippo House has reopened, and visitors can finally admire these remarkable mammals as they move underwater. Unfortunately, we had to do without a big opening ceremony to mark the end of the long and demanding reconstruction of the pools’ water treatment plant”, says Prague Zoo’s director Miroslav Bobek, “unfortunately, the last treatment plant was poorly designed, during the zoo’s previous management. It was as though they’d forgotten that a hippopotamus produces about 150 kilograms of faeces and urine a day, so there’s a difference between a pool system for hippos and one for humans.”

Semi-aquatic hippos move in the water mainly by means of their hind limbs. Thanks to their high specific mass, they can also walk on the bottom, which visitors to Prague Zoo can see with their own eyes in the new Hippo House.

Once again, visitors can watch not only the new male, Tchéco, but also the female, Maruška, and her offspring, Fanda, as they lark around in the water. At the moment, they live separately, however, in the future, Tchéco should become Maruška’s new partner. The new male hippopotamus came to Prague Zoo last November from the French safari park Plaisance-du-Touch. The French keepers named him Tchéco [cheko] in honour of the founding of our republic, because he was born on 28 October. That means he will be four years old this year.

The new water filtration system in the pools at Prague Zoo’s Hippo House is reminiscent of a small factory. A three-stage polluted water filtration system has been installed here. After removing coarse and fine impurities, the water is further purified using an ozonation system, a UV lamp and sand filters. They provide disinfection and break down substances that otherwise cause algae to grow and turn the water green (photos from the reconstruction).
