For the exhibit residents, hippos Button and Genny, the redesign of their life support system and oxygenation tank was essential. With the help of animal life support experts, DCM designed and installed new energy efficient water pumps and equipment to keep their water clean and clear. DCM also transformed the Hippo Haven exhibit into more of an experience. The final design tells the story of the Nile River through new lighting that simulates the different times of the day. Projected images along the wall immerse visitors into the hippos’ natural habitat. Visitors can now enjoy watching these 3,000-pound creatures frolic in their pristine 60,000-gallon tank.
