Saving H2O

A single hippo can generate about 22 pounds of waste per day. The Cincinnati Zoo has two.

hippo-infographic-webWith that much waste in a 70,000-gallon pool, it’s a challenge to keep the water clean enough for visitors to actually see the hippos. Thanks to a complex filtration system, and an enthusiastic school of poop-eating tilapia, visitors can see Bibi and Fiona through crystal clear water.

The zoo has saved 1 billion gallons of water since 2005 and 100% of the water put into the habitat comes from rainwater. A 400,000-gallon underground detention tank below Painted Dog Valley collects rainwater that’s filtered and used to feed the streams, waterfalls, and pools in Africa and other habitats.
