Water Recirculation at Sac Zoo
Channel: Cal OES
Date: 2014-08-29

The Sacramento Zoo also conserves water by recirculating their water through a filtering system. 

The Lake exhibit uses a filter system so that it does not have to be drained and cleaned as often as it would without the filtration. Currently, the lake is drained once a year. 

The North American River Otters also get to splish-splash in their cool pool with water that gets filtered and cleaned every other week instead of everyday! Now, that's a big conservation effort!
