Keep Puget Sound Clean: Make it Hippo-Poo Free!


Woodland Park Zoo is asking the state legislature to help with its commitment to sustainability and resource management in the Puget Sound area. 

WPZ is requesting state capital funding for its priority sustainability project: reducing water waste from the hippo pool. With an approximately $2 million state investment, completion of the hippo pool project would save six million gallons of water annually—about 15 percent of the zoo’s total water use.  It would also reduce operating costs by $150,000 annually. 

Using sustainable filtration technologies such as constructed wetlands and on-site recirculation—green techniques that have proven to be a huge success with the zoo’s award-winning penguin exhibit—this project provides important public benefit by protecting the Puget Sound, directly reducing waste water impacts of nearly 10 million gallons per year. 

Take action now to support our sustainability efforts to keep the Puget Sound clean. Please sign the call to action letter below and we will deliver your signature to Capital Budget Chairs, Rep. Hans Dunshee and Sen. Jim Honeyford and their committees.

Thank you for taking action to support Woodland Park Zoo and protect the Puget Sound!
