Presentation at the Council of Water Managers Dinner Meeting on October 19th, 2010.

Over the last couple years, I have been fortunate to be living in Australia while designing and building one of the largest recycled water plants in the world. During my stay in Australia, I was also managing a design team out of Singapore which required me to make frequent trips to Singapore. Thus I was able to observe the water management policies and programs in these two countries. By bringing these ideas to you, my aim is to promote a healthy discussion on opportunities here in San Diego County.
