On CAPS, 99% of the 120 All-Star members who have rated Energy Recovery believe the stock will outperform the S&P 500 going forward. These bulls include Seansonfire and TMFBreakerThiel, both of whom are ranked in the top 5% of our community.

Just last month, Seansonfire singled out the stock as a nice pick for growth-thirsty investors: "Great growth potential, good balance sheet, great strategic moves as of late. ... If you believe as I do, that Water Scarcity will be a major issue facing the world over the next 25 years, you need to invest in this stock."

In an earlier pitch, TMFBreakerThiel also urged Fools to ride the fresh water wave:

This is first and foremost a bullish call on the growth of desalination projects around the globe, which I think is a very safe source of growth over the coming decade. But Energy Recovery also has a great business on best-in-class energy recovery devices for desalination plants, and will grow both with new installations and retrofits.
