On CAPS, 98% of the 254 members who have rated Heckmann believe the stock will outperform the S&P 500 going forward. These bulls include MOTV8 and Tagit.

A couple of months ago, MOTV8 described Chairman and CEO Richard Heckmann in glowing terms: "Dude is a genius, all he does is build successful companies. Oil service play, AND a China play? Two for one."

Over the next five years, in fact, Heckmann is expected to grow its bottom line at a brisk rate of 27.5% annually. That's much faster than listed rivals such as Basic Energy (9%), Schlumberger (18.7%), and Veolia (13.1%).

CAPS member Tagit elaborates on the bull case:

Richard Heckmann is an extremely intelligent person and knows that treating the water used in the fracturing process that's environmentally "safe" is extremely important and profitable. While drilling for oil and gas is big business in these shale areas, having water that is treatable and can be reused is just as important. If not -- drilling comes to a stop.

It appears this company has the trump card in the energy sector when it comes to water treatment. The stock is relatively a safe bet and is one to hold for the next 5 years at least if not longer. ...

Bottom line. Natural gas and oil companies "small or large" need a water company and this one is about as good as they come. I'd suggest some serious due diligence and consideration for this stock.
