On CAPS, 95% of the 182 members who have rated Insituform believe the stock will outperform the S&P 500 going forward. These bulls include rollotherichkid and fellow Fool Bryan Hinmon (TMF42).

A few months ago , rollotherichkid touched on the tailwinds working in Instituform's favor: "I think its time has come. As more cities suffer from shrinking budgets and failing sewer and water pipes this company will offer the best solution in price and quality."

Over the next five years, in fact, Instituform is expected to grow its bottom line at a solid rate of 18% annually. That's faster than more common construction and engineering plays like Fluor (NYSE: FLR) (11%), Jacobs Engineering (NYSE: JEC) (12%), and McDermott (NYSE: MDR) (11%).

Bryan offers three big reasons to buy into Instituform:

1. Reputation and scale. Insituform has rehabilitated more pipe than any other firm. The fact that it invented CIPP technology, has a large workforce that it can mobilize quickly, and has a 40 year track record give it a competitive advantage when bidding on rehab projects. Insituform wins nearly 50% of the contracts it bids on because of its cost advantages and reputation.

2. Focus on operations to complement growth. Insituform's current management team came aboard in 2008 and has instilled a culture focused on operational improvement. Since 2008, operating margins have improved to 9.5%, up from only 2.7%. ...

3. Great stewardship. New management is focused on profitable growth. In fact, they recently shuttered some European operations that didn't meet profitability hurdles and set a goal to achieve a 15% return on invested capital. ... And the board of directors recently instituted share ownership guidelines for all directors and senior management, so their interests are properly aligned.
