"For those in search of a pure play in the water infrastructure sector, my favorite bet is Insituform (NSDQ: INSU)," says Roger Conrad in his newly-launched advisory service, The New World.

Conrad explains, "Its most innovative product is its fast-growing 'trenchless' repair service to aging and cracked pipes." Here's his review.

"Rather than dig up and replace actual pipes, the process involves injecting a compound into the pipe itself which acts to seal any breaches. The result is a lower cost and far less intrusive repair.

"Insituform has languished in recent years, as overly aggressive expansion by prior management ran up against a brick wall of stagnant to falling system investment by municipalities.
