Currently, Mueller even trades at a PEG (0.8) discount to close rival Tyco (1.1), as well as other water plays like Aqua America (NYSE: WTR) (3.2), California Water (NYSE: CWT) (4.2), and Veolia Environnement (NYSE: VE) (2.1).

CAPS All-Star rws1773 dives deeper into the bull case:

Growing population and an aging infrastructure = huge potential profits for [Mueller]. Many municipalities continue to be reliant on parts of their water distribution infrastructures that in some cases are over 100 years old. Upgrades and increased efficiencies in our water distribution systems are required throughout the country to wring the last drop possible out of our water sources. Fresh, clean water will become an even more precious resource in the future, eventually surpassing oil as the liquid investment of choice. Companies such as [Mueller] will be able to capitalize on the increased demand as new treatment and distribution plants are built and existing infrastructure receives long overdue upgrades.
