The United States' Aging Water Infrastructure

Thecurrent crisis in Flint, Michigan- where lead from the city's aging pipe system has leachedinto the watersupply - has drawn national attention to the nation's aging water infrastructure.

Bysome estimates, more than $1 trillion in upgrades over the next 25 years are needed to the vast system of mostly underground pipes in the U.S., and experts are saying concerns over the aging infrastructure can no longer be ignored. In fact, TheASCEbelieves that most of our drinking water infrastructure is nearing the end of its useful life and gave the country's drinking water and sewage infrastructure a "D" grade.

Without upgrades, the U.S. economy is expected to shrink by $416 billion due to increased costs to households, loss of worker productivity, and increased wasting of water... and more events like Flint, Michigan. Other developed countries are facing a similar situation.

What kind of investments does the country need?

New and improved treatment plants, expanded pipes, and better waste-water networks.

The ASCE recommends financing these projects through government loans, private bonds, and through the establishment of a federal water infrastructure trust fund.

Additionally, bills are in process in various state capitals that could open the door to the privatization of water utilitiesin an effort toimprove thequality and operations of poorly managed public water systems(like the one in Flint). In a privatization, the states that own their own water utility companies would sell those companies to private investors.

Investing in Water Infrastructure Companies

One way to benefit from these coming changes is to invest in the stocks of individual water utility companies. There are many small water utility companies, and further privatization could lead larger companies to buy them out, which would make those companies stronger while making more money available for infrastructure development.

The implementation of this strategy is already partly underway. American Water Works Company (NYSE: AWK), the largest publicly traded water and waste service provider in the U.S., bought 13 smaller utilities in 2014, and the second largest utility, Aqua America (NYSE: WTR), has bought 300 utilities over the past two decades.

Other potential investments include the stocks of companies that actually build water infrastructure and equipment, such as:

  • Calgon Carbon (CCC): Amanufacturer ofproducts that remove contaminants and odors from liquids and gases, both for industrial, municipal, and consumer markets.
  • Mueller Water Products (MWA): One of the largest manufacturers and distributors of fire hydrants, pipe fittings and valves in North America.
  • Xylem (XYL):A manufacturer ofpumps, valves and analytic equipment used to move, test, and treat water in more than 150 countries.

There are a tonof different individual water companies to research, and a lot to learn about how the industry works.

You don't have to worry though. That's why God created index funds.
