Book excerpt: Solving the world's water problems is proving to be one of the greatest investment opportunities of our time. Already, world water supplies are inadequate to meet demand, and the problem is going to get much worse in the years ahead. The World Bank estimates that 1.1 billion people lack access to safe drinking water and about 50 percent of the world's hospital beds are populated by people who have contracted water-borne diseases. If present consumption rates continue, in 25 years the world will be using 90 percent of all available freshwater. To address the problem, trillions of dollars will need to be invested in water infrastructure projects. And while the problems are most acute in developing and rapidly growing economies, there are huge water infrastructure needs in industrialized countries, as well. In the U.S. alone, it's estimated that more than $1 trillion will be needed for water and wastewater infrastructure projects. In Planet Water, water investment expert Steven Hoffmann explains the dynamics driving the water crisis and identifies investment opportunities in various sectors of the water industry. Hoffman provides investors with the knowledge and insights they need to make informed investments in water utilities, as well as companies providing water treatment services; infrastructure services; water monitoring and analytics; and desalination services. He also discusses mutual funds and ETFs that specialize in water stocks. Investing in the water industry is certainly no pie-in-the-sky idea. Over the past five years, many water stocks have exploded in value and water stocks as a whole have outperformed the S&P 500 by a substantial amount. In Planet Water, Hoffmann provides investors with everything they need to profit from this fast-growing industry in the years ahead.
