The water investment theme can be played with exchange traded funds on a domestic or global  level.

“As the world population increases, so does the demand for clean water. Global water consumption has increased nearly twice as fast as population growth in recent years. United Nations projections place global population growth at 30% by 2030, and as demand continues to grow accordingly, some projections place the water industry at a trillion-dollar market cap as early as 2020,” Abraham Bailin for Morningstar wrote in a recent analysis.

PowerShares Water Resources (NYSEArca: PHO) tracks an index of industrial firms dealing primarily in the water space: water treatment, water utilities, pipe and pump manufacturing, and so on. This ETF does one of the better jobs in generating most revenue from the water industry, reports Bailin. [Water ETFs Soak Up Optimistic Industry Growth Forecasts]

Additionally, water infrastructure spending is hovering around $80 billion per year, and is most likely to double over the next few years, according to the World Water Council. The infrastructure investment theme is evident in developed nations, as the old systems in place must be upgraded and in fresh water-scarce emerging nations where systems have yet to be implemented, reports Eric Dutram for Zack’s.

Ultimately, water is becoming more limited on a global level, and about 3% of the water supply on Earth is fresh water. As the supply gets smaller and populations keep expanding, the need for potable water is evident. Companies and governments must come up with ideas to recycle, manage and desalinate water in the near future.
