Stand Alone Rainwater Harvesting System
Water the next oil?
Posted on May 14th, 2010

In investing circles, water is a hot topic. Some even say water is the next oil because as the population of the earth keeps growing, water will only become more precious because there is a finite amount that is fresh and within reach. T. Boone Pickens, the famous oil investor for example, believes so strongly in the economics of water that he has been buying water rights in Texas for resale at a later date. Many a movie (think Waterworld) has depicted a future in which fresh water is in extremely short supply.

In the water investing industry, much of the attention is focused on desalination on other technologies which increase the fresh water supply. Less attention is paid to recycling water and even more surprising is that rain water harvesting is mainly under the radar.

So what will it take to make rainwater harvesting a go to technology for increasing local water supply? RWH practitioners I've talked to all say that areas with water restrictions and high water prices are the early adopters. Yet in most other places the water itself is subsidized making the ROI on an RWH investment negligible. However, once these subsidies are removed and instead applied to RWH systems the overall result will be less consumption of municipal water and an increasing reliance on rain water. Many island nations have been operating this way for years and it is just a matter of time before the rest of us catch up.
