Rainwater harvesting pays off

Whether a rainwater harvesting system is economically viable depends on many factors. These include precipitation patterns, the available catchment areas, drinking water and wastewater prices, whether the system is new or retrofitted, what the rainwater is used for, and much more. If you can retrofit a simple rainwater system for garden use yourself, such an investment can quickly pay for itself. For irrigation, only rainwater should be used anyway because of the low salt content. Often, however, it is also a matter of enabling a certain independence and security of supply for the future with one's own rainwater harvesting system. In remote areas, rainwater is sometimes even the only source of water.
