Rainwater Harvesting is the practice of collecting rain via a large catchment area (typically a roof) and storing it in a tank for later use.
For every inch of rainfall, about 550 gallons of rainwater can be harvested for every 1,000 square feet of roof space.
In regions where rainfall is steady, it can become a major water source for self-sufficiency practitioners. Specialized filters and water pumps can be configured to turn rainwater into a potable water source.
Be sure to check with your state legislation on regulations or incentives that may apply. Read on to find out how you can turn rain into viable water source.
