People have been collecting rainwater for thousands of years for several reasons. It provides people water to use again in their gardens, helps control stormwater runoff, reduces erosion risks and helps mitigate the threat of flooding to name a few.

Harvesting rainwater can be beneficial in a variety of ways. It can help individuals save money on their water bills and it can also help communities as a whole to cut costs. It is also great to have an alternative source of water if for some reason your area’s water did become contaminated.

Harvested rainwater can also give your plants and garden an extra boost. It is typically free from several types of pollutants, chlorine, and other man-made contaminants.

However, in today’s society collecting rainwater is not completely legal in all states and there are various restrictions and regulations that you should be aware of depending where you reside. When the government forms legislation regarding rainwater collection they consider factors such as water rights, quality standards, and public health. However, in recent years droughts and population changes have pushed for more progressive changes to be made.
