Through harvesting those rainfall inches falling from the sky for human and animal consumption, water bills are reduced as well as costs for distribution. New rainfall catchment systems provide valuable reserves during times of drought and saves land that would otherwise have to be used for reservoirs. This can be extremely important in parts of the world where rain is scarce or where over-population occurs. By harvesting rainwater, any area can reduce costs and the strain on natural resources.

Rain water collection can still be advantageous to gardeners living in areas where water collection isn’t really necessary because the rainfall average in their area is an adequate amount. Even in those locations, there is generally a few times a year when a short term drought occurs and supplemental irrigation from the spigot becomes necessary to keep gardens from submitting to the elements. While this type of water supplementation helps to keep the plants alive, it is not until enough rainfall inches have fallen that vegetation really perks up with renewed vibrancy.

A closely related process to rainwater harvesting is groundwater recycling. These systems also recycle new rainfall, but in a way that it is concentrated in a single area, like where crops and plants are to be grown. This is also referred to as groundwater harvesting and is common where wells only provide enough water for people and animals, but are generally strained to meet the needs of crops or gardens. Groundwater recharging is the term used for changing groundwater into a drinkable form, and it is very common in areas that receive daily water in rainy seasons.

It is true that rainwater harvested from roofs can contain impurities directly related to the roof itself. Additionally, there are instances where collected rain water contains pesticides and other contaminants. Since this is the case, many times the water in rainwater containers or tanks must be purified before it can be used as drinking water. This can be done through filtering, boiling or through the use of additives like chlorine. The purification of rainwater can also be done even earlier in the process by placing filters in the tubing that directs the water into the storage tanks.

Rain harvesting systems are inexpensive and can be built into structures so that they are barely visible, yet always catching those precious rainfall inches. Rainwater containers or tanks can be buried in the ground or placed in a basement, invisible but highly useful. Rooftop systems can be made so that they are virtually invisible from the ground. Look into rainwater harvesting as a way to save you money, to help reduce your impact on the environment and to bring a stream of fresh water to you each day.
