1. Reduces Flooding and ErosionHarvesting rainwatercan help the environment in a number of ways. For starters, it can reduce erosion around downspouts and in gardens. It can also control storm water run-off. Rainwater doesn’t produce scale and corrosion as hard water does. The collection of rainwater may reduce flooding in certain areas as well.

2. Reduces Water BillsRainwater harvesting will not only help individuals save on their water bills but can cut costs for entire communities. The cost to supply mains and overall water services can be substantially reduced when many people in one community use rainwater. Having a source of water can also reduce dependence on municipal sources in case the water becomes contaminated. Rainwater can be used as the primary source of water or as a backup source when needed.

3. Reduces Demand on Ground WaterSources of ground water are increasingly being strained in many areas throughout the world. Digging deeper wells is not only expensive but can cause environmental damage such as collapsing the soil where the water used to be. It only makes sense to use sources of rainwater whenever possible.Harvested rainwatercan be stored and then used during times of drought and when the ground water supplies have been depleted.

4. Can Be Used for Non-drinking PurposesThe majority of the water we need is used for non-drinking. Everything from washing clothes and dishes to bathing and flushing toilets require large amounts of water. Rainwater can be used for all of these things. Rainwater is soft and can lessen the need for detergents when washing clothes and dishes. Rainwater can also be used for washing vehicles, bathing pets, and nearly all cleaning that uses water.
