Water harvesting, the collection of rainfall and run off for future use, has been practiced for thousands of years; but in some
lina2011 [118]

Rainwater is normally free from dangerous substances, which makes it perfect for irrigation schemes. Added significant benefit is that it decreases the requirement for fresh water. It is important particularly in regions with low water levels.

Another benefit might water harvesting have in these areas with land erosion due to runoff are as follows;

Reduces Water Shortages

In temperate areas, the strain on public water supply can become hard, even in advanced countries. Rainwater decreases the uncertainty of water shortages. Using rainwater for non-essential actions such as spraying the lawn means less pressure on the supply of safe drinking water.

Replenishes Groundwater

Extensive rainwater harvesting projects with the water collected into storage containers or tanks are important to assure a sustainable groundwater level.

Reduces soil erosion

Heavy rainfall generates erosion because some of the soil is transferred along with the passage of water. Soil erosion exhausts agricultural land of topsoil and nutrients, provides to sediment build up in waterways and, in advanced cases, can turn land inadequate for agriculture. Harvesting rain checks a great chance of soil erosion before it can originate.
