Rainwater harvesting techniques! Comprehensive Solution

What is rainwater harvesting?

Rain water harvesting is a method of causing the collection, storage and preserving rainwater runoff from agriculture in semi-arid and dry climates. This is known as rainwater harvesting. This article will examine the rainwater harvesting techniques and different types of rain water harvesting.

Harvesting rainwater can be used for agricultural purposes. It is utilized to water the crops of agricultural fields and in gardens in residential areas. In addition, they save gardeners and farmers money by reducing their dependence on other water sources.

Types of rainwater harvesting

Butt of Water

Uses of rainwater harvesting device is simple; water Butt collects rain water that falls from natural downpours or drain pipes and stores it in a container. Most of the water collected is used to provide water to the garden.

Directed Pumped

This kind of more sophisticated rain water collection system is the most well-known and, in most cases, the easiest to install, particularly for residential properties. Water harvested is easily transported to toilets and other appliances with the help of the pump, which is located in the tank that subsurface. In addition, a small amount of mains water is pumped to the tank to ensure water supply should the tank be in danger of going dry. These systems typically include two pump configurations for industrial installations (duty and standby).

Undirected Pumped

The flow from the outputs of this kind of rain water harvesting structure does not depend on gravitational force. Instead, it pumps the water collected into a tank that could be located on the surface or structure. A booster pump can be used to supply pressure-controlled water. One of the significant benefits of this system is that booster pumps can be customized to accommodate the demands for flow and pressure of a building with incredible flexibility.

Retention Ponds

Using natural procedures such as decomposition, alleviation, inactivating microbes and soil purifying, retention ponds are designed to catch surface runoff water and improve water quality. Although they usually have a mud bottom, this type of retention pond may have the option of a concrete liner. The most frequently used use is for the water that is collected and then retrieved through pond harvesting. However, it is also utilized to replenish groundwater, irrigation, and other unpotable uses.

Underground storage

In areas where most of the rainfall is recorded within a year, underground storage tanks are frequent. Subsurface storage tanks experience very little evaporation and are also insulated. In addition, if they are located below freezing point, water contained in them is not frozen, which is an enormous advantage over surface storage tanks. They should connect to an electrical pump to provide an outlet with water kept in underground storage tanks.

Rainwater harvesting techniques

Surface Runoff

Rainwater is emitted from the surface in urban regions. If you use the right techniques, the runoff can be collected and used to replenish the aquifers.

Rooftop rainwater harvesting

It’s a method for collecting rainwater right at the source. Rooftop harvesting is the process of collecting rainwater from the roof of a house or building through the transformation of it into an evaporation system. It could be channeled to a synthetic recharge facility or stored within tanks. If it is used correctly, this technique can be less costly and highly beneficial, and will contribute to raising the groundwater levels in the local area.

Importance of rainwater harvesting

The capacity to store rainwater to be used later on is the primary advantage of rainwater harvesting. The water stored could be used to rejuvenate groundwater and increase its quality in the same way that it can be consumed directly. In addition, by increasing the level of groundwater, it is easier to get. Tube wells and wells will not dry as they feed to the level of the ground.

This increases the fertility of the soil. Rainwater collection helps to control surface runoff and helps to reduce soil erosion.
A water shortage is a frequent problem in areas lacking irregular rain. Although it’s not completely solved, it can be reduced by collecting rainwater. Rain collecting is the best solution to water-related issues in areas where the rainfall is inconsistent all year long.

Conclusion

Collecting and harvesting rainwater is an appropriate method to tackle the water shortage prevalent in many areas of the globe. Rainwater harvesting is an essential and crucial element in establishing an environmentally sustainable water resource pathway for every community. Since local water resources are stretched to accommodate the growth of populations and economic development, New water supply strategies and approaches will be required to meet this need.
