Question

mention any two objectives of rainwater harvesting.

Answer 1

Hint: Rainwater harvesting (RWH) is the processing and storage of rain rather than allowing it to wash away. Rainwater is collected from a roof-like surface and diverted to a tank, cistern, deep pit (well, pipe, or borehole), aquifer, or percolate reservoir.

Complete step by step answer: Rainwater harvesting is one of the easiest and oldest methods of self-supplying water for households and residential and household ventures, typically funded by the customer. However, larger programs for schools, hospitals, and other services can run up costs only if they can be funded by businesses, associations, and government units.
Rainwater harvesting differs from stormwater harvesting as runoff is collected from roofs, not from creeks, drains, roads, or any other land surface. Its applications include irrigation gardens, cattle, irrigation, well-treated domestic use, and domestic heating. Harvested water can also be used for longer-term storage or refilling of groundwater.
Rainwater Harvesting objectives:
1. To meet the increasing demand for water.
2. To raise the water table to the ground.
3. In order to minimize soil erosion.
4. It helps avoid urban flooding due to excess rainfall.
5. The water bill can be decreased in urban areas.
Rainwater harvesting provides an independent source of water during regional water restrictions and is frequently used in developing countries to complement the main supply. It provides water when drought occurs, can help to alleviate floods in low-lying areas, and reduce the need for wells that can maintain groundwater levels. It also contributes to the supply of drinking water, as rainwater is substantially free of salinity and other salts. Applying rainwater harvesting to urban water systems offers a major advantage to both water supply and wastewater systems by reducing the need for clean water in water delivery systems, reducing stormwater production in sewage systems, and reducing stormwater runoff from polluting freshwater systems.

Note: The method of rainwater collection is one of the best strategies and practices to promote the conservation of water. Today, the lack of good water quality has become a big cause of concern. However, Rainwater, which is pure and of good quality, can be used for irrigation, washing, cleaning, bathing, cooking, and other livestock requirements.
