How do you make a rainwater harvesting model?

The easiest way to harvest rain is through a rain barrel (make your own from a large trash can or an old drum) linked to a pipe fitted to collect rainwater from the rooftop and verandah of the house.To prevent the barrel from becoming a mosquito breeding ground, fasten a tight-fitting top to it, and screen the ends of

What is meant by rainwater harvesting model?

Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water.

What are the different types of rainwater harvesting?

7 Different Types Of Rainwater Harvesting Systems

  • Water Butt. One of the most basic types of rainwater harvesting systems; water Butt collects rainwater in a container from natural rainfall and/or drain pipes.
  • Direct-Pumped.
  • Indirect Pumped.
  • Indirect Gravity.
  • Gravity Only.
  • Retention Ponds.
  • In-Ground Storage.

Where is rain water normally stored?

What are the modern methods of rainwater harvesting?

Modern Methods of Water Harvesting  The Modern methods of rainwater harvesting are categorized under two, they are Artificial Recharging and Rain Water Harvesting.  The former is classified into Absorption Pit Method, Absorption Well Method, Well cum Bore Method and Recharge trench cum injection well.

Can we use rainwater for drinking?

It is possible, therefore, for us to drink untreated rainwater. This is because rainwater is pure, distilled water evaporated from the sun – nothing else. However, when rainwater falls from the sky, substances from the air and land melt into the rainwater. This water (groundwater) is relatively safe for drinking.

What is ground water harvesting?

Ground water recharge in urban areas. In rural areas, rain water harvesting is taken up considering watershed as a unit. In urban areas, rain water available from roof tops of buildings, paved and unpaved areas goes waste. This water can be recharged to aquifer and can be utilized gainfully at the time of need.
