Different Methods for Rainwater harvesting

There is numerous way to harvest rainwater. Here, I’ve highlighted the best possible ways for Rainwater Harvesting. All these need a lot of caution and knowledge. So please be sure to have a good idea before you start to collect the Rainwater.

Rainwater Harvesting System

So, Let’s dive into the different methods to save rainwater :

1.Catchments

  • It is a kind of storage unit for the water harvesting system. 
  • It is used to store water and release it to the distribution system as per the need.
  • The Water falling on the catchment area is stored for later use.

2.Conveyance System

  • It is a part of a drainage system that is used to transport the water from one area to another.
  • The transportation of rainwater is done without any detention of water
  • The entire network of pipes, guttering, and downspouts are used to deliver the captured rainwater to the containers for storage.

3.First flush

  • It is a device used to carry the dirt from your roofs and divert it from the storage tank.
  • It helps to clean water that will enter your reservoir tank after every raindrop passes through the first flush.
  • By using the first flush, we can use the clean rainwater useful for a long time

4.Filter

  • It is use for removing unwanted materail from rainwater to keep fresh.
  • Filters collect moss, leaves, bird feces, etc. all the while rainwater is coming in contact with them.
  • Hence, When rainwater falls on a roof, it is filter to consume it.

5.Tanks and recharge system 

  • Tanks and recharge structures are the most common ones to harvest rainwater.
  • Perfectly choose the setup you want to use to store the water.
  • The water can be stored in tanks or recharge structures depending on your preference and budget.

 Water harvesting is not just about conserving surface water. It has innumerable applications in areas where rainfalls. However, the land area is not sufficient to store them all for easy access. In such a case, you will need a good recharge system to store the water over the year.

Also, if you don’t have such a big rainwater harvesting system, then no need to worry. You can simply fill a bucket of water and used it to water your plants. And watch them thrive greener and healthier beautifully.

Plants love rain too

Let’s understand the main reasons behind the love for rains of plants :

1.Rainwater is 100% soft water.

 Rainwaters are free of salts, minerals, treated chemicals, and pharmaceuticals. In municipal water, groundwater, and surface water you will find such inorganic matters.

Another reason to harvest rainwater is for the health of your plants. Collecting rainwater and using it can help reduce the salts & chemicals that build up in your soil over time.

The accumulated salts and chemicals can be very bad for any plant, and they can also make them more vulnerable to diseases. This builds up in the soils of your potted plants because dirt doesn’t absorb water like a sponge.

2.Rainwater is slightly acidic—naturally!

Rainwater is acidic in nature

The ideal range of a plant’s soil PH level is between 5.5 to 6.5 which is acidic in nature. And Surprisingly, it is the exact Ph range for rainwater!

Likewise, city water PH levels range above 8.5 which is alkaline in nature.

Also, Greywater i.e water from a washing machine or bathroom sink has the same PH level as high as 10.5. Which depends on the types of soaps and detergents that are in it. 

Here, where the role of rainwater comes into the picture. Rainwater helps to flush out the soil which helps to keep your soil pH in perfect balance organically. Hence, irrigation of rainwater is essential. 

3.Rain contains nitrates—an important macro-nutrient

The rainwater contains ‘Nitrate’. Nitrate does what most nitrogen-based fertilizers can’t. It enters directly into the root system and promotes the growth of the plant. 

While the majority of the nitrogen that makes its way through soil is in the form of ammonium. Nitrate is the most bioavailable and easily absorbed by plants because it dissolves in water.

During the rainy season, you should use less fertilizer. As Rainwater itself acts as a great fertilizer for plants

Phosphorus and potassium are also essential for healthy plant growth. Rainwater, however, contains none of these. Rain is very infrequent in some areas, Hence it is important to supplement with fertilizers in the off-season.”

Rainwater is the ultimate sustainable resource. Rainwater harvesting isn’t a new idea – civilizations have been using rain as a source for irrigation since the beginning of agriculture. As far as the earth’s water goes, rainwater is the purest form.

In Rainy Season, Let nature do the work to water your plants.

In nature, plants have lots of little rains that fall on them. These small raindrops seep through the leaves and nourish the roots, making them lush and healthy. The rainwater harvesting technique is great. Because due to it, many plants have plentiful microscopic roots that are saturated with water.

When these roots are exposed to water, they start to grow rapidly. As a result, most of our lawns, gardens, and other aquatic areas would benefit from having a lot more rainwater harvesting plants.
