What is Rainwater Harvesting?

Rainwater harvesting is the process of collecting and storing rainwater for later use. It has been practised for centuries, but is becoming increasingly popular as a way to conserve water and reduce reliance on municipal water supplies. There are many different ways to harvest rainwater, but the most common method is to collect it in a cistern or other storage container. Once collected, the rainwater can be used for irrigation, indoor plumbing, or even drinking water. 

In addition to its practical applications, rainwater harvesting also has a number of environmental benefits. By using rainwater instead of treated water from a municipal source, we can reduce our demand on energy-intensive water treatment facilities. In addition, rainwater harvesting helps to recharge groundwater aquifers, providing a natural source of water during times of drought.

How to Design a Place for Rainwater Harvesting?

Designing a place for rainwater harvesting can be a fun and rewarding experience. There are many different ways to go about it, so there’s sure to be something that works well for your home. Here are some ideas to get you started:

  • Consider Installing A Rain Barrel: This is the easiest and most popular way to collect rainfall runoff. A rain barrel collects rainwater through gravity and can store up to 3,000 gallons of water. You can find them at most hardware stores and home improvement stores.
  • Install A Rain Garden: A rain garden is a landscaping feature that helps capture and store rainwater runoff. They consist of small depressions filled with soil, rocks, orúcregs that help slow down the water flow and keep it from running off the surface. Rain gardens can be larger or smaller, depending on how much water they need to trap and store.
  • Dig A Trench: A trench can be used to collect runoff from an area that doesn’t have enough space for a rain barrel or garden, like the side of your house or garage. Just make sure the trench is large enough to accommodate the size of your runoff area and the depth of the groundwater below

Ideas for Rainwater Harvesting 

If you’re thinking about rainwater harvesting for your home, there are a lot of great ideas out there. You can collect rainwater for use in your garden, for washing your car, or even for drinking. Here are some examples of how you can use rainwater harvesting in your home:

  1. Install A Rain Barrel
  2. Create A Rain Garden
  3. Make Your Own DIY Rain Chain
  4. Naturally Recharge Your Wells And Borewells
  5. Set Up A Splash Block
  6. Build A Rain Saucer
  7. A Reservoir For Rain

1) Install A Rain Barrel

Installing a rain barrel is something to think about if you want to reduce your household’s water use and save money. By making this easy investment, you will not only be able to cut down on your own water use, but you will also be able to help cut down on the quantity of water that flows into the storm drain system. A rain barrel connected to a pipe that is customised to collect rainwater from a house’s rooftop and verandah is the simplest and most efficient technique to collect rainwater for later use. You may create your own rain barrel out of a huge garbage can or an old drum.

2) Create A Rain Garden

Putting up a rain garden is one of the many things you can do to help reduce your water use and save money in the process. A rain garden is a small patch of land in your backyard that is specifically designed to collect and store rainwater runoff from your roof, driveway, or other parts of your property. It is a method of landscaping that has a minimal environmental effect and makes use of rainwater to irrigate plants. Your plants will get the nutrients they need, and you’ll be able to limit the amount of runoff that occurs as a result of the water’s journey through the soil and into the groundwater. In addition to this, it will provide you with some more water that may be utilised for cleaning or flushing the toilet.

3) Make Your Own DIY Rain Chain

A DIY rain chain is a simple way to collect rainwater and turn it into usable water. This system collects rainwater from the roof and distributes it to a container located below. Buckets, containers, and even barrels may be used to create a rain chain. You just need some rope, a pulley, and connections. First, secure one end of the rope to the top of a container or bucket. The other end of the rope should then be tied to the pulley. Now, connect the home’s water supply and observe as the bucket or container fills with water from the roof. Untie the knot from the pulley when it is full, and let gravity do the rest. This chain comprises linked plastic buckets, hoses, and faucets. When it rains, water runs from the spout of one bucket to the faucet of the next bucket, and so on, until it reaches the sink or final bucket.

4) Naturally Recharge Your Wells And Borewells

Installing a recharge pit close to the bottom of your existing well is one approach of gathering rainwater for usage inside of your house. It will be possible for you to refill your borewells without needing to transport water from a faraway source if you do this. Recharging pits for borewells are a smart investment due to the fact that they force surface water deeper into the aquifer where it originates. A recharge pit typically has a diameter of one metre and a depth of six metres. Its interior is often lined with concrete rings that have holes. These holes enable water that has been filtered and de-silted to seep from the sidewalls, which raises the level of the groundwater table.

5) Set Up A Splash Block

This is a small area of your roof that will collect rainwater runoff from the roof. Next, you’ll need to install a rain barrel or catchment system. Installing a splash block is a great way to direct rainwater away from the structure’s foundation. During a rainstorm, it is a piece of concrete or plastic that is generally rectangular in form, and it is positioned under the downspout that conveys rainwater from the roof of a home. It mitigates the eroding effects of the pouring water by absorbing the force of the water that is being redirected from the roof, and it also prevents holes from being created in the garden as a result of the force of the water.

6) Build A Rain Saucer

Build A Rain Saucer

With rain saucers, you can collect rainwater swiftly and easily. They fill up surprisingly quickly and can be used to collect rainwater quickly and easily.  Rain saucers are compact, simple to use, and can be positioned almost anywhere inside of your home. They collect the rainwater that runs off the roof and direct it into a catchment area that is located below the building. The rain saucer, which unfolds into the shape of a funnel to collect rainfall and fill the containers, resembles an inverted umbrella from the outside. As a result of the fact that this simple device collects rainwater directly from the atmosphere, the risk of contamination is significantly reduced.

7) A Reservoir For Rain

A reservoir is a natural or artificial body of water that stores precipitation runoff. This runoff can come from roofs, downspouts, gutters, and any other point where water accumulates. When it rains, the water runs off these surfaces and into the reservoir. To build a reservoir, you’ll need a large container that can hold enough water to provide your household with drinking and irrigation needs for several months. The best container option is a concrete or plastic storage tank, which will withstand high water pressure and temperatures. You’ll also need a drain pipe to drain the reservoir and an outlet pipe to allow water to flow into the house. You should also plan on setting up a pump system to ensure that water flows constantly into the reservoir.


So, what can you do to help make the planet sustainable? Plenty! We’ve outlined seven ways for you to get started below. And don’t forget – recycling waste water is a huge part of sustainability, so please consider investing in a rainwater harvesting system for your home or business. With just a little effort, we can all make a big difference in preserving our planet for future generations. Let us know how you plan to go green.
