Rainwater Harvesting: How To Do At Home? How To Use?

So the rains have probably already reached you, or are about to make an appearance soon. Either way, it’s a great time to try rain water harvesting at home, because if you’re interested in a greener lifestyle (we’re assuming that’s why you’re reading us, right?), reusing the water that comes in the form of rain can be a great option to start with. And it’s actually easier than it sounds.

Game? If you nodded yes, or if you’re still thinking about it, we’re going to tell you the easiest and most basic steps that you can try at home, and also a few ways in which you can use the water.

What Is Rain Water Harvesting?

Rain water harvesting means using the rain water for your different water-based activities, instead of just letting it flow away and get wasted. Makes some sense right? Especially if you think of how much water we get in the form of rains in those precious monsoon months and how much of it goes to waste.

From Where Do You Collect Rain Water And How?

You can start collecting it from your roof, at your balcony or terrace, your porch, your garden, any water body near where you are based, such as a nearby lake or river. You can place a pipe on your roof’s water outlet and collect it in a drum, or place containers on your terrace, balcony, garden, porch and such.

Where Can You Use It?

You can use it almost anywhere, except drinking (though there are some more advanced methods by which rain water can also be converted into drinking water, we’ll share about that separately). The immediate areas where you can use the rain water is for watering your plants, cleaning the car and the house, using it for your livestock or pets and such. The best part about rain water harvesting is that you can also store it up for later use, especially when water supply is not enough or not readily available.

Won’t The Water From The Roof Be Dirty?

Yes, it is possible that the rain water you collect from the roof using a pipe will get dirty. If you’re collecting it in buckets or drums, the water may not get contaminated. But if you’re collecting it through a pipe, the dirt on the surface of the roof can mix with the water, making it dirty. To make sure you do not end up collecting dirt-filled water, you can use something known as a first flush device. It will help to remove any dirt, bird droppings or other such contaminants that can mix in the water. The first flush device is a type of valve that will catch the initial water and direct it out of the collection area. As a result, any dirt that may have been present in the first part of the water you’re collecting will not get mixed in the water.

Where To Buy In India

You can check with your local hardware store to see if they do have the device, or get in touch with the following suppliers if they are in your area:

To keep it easy, especially if you’re doing this for the first time, we’d suggest you go for simple rain water harvesting methods by placing containers around your balconies or rooftops, or using a pipe that can direct the water in a container.
