How to Filter Rainwater for Drinking

Azmin Taraporewala
We are struck by a scenario where every drop of water is considered precious. In such times, when water scarcity is at its peak, we must learn the art of filtering rainwater to make it potable.
'Water, water everywhere not a drop to drink! ... It's certain that you have heard of this adage before. We have reached an environmental stage where preservation is considered the most precious theme and recycle the most reverberant. Rains have always been a season full of fun and frolic washing away the dirt on lorries, cars and carts alike.
Rainwater has been indiscriminate and has been pouring in generously to make nature greener and all the more livelier. However, with the present scenario, the environment has served to be a king-sized bed where pollution, population and filth rest their heads comfortably.
They have been successful at ruining the natural ecological balance of the environment and are hell-bent on continuing with their endeavor. Water bodies have been depleting, population increasing and pollution has been pulsating.
As we have been interfering with Nature's course of functioning, we now, have finally arrived at a stage where rainwater has to be filtered for drinking. Some may do this as a part of a DIY activity, some may invest time and energy to simply while away time, and some may go to an extent of doing something concrete for preservation!

Is it Necessary to Filter Rainwater?

Certainly, rainwater has to be filtered before being consumed. There are many who may have this question and may doubt why rainwater has to be filtered and purified before declaring it as potable.
Rainwater in its actual state does not require any purification process, however after polluting factors running strong in creating a disruption in the environment, one has to make an extra effort in making the rainwater drinkable and worth consuming. You may also have a homemade rain barrel to collect rainwater and use it for domestic purposes.

Making Rainwater Potable

Rainwater can be made fit for drinking, provided you follow instructions given in this section of the article. Here is how you would make the water fit for the purpose of drinking.

Preparing the Containers

You may need to have two containers with you. Even if you don't, you may purchase two buckets. Take one bucket and slit off its bottom. Mount this bucket on the other intact bucket. Now, you have got one big bucket to contain the rainwater.

Attaching a Hose Pipe

When you have your big container ready, you may cut out a hole into the bottom of the bucket placed below the bottomless bucket.
Take the hose pipe and measuring the diameter, cut out a hole in the intact bucket's bottom. When the hole is cut out, insert a vinyl hose pipe into the hole. Use a sealant or glue to fix the pipe, thoroughly so that it does not slip out and resist pressure.

Arrange for a Table

Place a table at the site. Cut out a hole in the center of the table. This hole is meant to facilitate the insertion of the vinyl tube through it. Now, place your big container on the table. Make sure that the insertion of the hose pipe is knot-free; any bends may lead to water leakage.

Install Water bottle

A water bottle or large tumbler; anything would do. The only condition is that it should have a considerable storage capacity. Place the bottle underneath the table in such a manner that the hose pipe can easily slide into it.

Purifying Rainwater

When the rainwater filtration model is ready, you must install a polyester padding in between the containers and on top of it, you may place carbon. The carbon will eradicate the chemicals and contaminants present in water.
Change the polyester padding every month so that the sediments that have collected do not block the padding further leading to the particles being released once again in the collected water, making the water unfit for drinking. This is how you harvest water for drinking.
With the instructions mentioned herein, filtering rainwater, no more remains a 'task' to be accomplished. On the contrary, it would be an exciting and productive activity. In this way, we may end up saving water and recycling it for good.
