There is a lot you can discover that you want on the internet and if you type into the search bar rainwater, you will see a variety of posts on whether it’s safe to drink. When you consider that half of the world dwells in a climate where water scarcity implies that rain is taken in when it falls, and is then with no hesitation in a way that is a bit surprising to hear some of the comments on drinking the water. 

Of course, the doubters reside in cities that are affluent and most likely do not consume tap water, but purchase expensive bottles of water instead. A few people gather rainwater that falls onto the rooftops of their homes. The water then is able to flow through their cast iron drainage to the barrel or vat. 

The issue of whether or not this is drinkable is probably one of necessity. In many countries, it is nearly irresponsible to not keep a water barrel in the garden that is collecting from the downpipes of cast iron gutters when there is a plant to be watered.

There are times when there is an absence of rain in the summer that the hosepipe ban is issued, and it can be in effect for months. In this case, the gardener who is prepared will have a large bathtub of water to water his garden. All the water that was previously collected by the flow of water along the guttering made of cast iron the house will serve to protect his flower beds.
