Collecting rainwater, otherwise known as rainwater harvesting is an ancient practice still used throughout the world today. The main reason people collect rainwater at their home is to use for garden irrigation systems or simply to water their plants.
Collecting rainwater can be as simple as setting out a bucket to catch the rainfall. Or you can use a much more complex system. Either way, the basic components that you need for rainwater harvesting are all the same.
The Standard Process for Collecting Rainwater
This is the area that initially catches or captures the rainfall. Typically, it is the roof of the house or building that is the basis of the rainwater harvesting.
The conveyance system in which the water travels from the catchment system to the next part of the collection process, the storage system. On a house or building, the conveyance system is what the rainwater uses as it travels off the roof downward. It would be the gutters, downspouts, and so on.
This is where the rainwater is kept and collected until it is distributed to its final destination. It can be anything from a barrel to an actual water tank. As mentioned, it all really depends on how technical or advanced you want to get. Of course, if you have a top of the line expensive system for harvesting rainwater, you are not going to catch it in an old barrel you picked up at the junkyard or thrift shop. Be sure that it is big enough to hold the amount of rainwater you intend on collecting.
Although, keep this in mind. If you have to move the storage containers, you have to make sure they are still light enough to lift. If you are a beginner, be aware that the containers will be filled with a lot more water more than you originally anticipate.
This is the end result. How are you going to distribute the water to its intended source? If you collect rainwater, which is the economical friendly thing to do, you most likely have plants or a garden. Perhaps a very large garden. You might own a farm. No matter what you are watering, you have to distribute the water.
If you are up to the task or the area isn’t exceptionally large, you can use a watering can. Either siphon it from the storage container or dip it in and go about your business. If you have a larger area to garden, you probably have an irrigation set up and ready to go.
