These are just some of the wonderful benefits of collecting rainwater on your property, especially for emergency purposes. When a natural disaster hits, there will be very limited water resources available. You can protect your family in the case of an emergency with these essentials

Now let’s get into how you can get started with collecting rainwater yourself. 

Is Rainwater Safe? 

Rainwater is generally safe, yes. However, there are some chances that it can become contaminated from chemicals in your roof, bird poop, dead bugs, or anything that can come in contact with the water as it runs off towards the storage container. 

There are many instructions available online for you to create a first flush diverter, which is a mechanical device that will help to remove a big portion of the gunk and debris buildup in your rainwater. 

If you are going to consume your rainwater collection, make sure that you cleanse and purify the water first. It is recommended that you do not DIY your filtration system because of the size of the microbe you are aiming to remove. There are many filtration systems available at an affordable price that can effectively remove the waterborne protozoa and bacteria.

We also suggest that you do a major cleaning once in a while to remove the organic buildup on your roof. By following the above steps, you can be assured that you used the best possible steps to have the safest, cleanest water. 

Equipment You Will Need For Collecting Rainwater

Rainwater collection is more than just placing a barrel outside, hoping that you collected enough water to do your laundry. It involves many different parts and conscious decisions on which materials you use to put it together. 

Catchment Area

Your roof is the most obvious catchment area, it has the largest surface area on your property and does not need to utilize the water itself. Setting up a system that will collect the rainwater runoff from your roof will have the best result.

This could also be the roof of your shed, carport, chicken coop, pickup truck, barn, or anything else that has a large surface area. 

The most important thing to consider is the type of material that is in contact with the rainwater. Some roofing materials such as shingles have a lot of chemicals that will come in contact and contaminate the water. Choose roofing materials that are made out of metal for a more ecologically friendly and safer rainwater collection.

Rain Barrels

Rain barrels are a simple way to collect rainwater. Find a 50 to 100-gallon barrel and place it under your gutter runoff to collect the rainwater from your roof. Rain barrels do not take up much space and are a great start for those who want to see how much water they can collect. 

Wet Collection System

A wet rainwater collection system is quite advanced to set up, however, it has the most return in investment. Using PVC piping, you can create an underwater collection system which collects the downspouts from multiple gutters. Once the underground piping fills up, it will create a pressure which fills up a tank located on your property. 

For this to work, the elevation of the tank must be below the lowest point of the gutters on your property. The higher the gutter, the higher your tank can be. 

Dry Collection System

The dry system involves a large tank that is located underneath the gutters of your house. The pipe that collects the water will dry after each collection because it dumps directly into the large barrel. This system is similar to the rain barrel system, but it allows for more water storage.

There you have it! You can now get started on creating your rainwater collection system and reap the rewards for both you and your family. There are many different systems for collecting rainwater, and it all comes down to how much time and money you want to invest in the creation of it.
