It got so bad that I finally decided that enough was enough and just collected all of the water myself. The process wasn’t too complicated, and you’ll see how easy it is below! Unfortunately, it’s not every day we get a chance to collect Rainwater at home without having our roofs leak.  

Rain is considered a natural resource that has always been wasted before.  This is frustrating for most of us because it doesn’t come often, and its benefits are essential. So, this article is for you. You will learn how to collect Rainwater in an apartment with just one simple trick!

How to Collect Rainwater in an Apartment

6 Steps to Follow on How to Collect Rainwater in an Apartment

Step One: Determine

First, you will need to determine which of the many types of rainwater collection containers are best for your apartment. For instance, you can use barrels, cisterns, trays, or a combination of each, depending on how much water capacity you want or what will work best in your space.

Just remember that when using barrels, you will need to place them on a sturdy surface that can hold their weight, such as a deck or patio. And if you are using cisterns, make sure that the tank is elevated, so the water does not stagnate and becomes a breeding ground for mosquitoes.

If you want to collect a lot of water, you may need multiple tanks and barrels. You can also buy commercially made rainwater collection systems to install on your roof. These are available in many styles and sizes for apartments and homes with more significant properties.

Step Two: Mark the Area

Once you have determined what type of container you will be using, mark the area where you want to place it. Try to choose a spot as level as possible and in a sunny location if possible. This will help speed up the process of evaporating and purifying the water.

Type of Container Using

If you are using barrels, place a piece of wood or some other type of platform on which to stack them. The higher the barrels, the more water you will collect. But make sure that whatever you use can support the weight of the barrels and water, and choose a location where the barrels can be stacked without falling off.

It is also a good idea to place your rainwater collection site in the shade. This will help keep the water cool when it is in storage, which will prevent the growth of algae and bacteria. A good location for this is under the overhang of your roof.

Step Three: Install the Gutters

Once you have marked the spot for your rainwater collection system, install gutters in that area if possible. It is even better if they can be routed to your barrels or storage tanks without any sharp angles or dips. This will help keep the water flowing without any blockages.

 Install the Gutters

If you are using cisterns or other large storage tanks, make sure that you have a way to pump the water from the gutters into the tank. You can buy electric pumps for this purpose or use a manual pump handy with tools. If you cannot install gutters, you can improvise by using a PVC pipe to funnel the water from the roof to the collection container.

Just make sure that the pipe is big enough to handle the flow of water and elevated above the ground so that it does not get clogged with dirt and debris. It is also good to place a screen over the pipe to keep out bugs and other small creatures. This will help in how to collect Rainwater in an apartment.

Step Four: Connect the System

Once you have installed your gutters or funnel, connect them to your rainwater collection container. Using barrels is simple enough – use a hose to direct the water from the gutters into the barrel. If using cisterns or other large tanks, you will need to install a pump to get the water from the gutters into the tank.

Make sure that the pump is big enough to handle the amount of water you are collecting. You may also want to use a filter to keep out any leaves, twigs, or other objects that could damage the pump. You can use both types of filters for extra protection to be on the safe side.

If you use multiple barrels, you will need to create a system for distributing the water evenly between them. You can do this by installing a pipe between the barrels or by using a hose to lead the water from one barrel to another. However you decide to do it, make sure that there is an overflow system in place so that if for some reason all of your barrels fill up at once, excess water can be drained off safely.

Step Five: Disinfect the System

Before using it, do a thorough cleaning of all parts of your rainwater collection system. This is especially important if the system has not been used in a while or previously used to collect dirty water. Then, use a bleach solution of one part bleach to nine parts water to disinfect all of the components of your system.

Be sure to rinse everything thoroughly afterward to remove all traces of bleach, which is both dangerous to humans and damaging to plants. After everything has been sufficiently cleaned and rinsed, fill the system with water to test it. This is also an excellent time to install any filters or other purification systems that you might want to use.

If there are leaks in your system, this will reveal them before the system is used. Once you have ensured that everything is in good working order, you can start collecting Rainwater for your garden! This information will help you learn how to collect Rainwater in an apartment.

Step Six: Maintain the System

Once your rainwater collection system is installed, it is important to keep it in good working order. This means regular cleaning and maintenance, especially if using cisterns or other large storage tanks. In addition, make sure that all of the components are in good condition and replace any damaged or worn-out parts.

Disinfect the System

Also, make sure that the system is draining properly. You may need to dig it out from underneath any mulch or other material you have used as a ground cover. Finally, if there are animals in your area, be sure to keep the gutters and storage tanks covered to keep them away – otherwise, they might take up residence and start making a mess of things!

If you have any questions about setting up or maintaining a rainwater collection system, be sure to ask an expert. Many people can help you get started – your county extension agent, local rainwater harvesting group, or even a plumber or contractor specializing in these systems.

How Do You Get Rainwater on Your Balcony?

Rainwater can be collected from balconies in apartment buildings. A typical balcony is usually covered with a metal grate to protect the building walls and allow airflow under the roof. The grate creates a gutter for the Rainwater and leaves no space for water to accumulate except for small spaces between some of the bars.

Rainwater can also be collected from rooftops. Rooftop gardens are popular in many parts of the world, especially where there is little soil available for gardening. By building a shallow swale along the edge of the rooftop garden and directing Rainwater into it, you can use all but one or two inches of rainfall to water your plants.

Collected From Balconies

You can also use rain barrels to collect rooftop rainwater. For example, a downspout from the roof can be directed into a rain barrel, which can then be used for water plants or other purposes. Thanks for reading about how to Collect Rainwater in an apartment.
