With water becoming increasingly scarce and expensive, using rainwater at home is a great way to save money and conserve our precious resources. Rainwater is free, abundant, and can be used for a variety of purposes around the home. In this post, we’ll go over the various ways to collect, store, and how to use rainwater at home.

Collection Methods for Using Rain Water at Home

There are several methods for collecting rainwater, each with its own advantages and disadvantages. Having a rainwater harvesting system is a good idea! 

Roof Collection

One of the most common methods of rainwater collection is through a roof system. This typically involves installing gutters along the edge of the roof and directing them to a downspout that leads to a rain barrel or other storage container. Roof collection systems can be relatively inexpensive and easy to install and maintain. However, they are not as effective in areas with low rainfall or where the roof is dirty, as debris can clog the gutters and downspouts.

Surface Collection

The surface collection method involves directing rainwater into a shallow basin or depression in the ground. It can be a simple, low-tech solution for areas with high rainfall and low evaporation rates. However, it is less effective in drier areas and may require more maintenance and cleaning than a roof collection system.

Hydroponic Systems

Hydroponic systems use water as part of the growing medium for plants. These systems can be designed to capture and reuse rainwater, reducing the need for expensive irrigation systems and minimizing water waste. Hydroponic systems can be expensive to set up and maintain, but they have the added benefit of producing fresh, healthy food. How to Start a Garden

Storage Methods

Once you have collected rainwater, you need to store it for later use. There are several storage options to choose from. If rainwater is your primary water supply, then check out these catchment system options. 

Use of Rain Barrels

Rain barrels are a relatively inexpensive and easy way to store rainwater. They can be purchased at most hardware stores or online and are designed to fit under downspouts. However, they are limited in the amount of water they can hold and may need to be emptied and cleaned periodically to prevent bacteria buildup.

Cisterns

Cisterns are larger storage tanks that can hold hundreds or even thousands of gallons of water. They are more expensive than rain barrels and require professional installation, but they can provide a more reliable source of water for larger households or agricultural needs. Cisterns can also be buried underground to reduce the visual impact and to help protect them from freezing temperatures. Cisterns are a great storage tank for water, so if you’re thinking about what to do with collected water, this is a good idea! 

Ponds

Ponds are another option for storing rainwater. They can be created by digging a shallow depression in the ground and lining it with an impermeable material such as plastic or clay. Ponds can provide a natural habitat for wildlife and be used for irrigation, landscaping, and even swimming. However, they require more maintenance than other storage methods and may not be suitable for all climates or soil types. Ponds are one of the easiest long-term ways to collect and store water! It also allows for water conservation in a more natural storage environment. 3 Ways to Prevent Flooding

Using rainwater for irrigation can also reduce water bills and conserve municipal water supplies.

Cleaning

Rainwater can be used for cleaning various household items and surfaces. From washing your car to cleaning your windows, using rainwater instead of tap water can save money and reduce the amount of chemicals needed for cleaning.
