Installing a Simple Rainwater Collection System
If you're interested in harvesting rainwater for your small garden but don't want to invest in a complex system, a simple rainwater collection system may be a good option for you. Here are the basic steps for installing a simple rainwater collection system:
- Choose a location: The ideal location for a rainwater collection system is under a downspout. This will allow the system to capture as much rainwater as possible. If you don't have a downspout, you can still install a system near a gutter or roof edge where water runoff is high.
- Install a barrel or container: You can purchase a rain barrel or use any large plastic container with a sealed lid. Make sure the container is clean and free of debris before installation. Place the container on blocks or a stand to elevate it off the ground.
- Install a diverter: A diverter is a device that redirects water from the downspout into the rain barrel when it's empty. When the barrel is full, the diverter automatically sends excess water back through the downspout. There are various types of diverters available for purchase online or at home improvement stores. Follow the manufacturer's instructions for proper installation.
- Add a spigot: Cut a hole near the bottom of the container and install a spigot. The spigot will allow you to easily access water from the container. Use a rubber washer to prevent leaks.
- Install an overflow system: In case of heavy rainfall, your rain barrel may fill up quickly and overflow. It's important to install an overflow system to prevent damage or flooding. This can be as simple as attaching a hose from the overflow port on the diverter to a nearby garden bed or drain.
- Maintain your system: Regularly check and clean your rainwater collection system to prevent debris buildup. You should also ensure that the container is covered to prevent mosquito breeding.
By following these simple steps, you can set up a basic rainwater collection system to capture and reuse rainwater for your garden. Not only is it environmentally friendly, but it can also help you save money on water bills.
Filtering and Purifying Your Rainwater
Filtering and Purifying Your Rainwater
Once you've collected your rainwater, it's important to filter and purify it before using it for drinking, cooking, or bathing. Filtering and purifying your rainwater will remove impurities and ensure that it's safe for consumption. Here are some methods for filtering and purifying your rainwater:

These filters typically use a screen or mesh to trap the particles and prevent them from entering your water supply. Sediment filters are relatively inexpensive and easy to install, making them a popular choice for homeowners.
- Activated Carbon Filters: Activated carbon filters are designed to remove chemicals such as chlorine, pesticides, and herbicides from your rainwater. These filters use a layer of activated carbon to absorb the chemicals and prevent them from entering your water supply. Activated carbon filters are more expensive than sediment filters but are necessary if you plan to drink or cook with your rainwater.
- Ultraviolet Purifiers: Ultraviolet purifiers use UV light to kill bacteria and viruses in your rainwater. These purifiers are easy to install and maintain, and can be used in conjunction with sediment and activated carbon filters for added protection. Ultraviolet purifiers are a must-have if you plan to use your rainwater for drinking or cooking.
- Reverse Osmosis Systems: Reverse osmosis systems use a semi-permeable membrane to remove impurities from your rainwater. These systems are highly effective at removing contaminants such as lead, arsenic, and fluoride, but are more expensive than other filtration methods and require professional installation.
It's important to note that filtering and purifying your rainwater is essential for ensuring that it's safe for consumption. In addition to these methods, it's also important to regularly clean and maintain your rainwater collection system to prevent the buildup of bacteria and other impurities.
