Water bills are rising, and many of us are looking for ways to save money while also being more environmentally conscious. Traditional water sources are becoming less reliable due to climate change and overuse, making it essential to find sustainable alternatives.
It can be frustrating to see your water bill climb higher each month, especially when you know that a significant portion of that water could be sourced for free from the rain. Additionally, the environmental impact of using treated water for gardening and other non-potable uses is significant. You might feel overwhelmed by the idea of setting up a rainwater collection system, thinking it’s too complicated or expensive.
The good news is that setting up a DIY rainwater collection system is easier and more affordable than you might think. With a few simple materials and some basic know-how, you can start collecting rainwater to use in your garden, for washing your car, or even for flushing toilets. This guide will walk you through the process step-by-step, making it accessible and straightforward.
Choose Your Collection Method
When it comes to DIY rainwater collection, the first step is to decide on the method that best suits your needs and space. There are several options available, each with its own set of advantages and considerations.
Rain Barrels
Rain barrels are one of the most popular and straightforward methods for collecting rainwater. They are relatively inexpensive, easy to install, and can be placed under any downspout to collect runoff from your roof.
Advantages:
- Cost-Effective: Rain barrels are affordable and can often be found at local hardware stores or online.
- Easy Installation: Setting up a rain barrel requires minimal tools and effort.
- Versatile: They can be used in various locations around your home.
Considerations:
- Limited Capacity: Most rain barrels hold between 50 to 100 gallons, which may not be sufficient for larger gardens.
- Overflow Management: During heavy rains, barrels can fill up quickly, so an overflow system is necessary.
Steps to Set Up a Rain Barrel:
- Choose a Location: Place the barrel under a downspout where it can collect the most water.
- Prepare the Downspout: Cut the downspout to fit into the top of the barrel.
- Install a Screen: Place a screen over the top to keep out debris and insects.
- Add a Spigot: Install a spigot near the bottom for easy access to the water.
- Set Up an Overflow Valve: Ensure excess water can be diverted away from your home.
Rooftop Harvesting
For those with larger water needs or more space, rooftop harvesting systems can be an excellent option. These systems collect rainwater from your roof and direct it into a larger storage tank.
Advantages:
- Higher Capacity: Rooftop systems can store significantly more water than rain barrels.
- Efficient Collection: They can capture a large volume of water quickly.
Considerations:
- Higher Initial Cost: These systems can be more expensive to set up.
- Complex Installation: Requires more planning and effort to install.
Steps to Set Up a Rooftop Harvesting System:
- Install Gutters and Downspouts: Ensure your roof has gutters to direct water into downspouts.
- Choose a Storage Tank: Select a tank that fits your space and water needs.
- Connect the Downspouts: Direct the downspouts into the storage tank.
- Install Filters: Use filters to remove debris before the water enters the tank.
- Set Up a Pump: If needed, install a pump to distribute the water.
Underground Tanks
For those looking for a more permanent and high-capacity solution, underground tanks are an excellent choice. These tanks are buried in your yard and can store thousands of gallons of water.
Advantages:
- Large Capacity: Ideal for extensive water needs.
- Space-Saving: Hidden underground, they don’t take up yard space.
Considerations:
- High Cost: More expensive to install due to excavation and tank costs.
- Complex Installation: Requires professional installation and planning.
Steps to Set Up an Underground Tank:
- Plan the Location: Choose a spot in your yard that is accessible and suitable for excavation.
- Excavate the Area: Dig a hole large enough to accommodate the tank.
- Install the Tank: Place the tank in the hole and secure it.
- Connect the Downspouts: Direct water from your roof into the tank.
- Set Up a Pump and Filtration System: Ensure you have a way to access and use the water.
Gather Necessary Materials
Once you’ve chosen your collection method, the next step is to gather all the necessary materials. Having everything on hand before you start will make the process smoother and more efficient.
Rain Barrel or Tank
The most critical component of your system is the container that will hold the collected rainwater. Whether you choose a rain barrel, a rooftop tank, or an underground tank, make sure it is durable and suitable for your needs.
Considerations:
- Size: Choose a size that matches your water needs and available space.
- Material: Look for food-grade plastic or other safe materials to avoid contamination.
- Lid: Ensure the container has a secure lid to keep out debris and insects.
Gutters and Downspouts
To direct rainwater from your roof into your collection system, you’ll need gutters and downspouts. These components are essential for efficient water collection.
Considerations:
- Material: Choose durable materials like aluminum or vinyl.
- Size: Ensure the gutters and downspouts are large enough to handle heavy rainfall.
- Installation: Properly install and secure them to your roof.
Screen or Filter
A screen or filter is necessary to keep leaves, twigs, and other debris out of your collected water. This helps maintain water quality and prevents clogs.
Considerations:
- Mesh Size: Choose a fine mesh to catch small particles.
- Placement: Install the screen at the top of your barrel or tank.
Spigot
A spigot allows you to easily access the collected water. It should be installed near the bottom of your barrel or tank.
Considerations:
- Material: Choose a durable, rust-resistant material.
- Installation: Ensure it is securely attached and doesn’t leak.
Overflow Valve
An overflow valve is crucial for managing excess water during heavy rains. It prevents your barrel or tank from overflowing and causing damage.
Considerations:
- Placement: Install near the top of your barrel or tank.
- Direction: Ensure the overflow is directed away from your home and foundation.
Build Your Rainwater Collection System
With your materials gathered, it’s time to build your rainwater collection system. This section will guide you through the process step-by-step, ensuring you set up a functional and efficient system.
Position the Barrel

Next, you’ll need to modify your downspout to direct water into your barrel or tank. This step is crucial for efficient water collection.
Steps:
- Measure and Cut: Measure the downspout to fit into the top of the barrel and cut it accordingly.
- Attach a Diverter: If needed, install a diverter to direct water into the barrel while allowing overflow to continue down the downspout.
- Secure the Connection: Ensure the downspout is securely attached to the barrel.
Install the Spigot
Installing a spigot allows you to easily access the collected water. This step requires some basic tools and careful placement.
Steps:
- Drill a Hole: Drill a hole near the bottom of the barrel for the spigot.
- Insert the Spigot: Place the spigot into the hole and secure it with washers and nuts.
- Seal the Connection: Use waterproof sealant to prevent leaks.
Add an Overflow Valve
An overflow valve is essential for managing excess water during heavy rains. This step ensures your system can handle large volumes of water without overflowing.
Steps:
- Drill a Hole: Drill a hole near the top of the barrel for the overflow valve.
- Insert the Valve: Place the valve into the hole and secure it.
- Direct the Overflow: Attach a hose to the valve and direct the overflow away from your home.
