A rainwater collection system harvests rainfall from roofs or other waterproof surfaces. Residential rainwater collection uses water captured and stored at a home or other type of residence. The water is most commonly collected from roof structures and gutters. The system connects these areas, along with rain barrels, to gather rainwater and store it for later use. This water is most commonly used for gardening since it is not purified for drinking water. Since homeowners will use the water on the site of collection, there is no need to transport it to other locations. Because of this, you may want to carefully consider where you choose to locate your rain barrel. A residential rainwater irrigation system is a sustainable system that saves money and conserves public water. This way, you wont be wasting valuable filtered drinking water on your plants, gardens, and sprinkler systems, and this will save you money on your water bill which can add up substantially each year.

There are significant benefits of rainwater collection, and homeowners and residents can use rainwater to nourish trees, gardens, flower beds, and yards. The typical components of a basic system are downspouts from the roof level, a modified gutter system, pipes to carry water, and rain barrels for storage.

The benefits of rainwater irrigation setups are amplified in water scarce areas  (e.g. Los Angeles), but they’re valuable in many climates. These benefits include:

  • Water conservation
  • Saving money on utility costs
  • Positive environmental impact
  • Increase the value of a home or residence
  • Reduce damage to home and foundation from rains and water

A rainwater irrigation system can be a simple arrangement that directs rainwater to a garden plot or flower beds. Or, they can be expansive systems that can irrigate large areas of ground. It’s up to you to evaluate the needs of your lawn to decide how extensive of a system you may need. Basic rainwater systems are easy to create and install, but more complicated systems can get a bit tricky, so make sure you have some Gutter Cleaning Pros nearby in case of any problems. The structure of a rainwater irrigation system can range from a downspout and barrel to sophisticated contractor-installed systems for all types of water usage. Many people prefer to do it themselves, and the DIY rain collection and irrigation systems can be quite effective, creative, and require low-cost investments of time and materials. These systems can also add flair to any basic garden set up and collected water can be used in water falls and other aesthetic garden features.

Rainwater harvesting can be a primary source of water. Like wells, rainwater collection can provide water for outdoor irrigation and indoor uses like clothes washing and cleaning. With more advanced systems, households can convert rainwater into safe drinking water. This, however, is not typical, and these types of systems can be costly to install and maintain. However, if you live in an area where there is limited drinking water, a rainwater system may be a great idea.

Rainwater is heavy, and the system for storage must support the weight of water. Simple barrel set-ups typically have support for the barrel and sit on a bed of gravel to promote water flow and avoid creating muddy areas.

Water collection containers or barrels can work as a single container or have connections and link two or more containers to handle overflow and regulate irrigation. Containers should be covered and well maintained. They require periodic cleaning.

The gutters on the roof are part of the water intake, and a successful system must keep the channels free of debris that can clog the system and interfere with water collection.
