Harvesting rainwater is an effective way to reduce your environmental impact, save money and conserve this valuable resource. With a few simple steps you can start collecting and using this vital resource today!

Collection System

The first and most important requirement for rainwater harvesting is setting up a collection system. This consists of an appropriate roofing system, gutters, downspouts, pipes, and storage tanks. The roofing should be designed to provide an adequate catchment area and should be made of a material that is resistant to corrosion and wear caused by the elements. Gutters and downspouts should be installed properly to ensure the water reaches the storage tank. Pipes should be chosen carefully as they need to be able to withstand changes in temperature, pressure, and chemical composition of the water. Finally, the storage tank must be chosen based on its size, durability, and ability to protect against bacterial contamination.

Filtration System

Once the collection system has been installed, it is important to set up a filtration system for rainwater harvesting. This system includes pre-filters such as screens or mesh filters that can remove debris from the incoming water before it enters the tank. There are also various sediment filters which can remove different sized particles from the water depending on their size rating. Finally, carbon filters can be used to improve the taste of the harvested water by removing organic compounds and other contaminants.


In order for harvested rainwater to be used in residential or commercial applications, pumps are required in order to move it from its storage tank into its desired destination. The pumps must have adequate power and should also have features such as variable speed control so that they can adapt to different demands depending on how much water is being used at any given time.

Disinfection System

Finally, it is essential that a disinfection system be installed in order to ensure that all harvested rainwater is safe for use in residential or commercial applications. This can include UV light treatment systems or chlorination systems which will kill any harmful bacteria or viruses present in the water before it is used for drinking or other purposes.

Types of Rainwater Harvesting Systems

Rainwater harvesting is the process of collecting and storing rainfall for future use. There are multiple types of rainwater harvesting systems that can be used to capture, store and use the collected water. The most commonly used systems include rooftop harvesting, surface runoff harvesting, and subsurface flow systems.

Rooftop Harvesting is a system that collects water from rooftops and other impervious surfaces such as driveways, patios, car parks etc. The water is then stored in a tank or cistern for future use. This type of system is best suited for areas with high rainfall intensity and relatively low evaporation rates since it captures the most amount of rainwater available.

Surface Runoff Harvesting is a system that collects water from paved or unpaved surfaces such as streets, sidewalks, open fields etc. It uses natural contours in the land to direct the flow of runoff into catchment areas where it can be stored for future use. This type of system is best suited for areas with relatively low rainfall intensity since it captures less water than rooftop harvesting but still provides a significant amount for storage.

Subsurface Flow Systems are systems that capture and store rainfall beneath the surface of the ground. This type of system utilizes underground structures such as trenches or infiltration galleries to collect and store water in aquifers or other underground reservoirs. Subsurface flow systems are best suited for areas with low evaporation rates and moderate rainfall intensities since they provide more efficient water storage than rooftop or surface runoff harvesting methods.


One of the main factors to consider when designing a rainwater harvesting system is the location. The collection area should be close to the point of use, preferably downhill from it, to take advantage of gravity flow. It should also be situated in an area with adequate drainage so that excess runoff can be safely discharged. Additionally, it is important to ensure that the collection area does not overflow during peak rainfall events.

Storage Capacity

The size of the storage tank should be carefully considered in order to ensure that it can adequately store enough water for a given application. It is important to calculate the expected amount of rainfall and determine what capacity storage tank would be required in order to meet this demand. An overestimation of capacity may result in an inefficient use of space, while underestimating capacity may result in inadequate water supply during peak periods.

Piping and Fittings

The piping and fittings used for a rainwater harvesting system should be chosen carefully in order to ensure maximum efficiency and long-term reliability. The pipe size should be large enough so that it can accommodate the expected flow rate, while being small enough so as not to exceed any local regulations. Additionally, all fittings should meet local requirements and codes and should be made from durable materials such as stainless steel or brass.

Treatment System

It is important to consider a treatment system when designing a rainwater harvesting system in order to ensure safe drinking water quality. Depending on the intended use of the harvested water, an appropriate filtration or disinfection system may need to be incorporated into the design. This could include sediment filters, ultraviolet light systems, chemical treatments or activated carbon filters.


Regular maintenance is essential for any rainwater harvesting system in order to maintain its efficiency and reliability over time. This includes checking all pipes and fittings for leaks or blockages, inspecting storage tanks for cracks or other damage, and ensuring that treatment systems are operating correctly. Additionally, any accumulated sediment or debris must be regularly removed from tanks or filters in order to prevent contamination.

Location and Size of the Storage Container

The size and location of a storage container can vary depending on the purpose it will be used for. For example, if you need to store large items like furniture or bulky boxes, you may require a larger container than if you are storing smaller items like documents or clothing. The location of the container is also important; if it is located in an area that is prone to extreme weather, such as high winds or heavy rain, then a more secure container may be necessary.

When selecting a storage container, it is important to consider the size and location of the space available for storing your items. If you have limited space for your storage container, then opting for a smaller size can save you money and space. However, if you are storing larger items like furniture or appliances, then a larger storage container may be necessary. Additionally, it is important to consider the type of materials that will be stored in the container; some materials are more sensitive to changes in temperature and humidity than others.

Finally, when choosing the location for your storage container, consider factors such as access to power sources and security measures. If your items require electricity or heating/cooling systems, then having access to these power sources would be necessary for their proper functioning. Additionally, security measures such as CCTV cameras and locks should also be taken into account when selecting a storage container location.
