Rainwater harvesting is the utilization of scientific techniques to collect and store rainfall.  It involves the collection of water from the surfaces that rain has fallen upon. The harvested water is filtered and subsequently used for both domestic and commercial purposes. Rainwater harvesting has been practiced since ancient times. New innovative methods have emerged as a result of technological advancements. Such methods have played a considerable role towards water conversation.

Rainwater harvesting is especially essential in arid areas, providing simple and cost-effective solutions for meeting water requirements. While water shortages may be sometimes inevitable, rainwater harvesting systems help people to prepare sufficiently for the eventuality. Rainwater harvesting is a cheap and more reliable alternative to traditional water supply methods. It is the most effective method of conserving water, collecting rainwater into storage tanks to prevent wastage.

Rainwater harvesting systems are most commonly used in metropolitan cities. The systems boost water security and improve the floral system as a whole. Rain water harvesting also prevents erosion thus helping maintain the top layer of the soil. Floods are a significant menace, especially in populated areas. Rainwater harvesting reduces flooding, especially on roads.

A functional storage system is the most critical aspect of rainwater harvesting. The size and design of storage systems depend on the amount of water to be stored. Water harvesting experts carry out sufficient consultation and planning before design and installation of a storage system in a particular location. Storage systems should be properly installed and sealed to avoid leaks. Chlorine is efficient in treating harvested water and keeping it clean.  Barrels and slumps are commonly used to collect rainwater before storage.

Areas that receive direct rainfall such as paved areas and footpaths can act as catchments for rainwater harvesting systems. Rooftops are the most suitable catchment areas due to the generation of a large coefficient of water run-off. Also, there is a minimal chance of water contamination. Properly designed water harvesting systems can reduce water bills by as much as 50%.

Conveyance systems for the rainwater harvesting system collect the water from the catchment areas and facilitate flow to the storage tank. Rain gutters and downpipes should be appropriately designed and constructed to avoid water loss within the rainwater harvesting system.

While water shortages may be sometimes inevitable, rainwater harvesting systems help people to prepare sufficiently for the eventuality. Many businesses have adopted the systems to be self-reliant. Governments across the world have also rolled out efforts encouraging adoption of green practices, such as rainwater harvesting, to boost efficiency. Working with trained professionals helps in the installation of rainwater harvesting systems that are tailored to your needs. Most rainwater harvesting systems are highly functional and require close to zero in maintenance costs. They can be designed to boost watering needs for whole house and even irrigate surrounding landscape.
