Rainwater Harvesting Market

Rainwater Harvesting Market is expected to exceed the market valuation of more than US$ XX billion in 2027 and is expected to grow at a significant CAGR of XX% during the forecast period (2021-2027). Rainwater harvesting is collecting the run-off from a structure or other impervious surface in order to store it for later use. Traditionally, this involves harvesting the rain from a roof. The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel. Rainwater collection systems can be as simple as collecting rain in a rain barrel or as elaborate as harvesting rainwater into large cisterns to supply your entire household demand.

Rainwater harvesting is becoming a viable alternative for supplying our households and businesses with water. There are many countries such as Germany and Australia where rainwater harvesting is a norm. With growing awareness regarding green building movement, rainwater harvesting systems is expected to significant adoption in coming years.

The collection of rainwater is known by many names throughout the world. It ranges from rainwater collection to rainwater harvesting to rainwater catchment. In addition, terms such as roof water collection or rooftop water collection is also used in other countries

Rainwater harvesting is a viable technology in an urban setting. All that is necessary to take advantage of this resource is to capture the free water falling from the roof and direct it to a rainwater storage tank. By doing this, one can take control of your water supply and replace all or at least a substantial portion of their water needs. Rainwater harvesting systems can be configured to supply the whole house and/or any landscape.

The global rainwater harvesting market is driven by the rapidly increasing global population. This has led to an intensification of the pressure on natural water resources. Consequently, consumers are shifting from natural water resources to the storage of water via various effective means, such as rainwater harvesting, to keep the depletion of groundwater level under check. Moreover, due to the minimum maintenance, easy installation process, and availability in a wide range of tank sizes and types, rainwater harvesting is becoming one of the most popular and adopted water harvesting mechanisms across the globe. Further, governments of several countries are promoting campaigns and initiatives to encourage the adoption of rainwater harvesting in both domestic as well as industrial sectors. They are also offering tax relaxations and incentives to encourage the use of these systems.; for example, the Government of India’s investments into the construction of numerous rainwater harvesting structures in the rural and urban areas of the country, which is expected to assist in an equal distribution of and accessibility to drinking water. Decreasing fresh water is expected to accelerate the industry in the forecast period.

Insights Presented in the Report

“Amongst Harvesting Method, Above Ground segment holds the major share”

Based on Harvesting Method, the Rainwater Harvesting Market is segmented into Above Ground and Below Ground. Above Ground is further segmented into Storage Tank and Ground Surface. Above ground garden rainwater systems allow you to store water in your garden without the need for a big project to install a tank underground. Above ground systems will take up space in your garden, but with a selection of sizes available – from 800 to 4000 litres – there are tanks to fit nearly every outdoor space.

“Amongst Application, Agricultural segment holds the major share”

Based on Application, the Rainwater Harvesting Market is segmented into Commercial, Industrial, Residential, and Agricultural. Rainwater harvesting has agricultural uses. It can be used for watering gardens in our homes and crop plants in agricultural fields. If a patch of land, say of 100 hectares, is treated for rainwater harvesting, this area would have 5 hectare of water bodies and each farmer would have free access and full control over water they require. These reduce the reliance of garden owners and farmers on other sources of water supply, thus saving them money. Furthermore, the use of soft water from rainwater harvesting can help to reduce farmers operating costs.
