Market Segmentation

Rainwater harvesting is referred to as a method of collecting and storing water to be used in the future. The rainwater may be stored in natural reservoirs or tanks where the water is then redirected into a well or borehole. This water is used for different purposes, such as gardening or irrigation. After proper treatment of this water, it may also be used in households as high-quality drinking water. It not only decreases urban flooding and soil erosion but also ensures water availability in water-scarce areas.

The global rainwater harvesting market is divided on the basis of the harvesting method into:

• Above Ground
• Underground

Based on the end-use, the industry has been categorised into:

• Commercial
• Residential
• Industrial

Based on the region, the industry has been categorised into:

• North America
• Europe
• Asia Pacific
• Latin America
• Middle East and Africa

Market Analysis 

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.
