The technique of collecting, purifying, and storing rainwater from different surfaces above ground that can be utilized for different applications is known as rainwater harvesting. These technique helps to restore the level of groundwater and balance the environmental concerns over water.

The water collected from the rain can be utilized for washing machines, watering livestock, toilet flushing, and irrigation of gardens and crops. Both urban dwellers with access to running municipal water and residents of more rural areas who might not have access to a sufficient water supply can harvest and use rainwater. Rooftop and surface-based rainwater harvesting are the two types of rainwater collection techniques with the advantage of saving money and resources.

Consumption Analysis of Rainwater Harvesting Systems from 2017 to 2022 Vs Market Outlook for 2023 to 2033

The Rainwater Harvesting System Market has historically increased between 2017 and 2022 at a CAGR of about 3.9%, with the U. S., China, and Germany holding sizable market shares.

In recent years, as a response to the worldwide water issue, the adoption of such systems, particularly in commercial and industrial applications, has expanded. Additionally, the rules governing the collection of rainwater for uses other than potable ones have accelerated the uptake of these systems in private residences throughout the growing urban environment.

Alternative water conservation strategies are being developed around the world as a result of rising water demand, declining freshwater supplies, and industrial water users that have severely exhausted the world's water resources. Although water usage can be improved, there will still be an increase in demand for water as almost every industrial sector grows. According to Persistence Market Research, the global market for rainwater harvesting would grow at a CAGR of more than 6.9% from 2017 to 2033.

What are the restraints for the Rainwater Harvesting System Market growth?

"The Dearth of Skilled Professionals & High Cost of Training"

Even though rainwater collection is a practical technique for areas with limited water supply, it has several integrations and implementation issues. The implementation and integration of such systems specifically demand a thorough investigation of their operational viability in the region where they are implanted. Frequently, the equipment used is either too expensive or insufficient to meet the needs of the area.

Sometimes there is a lack of user acceptance, enthusiasm, and involvement, which has a detrimental effect on the market. Hydrological data and knowledge are insufficient for confident system planning, design, and implementation. Additionally, socioeconomic problems like unemployment and land tenure are generally underestimated. People typically lack or have an outdated understanding regarding rainwater harvesting and usage, which prevents them from taking full advantage of rainwater resources.

What are the Key Opportunities for Rainwater Harvesting Manufacturers?

Existing water resources are under stress due to the growing worldwide concern over limited water supplies. It applies to the entire world, not just certain geographical areas or nations. To encourage end users to conserve water by installing rainwater harvesting systems, governments in developing countries have introduced a number of programs and activities on a local and large scale. These programs can improve knowledge of this important component of water consumption and collection. In regions with moderate to heavy rainfall, there is a great need for rainwater harvesting. Due to the high water usage in these applications, adoption in commercial and industrial settings is rapidly increasing. These elements generate a wide range of possible opportunities for rainwater harvesting suppliers.

Country-wise Analysis

Which is the Most Lucrative Market for Rainwater Harvesting?

The market in the U.K. will experience growth with a CAGR of around 8.1% in the forecast period. In the U.K., there is a high concentration of rainwater harvesting suppliers and distributors. The presence of multiple sales channels is very high compared to other countries and this makes U.K. market lucrative. This has led the country to acquire a larger market share in the European market. There have been notable developments from the supplier side with regard to the new product offerings.

What is the potential for rainwater harvesting in India?

India accounts for roughly one-third of the South Asia-Pacific rainwater harvesting market. India is an agriculture-dominated country with developments in various industrial and commercial sectors that place a high demand for water. A vastly developing commercial sector and ongoing urbanization have led the market in India to grow manifold in the past few years. The ever-growing population in India will seek water in the coming few years, and hence the increasing inclination towards rainwater harvesting is rapid in this country. India is expected to grow significantly in the upcoming year with around 8.8% CAGR in 2023-2033.

Category-wise Insights

Which harvesting method influences the market demand for rainwater harvesting?

The potential for underground rainwater harvesting to develop seems to be quite great as future land use becomes more constrained. Geographical issues, whether they relate to land space or something else, have a big effect on this business. There will be a huge ground surface where installing individual rainwater systems can be difficult as cities grow and commercialization picks up momentum.

Additionally, because these systems are mostly wet systems, subsurface rainwater collection will spread in popularity over the next few years. Over the projected period, from 2023 to 2033, the segment is anticipated to expand at a remarkable CAGR.

Which Type Drives Demand for Rainwater harvesting?

The market for rainwater harvesting is dominated by systems for collecting wet rainfall. End-users prefer wet systems because the water from these systems can be used repeatedly each year. Compared to dry systems, they provide a higher return on investment and can store a significant amount of water without taking up any ground space since they are put underground.

Wet systems can also be used for commercial, industrial, and small- to medium-sized residential projects because they are affordable and practical. There are no additional costs associated with maintaining the system components because these systems only need annual, one-time maintenance in industries. It is a recommended kind for collecting rainwater due to these characteristics.

Which Application of Rain water harvesting is Most Popular?

Though commercial spaces like public institutions, shopping malls, offices, hotels & restaurants, and other hubs have a tendency to use more water for both potable and non-potable purposes, rainwater harvesting in these locations is predicted to increase.

Rainwater harvesting systems can be installed in commercial buildings as a result of urbanisation and a focus on water efficiency. Commercial areas are likely to gain from legislation and regulations pertaining to the installation of these systems as well as raising public awareness.

Competitive Landscape

The leading players in the market for collecting rainwater control are approximately 20–25% of the total market share. Market players have embraced digital technologies in order to stay ahead of the curve and quickly satisfy customer requests. Numerous participants are observing important strategic relationships and cooperative projects.

Some of the key developments are:

  • In April 2018, StormStation, a product by Stormsaver Ltd., was introduced as a retrofit for current structures or uses that are centralized for rainwater gathering. Rainwater storage, management, and pumps are all contained in a single piece of machinery.
  • In March 2021, The building of an integrated water system that will supply clean water to citizens of a city in Vietnam was supported by Watts Water Technologies. The affected area will receive drinkable water thanks to this partnership between Watts Water and the Planet Water Foundation.
