Rainwater Harvesting Systems Global Market Report 2024

The rainwater harvesting systems market size has grown strongly in recent years. It will grow from $1.78 billion in 2023 to $1.94 billion in 2024 at a compound annual growth rate (CAGR) of 8.8%. The expansion observed in the historic period can be attributed to several factors, including growing awareness about the importance of water conservation, increasing urbanization leading to higher demand for water management solutions, government regulations promoting sustainable water practices, rising concerns over water scarcity particularly in drought-prone regions, and the adoption of eco-friendly practices by both residential and commercial sectors.

The rainwater harvesting systems market size is expected to see strong growth in the next few years. It will grow to $2.55 billion in 2028 at a compound annual growth rate (CAGR) of 7.1%. In the forecast period, the growth is expected to be driven by several factors, including accelerated urbanization and infrastructure development, the exacerbation of climate change impacts on water availability, increased adoption of green building certifications that mandate rainwater harvesting systems, government incentives and subsidies encouraging the implementation of such solutions, and the expansion of the construction industry, particularly in emerging markets. Major trends anticipated in this period include the integration of rainwater harvesting systems with smart city initiatives, a shift towards decentralized water management solutions, the emergence of modular and scalable rainwater harvesting systems, the development of predictive analytics tools to optimize rainwater collection and usage, and the expansion of the rainwater harvesting market into new sectors such as agriculture and industrial applications.

The anticipated increase in water scarcity is poised to drive the growth of the rainwater harvesting systems market in the foreseeable future. Water scarcity, characterized by insufficient freshwater resources to meet the demands of a specific area's human and environmental needs, is on the rise due to various factors including increasing global demand, climate change, population growth, and inadequate water management practices. Rainwater harvesting systems play a pivotal role in addressing this challenge by significantly enhancing water availability, replenishing local aquifers, mitigating urban flooding, and ensuring water access in regions susceptible to water scarcity. For instance, as reported by the United Nations Educational Scientific and Cultural Organization (UNESCO) in May 2023, a staggering 2 billion people lack access to safe drinking water, while 3.6 billion lack proper sanitation, and it is projected that the urban population facing water scarcity will soar to 1.7 to 2.4 billion people by 2050. Consequently, the escalating water scarcity issue is driving the expansion of the rainwater harvesting systems market.

Key players within the rainwater harvesting systems market are intensifying their efforts to develop advanced solutions and products, such as new residential rainwater harvesting systems, to gain a competitive advantage. These systems are meticulously designed to capture and store rainwater from rooftops or other surfaces for subsequent use in domestic applications, including drinking, washing, and bathing. Typically comprising collection surfaces, conveyance systems, storage volumes, and distribution systems, these innovative solutions offer enhanced usability, compliance, water conservation, cost savings, and environmental sustainability. For instance, in February 2023, Stormsaver Ltd., a leading UK-based rainwater harvesting specialist, introduced two new residential rainwater harvesting systems boasting various capacities and cutting-edge features such as internal break tanks for water safety, Type AB air gaps to prevent backflow, integrated twin booster sets for maintaining water pressure, and durable glass-reinforced plastic (GRP) construction. These technological advancements underscore their suitability for residential applications, contributing significantly to the growth of the rainwater harvesting systems market.

In July 2023, Oldcastle Infrastructure Inc., a prominent US-based building material company, finalized the acquisition of Hydro International Ltd. for an undisclosed sum. This strategic acquisition bolsters Oldcastle's capabilities by expanding its product breadth, market expertise, and innovation potential in providing comprehensive rainwater harvesting solutions. By integrating Hydro International Ltd.'s water management expertise, including rainwater harvesting and storage systems, Oldcastle strengthens its position in addressing critical water treatment needs in the market, further cementing its leadership in the rainwater harvesting systems segment.

Rainwater harvesting systems are infrastructure setups engineered to gather, store, and distribute rainwater for diverse applications including irrigation, landscaping, and household use. They serve as essential tools for sustainable water management, relieving pressure on conventional water reservoirs and curbing stormwater runoff, thereby supporting conservation endeavors.

The primary types of rainwater harvesting systems comprise roof rainwater collection, surface rainwater collection, and hybrid rainwater collection methods. Roof rainwater collection entails capturing and directing rainwater from building roofs into storage units, facilitated by gutters and downspouts for effective water conveyance. Components such as tanks, filtration systems, pumps, and distribution networks are integrated into both new construction and retrofit installations, catering to above-ground and underground harvesting techniques. These systems find applications across residential, commercial, industrial, agricultural, public, and municipal sectors.
