Rainwater harvesting systems are infrastructure designed to collect, store, and distribute rainwater for various purposes, such as irrigation, landscaping, and domestic use. These are utilized primarily for sustainable water management to alleviate strain on traditional water sources and mitigate stormwater runoff, contributing to conservation efforts.
The main types of rainwater harvesting systems are roof rainwater collection, surface rainwater collection, and hybrid rainwater collection. Roof rainwater collection involves capturing and directing rainfall from building roofs into storage units, utilizing gutters and downspouts for efficient water channeling. The components include tanks, filtration systems, pumps, distribution systems, which are installed in new construction, and retrofit types for above-ground and underground harvesting methods. Several applications include residential, commercial, industrial, agricultural, public, and municipal.

The rainwater harvesting systems market size has grown strongly in recent years. It will grow from $1.94 billion in 2024 to $2.1 billion in 2025 at a compound annual growth rate (CAGR) of 8.5%. The growth in the historic period can be attributed to growing awareness about water conservation, increasing urbanization, government regulations promoting sustainable water management practices, rising concerns over water scarcity in drought-prone regions, adoption of eco-friendly practices by 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 $2.7 billion in 2029 at a compound annual growth rate (CAGR) of 6.5%. The growth in the forecast period can be attributed to accelerated urbanization and infrastructure development, intensifying climate change impacts on water availability, increasing adoption of green building certifications requiring rainwater harvesting systems, government incentives and subsidies for implementing rainwater harvesting solutions, expansion of the construction industry particularly in emerging markets. Major trends in the forecast period include integration of rainwater harvesting systems with smart city initiatives, shift towards decentralized water management solutions, emergence of modular and scalable rainwater harvesting systems, development of predictive analytics tools for optimizing rainwater collection and usage, expansion of the rainwater harvesting market into new sectors such as agriculture and industrial applications.
The rising water scarcity is expected to propel the growth of the rainwater harvesting systems market. Water scarcity is the condition where the demand exceeds the available supply, leading to insufficient freshwater resources to meet a specific area's human and environmental needs. Rising water scarcity is driven by increasing global demand, climate change, population growth, and inadequate water management practices. Rainwater harvesting systems address growing water scarcity by substantially augmenting water availability, aiding in replenishing local aquifers, mitigating urban flooding, and guaranteeing water access in areas prone to water scarcity. For instance, in May 2023, according to the United Nations Educational Scientific and Cultural Organization (UNESCO), a France-based specialized agency of the United Nations, 2 billion people lack safe drinking water (26% of the global population), and 3.6 billion lack proper sanitation (46%). Moreover, the urban population facing water scarcity will reach 1.7 to 2.4 billion people in 2050. Therefore, rising water scarcity is driving the growth of the rainwater harvesting systems market.
Major companies operating in the rainwater harvesting systems market are increasing their focus on developing advanced solutions and products, such as new residential rainwater harvesting systems, to gain a competitive edge in the market. These systems are designed to capture and store rainwater from rooftops or other surfaces for later use in domestic applications, such as drinking, washing, and bathing, and typically consist of collection surfaces, conveyance systems, storage volumes, and distribution systems. For instance, in February 2023, Stormsaver Ltd., a UK-based company specializing in rainwater harvesting, launched two new residential rainwater harvesting systems. This system features a variety of capacities, such as an internal break tank for water safety, a Type AB air gap for preventing backflow, an integrated twin booster set for maintaining water pressure, and glass-reinforced plastic (GRP) construction for durability. These technological developments enhance usability and compliance and contribute to water conservation, cost savings, and environmental sustainability in the rainwater harvesting systems market, making them attractive for residential applications.
In July 2023, Oldcastle Infrastructure Inc., a US-based building material company, acquired Hydro International Ltd. for an undisclosed amount. This acquisition brings enhanced product breadth, market expertise, and innovation potential, significantly strengthening Oldcastle's position in providing comprehensive rainwater harvesting solutions and addressing critical water treatment needs in the market. Hydro International Ltd. is a UK-based company that provides water management solutions, including rainwater harvesting and storage systems.
