According to a research report published by Decisions Advisors, The Australia Rainwater Harvesting Market Size is Anticipated to Reach USD 89.7 Million by 2035, Growing at a CAGR of 5.42% from 2025 to 2035. The rainwater harvesting market in Australia is driven by worsening water scarcity, strict government incentives, and growing sustainability goals. Increasing environmental awareness, climate change impacts, and rising adoption across residential, commercial, and agricultural sectors to reduce water costs and improve self-sufficiency further boost demand.

Market Overview

The rainwater harvesting market consists of solutions, products, and services that provide a range of options to collect, store, filter, and use rainwater for many different uses. The main goal of the rainwater harvesting market is to decrease the need for traditional types of water sources, promote cost-effective methods to conserve water, and create long-term sustainable sources of water in the Residential, Commercial, Industrial, and Agricultural sectors. Water scarcity, urbanization, and sustainability goals are driving Australian households, businesses, and farms to invest in rainwater capture and reuse systems, which will produce increasingly strong competition in the market for rainwater harvesting in Australia. Additionally, buildings can reduce their reliance on municipal water supplies by using rainwater for cooling systems, irrigation, and toilet flushing, which saves money and protects vital water resources. For instance, in order to guarantee correct installation and promote adoption in construction projects, Western Australia's Department of Energy, Mines, Industry Regulation, and Safety stated in June 2024 that new licensing criteria for rainwater system installers will take effect on February 10, 2025. As a result, improved opportunities are becoming available in developing new housing sites, developing large commercial rooftops and green building applications, as well as agriculture and agricultural markets. In addition, the growing reliance on intelligent water management systems shows a national attempt to combine sustainability with practical system maintenance and operational efficiency, which is driving the market.
