Greywater Recycling Systems Global Market Report 2025

The greywater recycling systems market size has grown rapidly in recent years. It will grow from $1.35 billion in 2024 to $1.52 billion in 2025 at a compound annual growth rate (CAGR) of 12.3%. The growth during the historic period can be attributed to increasing water scarcity in urban regions, rising awareness of water conservation, government incentives for sustainable plumbing solutions, the high cost of freshwater supply, and growing urbanization.

The greywater recycling systems market size is expected to see rapid growth in the next few years. It will grow to $2.38 billion in 2029 at a compound annual growth rate (CAGR) of 11.9%. The projected growth in the forecast period can be attributed to the growing demand for eco-friendly building solutions, the rising adoption of water reuse technologies, increasing water utility costs, the expansion of green building certifications, and a growing focus on residential water efficiency. Key trends expected during this period include advancements in smart water monitoring systems, the integration of the Internet of Things (IoT) in greywater systems, research and development in compact treatment units, innovations in membrane and filtration technologies, and the development of automated greywater recycling solutions.

The growing issue of water scarcity is expected to drive the expansion of the greywater recycling systems market. Water scarcity occurs when the demand for water exceeds the available supply in a region, leading to insufficient access to essential resources. This issue is exacerbated by climate change, which brings about altered precipitation patterns, more frequent droughts, and increased evaporation, all of which reduce water availability. Greywater recycling systems help alleviate water scarcity by providing efficient methods to reuse wastewater from non-potable sources, such as sinks and showers. These systems reduce the need for freshwater by treating and repurposing greywater for uses such as irrigation and toilet flushing, thereby promoting sustainable water usage in urban and industrial areas. For example, in July 2023, the United Nations reported that in 2022, 2.2 billion people lacked access to safely managed drinking water, with 115 million people relying on surface water sources. Consequently, the increasing water scarcity is fueling the growth of the greywater recycling systems market.

Major players in the greywater recycling systems market are focusing on the development of innovative solutions by integrating smart technologies, such as mobile greywater reuse systems, to provide efficient and sustainable water management solutions in urban areas. The mobile greywater reuse system is a portable unit that treats and recycles greywater on-site for non-potable applications, such as toilet flushing and irrigation, thus promoting sustainable water use. For instance, in May 2024, Nijhuis Saur Industries, a Netherlands-based industrial water company, introduced the Grey Water Treatment 2 solution. This mobile unit enables decentralized greywater treatment and reuse for toilet flushing and irrigation, addressing water management challenges in real estate developments and disaster relief areas. It helps promote sustainable water practices in rapidly growing urban populations.

In May 2023, Coerco, an Australia-based liquid management company, acquired Aquarius Wastewater Systems Pty Ltd. for an undisclosed amount. Through this acquisition, Coerco aims to expand its capabilities in wastewater and greywater treatment solutions, thereby enhancing its product offerings and solidifying its position in the residential, commercial, and industrial water management markets. Aquarius Wastewater Systems Pty Ltd. is an Australian company that specializes in greywater recycling systems.

Greywater recycling systems are water treatment solutions designed to collect, treat, and reuse wastewater from non-toilet sources, such as sinks, showers, and washing machines, to reduce freshwater consumption and wastewater output. These systems are commonly used for applications such as toilet flushing, landscape irrigation, cooling, and industrial processes. By recycling greywater for everyday household needs, these systems help conserve fresh water, reduce overall water usage, and promote sustainability.

The main types of greywater recycling systems are diversion systems and treatment systems. Diversion systems involve methods or mechanisms designed to redirect or separate greywater from other waste streams for treatment and reuse. The available technologies include filtration, biological treatment, chemical treatment, and membrane technologies. These systems are applied across various sectors, including residential, commercial, industrial, and agricultural. Distribution channels for these systems include both online and offline platforms. The primary end users of greywater recycling systems are households, hotels, educational institutions, industrial facilities, and other relevant sectors.
