Greywater Recycling Systems Market Report 2026

The greywater recycling systems market size has grown rapidly in recent years. It will grow from $1.5 billion in 2025 to $1.67 billion in 2026 at a compound annual growth rate (CAGR) of 11.6%. The growth in the historic period can be attributed to rising water scarcity issues, increasing urbanization and population growth, government regulations on water conservation, advancements in water treatment technologies, growing environmental awareness.

The greywater recycling systems market size is expected to see rapid growth in the next few years. It will grow to $2.59 billion in 2030 at a compound annual growth rate (CAGR) of 11.5%. The growth in the forecast period can be attributed to increasing adoption of smart water management systems, rising demand for sustainable building solutions, technological innovations in membrane and filtration systems, expansion in commercial and industrial applications, integration with smart city infrastructure. Major trends in the forecast period include integration of smart sensors for greywater monitoring, adoption of ai-driven water management systems, implementation of iot-based water recycling solutions, expansion of automated greywater treatment systems, development of eco-friendly and low-energy treatment technologies.

The growing issue of water scarcity is expected to drive the expansion of the greywater recycling systems market in the coming years. Water scarcity occurs when water demand exceeds the available supply in a region, resulting in limited access to water for essential needs. This challenge is intensifying due to climate change, which disrupts precipitation patterns, increases the frequency of droughts, and accelerates evaporation, thereby reducing overall water availability. Greywater recycling systems help address water scarcity by enabling the efficient reuse of wastewater from non-potable sources such as sinks and showers. By treating and repurposing greywater for applications like irrigation and toilet flushing, these systems reduce dependence on freshwater supplies and promote sustainable water use in urban and industrial settings. For example, in August 2025, the World Health Organization (WHO), a Switzerland-based intergovernmental organization, reported that in 2024, approximately 2.1 billion people worldwide lacked access to safely managed drinking water, including 106 million individuals who relied on untreated surface water, underscoring ongoing challenges related to water availability. As a result, increasing water scarcity is a key factor driving 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.
