The small scale systems (< 5,000 liters/day) segment is expected to account for 47.7% of the North America greywater recycling system market share in 2026. Small scale systems of less than 5,000 liters per day capacity are chosen since they can handle the relatively low greywater generation volumes of residential buildings, small commercial properties, hotels and institutional facilities without the need for costly infrastructure. Their compact design typically requires less installation area, less pumping and easier plumbing arrangements than bigger systems. This makes them well suited for decentralized water reuse projects and building-level applications. The range of capacity also allows more flexibility in integrating greywater treatment into new construction and certain retrofit projects where space and wastewater volumes are constrained. For instance, Dehoust provides GWR and GWM systems with submerged ultrafiltration for quantities from 300 to 3,000 liters per day, especially for private residential development. The company highlights reuse for toilet flushing, laundry, cleaning and garden irrigation, demonstrating continued development of treatment systems below the 5,000-liter-per-day threshold.

Modular Expandable Systems Dominates the North America Greywater Recycling System Market

The modular expandable systems segment is expected to account for 56.6% of the North America greywater recycling system market share in 2026. Modular expandable systems are increasingly preferred because they allow building owners and developers to increase greywater treatment capacity as water demand and building occupancy grow without replacing the entire installation. Their modular design allows for the installation of further treatment modules, storage units and processing capacity to existing systems, rendering them ideal for residential complexes, hotels, commercial buildings and institutional facilities with shifting demands. This scalability can also help with project planning as it can allow the capacity to be grown over time minimizing the requirement for a large initial installation and helping long term water reuse techniques. On July 6, 2026, Hydraloop introduced a configuration combining its Cascade system with a post-treatment unit that adds buffer storage, boosting and residual disinfection for higher-demand developments.

Market Drivers

• Increasing Water Scarcity: Increasing water scarcity in some parts of North America is prompting residential, commercial and institutional establishments to use greywater recycling systems as an alternate water management solution. Drought conditions and pressure on municipal water supplies in water-stressed areas are particularly increasing the need to reduce the consumption of potable water. Greywater recycling allows for the reuse of treated wastewater from showers, sinks and laundry operations for toilet flushing, irrigation and other non-potable applications. This helps building operators to lower the demand for fresh water and to make better use of the water resources available. On January 23, 2025, H2O innovation announced that it has opened a 9,600-square-foot WaterHub facility at the University of Texas at Austin designed to treat and reuse wastewater onsite and reduce the university’s reliance on potable water by around 40%.
• Rising Adoption Of Green Building Certification Programs: Increase in adoption of green building certification programs is driving developers and building owners to integrate greywater recycling into sustainable building designs. Certification frameworks are increasingly emphasizing water efficiency, conservation and responsible resource management. This provides incentives to projects to incorporate technology that reduce potable water usage and wastewater output. Hence, residential complexes, commercial buildings, hotels, educational facilities and institutional projects aiming at improved environmental performance and certification outcomes are incorporating greywater recycling systems. On April 9, 2026, Kilroy Realty announced that 70% of its portfolio was LEED certified, 59% was ENERGY STAR certified and 48% was Fitwel certified in 2025, with a goal of achieving 85% LEED certification by 2030.

How is Rising Adoption In Multifamily Residential Projects Creating New Growth Opportunities in the North America Greywater Recycling System Market?

Rising adoption in multifamily residential projects is creating growth opportunities because a single greywater recycling installation can capture wastewater from multiple apartments and redirect it toward common-area toilet flushing, landscape irrigation and other non-potable requirements. Developers of high-density apartment complexes can therefore achieve greater water reuse from centralized systems than would typically be possible through individual household installations, while modular treatment configurations allow capacity to be matched with the number of dwelling units and expanded as properties grow. The opportunity is particularly relevant for new multifamily developments in water-stressed areas, where dedicated plumbing can be incorporated during construction, reducing the complexity and cost associated with retrofitting existing buildings. On December 11, 2024, Epic Cleantec announced it will install their OneWater system at Kuilei Place, a 43-story, 1,005 unit multi-family residential building in Honolulu. The system is meant to recycle up to 8.5 million gallons of greywater yearly for toilet flushing and landscape irrigation, and it demonstrates how huge residential projects are becoming major applications for centralized onsite water reuse.

Analyst Opinion (Expert Opinion)

• The future of the industry is expected to move toward building-level water recycling rather than isolated household systems, particularly where new construction allows dedicated greywater plumbing to be incorporated from the design stage. Multifamily residential buildings, student housing and hospitality properties are likely to represent strong opportunities because several units or rooms can feed a centralized treatment system, improving the utilization of recycling equipment and creating a clearer business case for developers.
• The strongest opportunity is expected in modular greywater recycling systems for multifamily residential and hospitality applications in water-stressed U.S. states, particularly projects where separate greywater collection infrastructure can be incorporated during construction. Systems capable of scaling through additional treatment modules, such as Hydraloop's Cascade configuration, are well positioned for these applications because capacity can be matched to project requirements rather than requiring a completely different system for each building size.
• To gain an edge, market players should focus on reducing installation complexity rather than competing only on treatment performance. Manufacturers that combine compact equipment, standardized plumbing requirements, remote diagnostics, certification for North American applications and modular capacity expansion can address several of the practical barriers faced by developers, while partnerships with multifamily developers, architects, plumbing contractors and green-building specialists can help incorporate greywater recycling at the design stage instead of attempting costly retrofits later. Hydraloop's emphasis on recycle-ready plumbing guidance and connected system monitoring illustrates this direction.
