During the historical period, growth was driven by rapid urbanization, heightened demand for sustainable water management, greater consumer interest in eco-friendly solutions, expanded installation of greywater recycling systems, and growing awareness of freshwater scarcity.

The smart home greywater sensor market size is expected to see rapid growth in the next few years. It will grow to $1.73 billion in 2029 at a compound annual growth rate (CAGR) of 15.6%. In the forecast period, growth is expected to be driven by increasing demand for automated greywater monitoring, heightened awareness of environmental sustainability, expansion of smart city initiatives, the need for more efficient water resource management, and rising consumer interest in home automation. Key trends include improvements in sensor accuracy and reliability, innovations in wireless communication standards, development of low-power sensor technologies, advancements in real-time water quality monitoring, and the introduction of modular sensor designs.

The rising interest in smart home solutions is expected to drive the growth of the smart home greywater sensor market. Smart home solutions consist of interconnected devices and systems that allow residents to monitor, control, and automate household functions such as lighting, security, climate control, and water usage via digital platforms. The growth of smart home solutions is driven by consumer demand for automation, which enhances convenience and optimizes resource management. Smart home greywater sensors support these systems by monitoring and managing wastewater reuse, improving water efficiency while integrating with home automation networks. For example, in February 2025, Ubisense, a UK-based software company, reported that connected Internet of Things (IoT) devices reached 16.6 billion in 2023, a 15% increase from 2022.

Companies in the smart home greywater sensor market are focusing on advanced solutions, such as filtration systems with smart maintenance, to improve water quality monitoring, extend system lifespan, and enhance household water efficiency. Advanced filtration with smart maintenance refers to setups that remove impurities while incorporating automated maintenance features. For instance, in April 2022, SDS, a UK-based water reuse technology company, launched a prefabricated, skid-mounted greywater recycling system for smaller buildings such as hotels, residential units, and commercial spaces. The system offers a fully automated, on-demand treatment process, using a two-stage treatment with cartridge filters followed by nanofiltration, both featuring automatic backwash self-cleaning to maintain consistent water quality.

In May 2025, Belkin International Inc., a US-based consumer electronics company, acquired Phyn LLC for $24.9 million. This acquisition provides Phyn with strategic support to expand its market presence and accelerate adoption of smart water management solutions. Phyn LLC, a US-based company, specializes in intelligent water systems focused on leak detection and water monitoring using ultrasonic sensors and advanced artificial intelligence (AI).

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the utilities sector, particularly in power generation, grid infrastructure, and renewable energy projects. Higher duties on imported equipment such as turbines, transformers, solar panels, and battery storage systems have increased capital and operational costs for utility providers, forcing them to reconsider project timelines or pass on expenses to consumers through higher energy rates. The water and waste management segments are also affected, with tariffs driving up the cost of essential machinery, piping, and treatment technologies. Additionally, retaliatory tariffs have disrupted global supply chains for critical raw materials like rare earth metals used in clean energy technologies, further complicating the transition to sustainable energy sources. The sector must now prioritize domestic sourcing, digitalization, and efficiency-driven innovations to manage escalating costs while ensuring energy security and regulatory compliance.

A smart home greywater sensor is a sophisticated device integrated into residential water systems that continuously monitors the quality, flow, and temperature of greywater. Its function is to support safe and efficient reuse of greywater for non-potable purposes such as irrigation, toilet flushing, and laundry, promoting water conservation within smart home environments.

The primary types of smart home greywater sensors include ultrasonic sensors, conductivity sensors, optical sensors, and others. Ultrasonic sensors operate using high-frequency sound waves to measure distance, detect presence, or track movement by calculating the time taken for the waves to reflect back. These sensors can be connected via wired or wireless systems. They are applied in residential, commercial, and industrial settings, serving end users such as individual households, apartments, hotels, hospitals, and more.
