31. Water Reuse: Solutions For Sustainability, Efficiency, And Resilient Water Systems 10/28/2025

    What is water reuse?

    Water reuse is the process of treating and reclaiming water from various sources for practical purposes, including groundwater recharge, industrial applications, wetland restoration, agricultural irrigation, public access area uses, as well as drinking water applications. By reusing water, communities can reduce dependence on traditional water supplies, avoid costly imported water from 3rd party providers, and improve resilience in water systems. Thanks to progress in water treatment technology, along with economic and regulatory incentives, water recycling has become a cost-effective and sustainable solution to meet the growing demand for highly treated water and overcome supply shortages during droughts.

    There are three primary types of water reuse: Indirect Potable Reuse (IPR), Direct Potable Reuse (DPR), and Non-Potable. In IPR reuse systems, advanced treated water is either injected into an environmental buffer (groundwater, river, or reservoir) before being extracted again for use, whereas DPR is directly blended into the drinking water treatment plant or distribution system. Non-potable water is not intended for human consumption and can be used for irrigation, industrial processes, laundry, or toilet flushing.

    Advanced treatment technologies, such as membrane filtration, reverse osmosis, ultraviolet disinfection, ozonation, and advanced oxidation processes (AOP), play a crucial role in ensuring the quality and safety of reclaimed water.

    Why reuse water? 

    As water scarcity continues to rise, water reuse is an essential strategy for creating a more sustainable future. The use of recycled water reduces the demand for freshwater sources, which are becoming increasingly scarce due to population growth, climate change, and other factors.

    Here are some key benefits of water reuse:

    • Safeguard quality and resilience: Reused water is purified well beyond drinking water standards, improving resilience and ensuring quality for both potable and even non-potable purposes.
    • Uphold safety: Treatment processes like ozone and ultraviolet light can be used to disinfect or break down complex contaminants, ensuring water is pathogen-free and concentrations are below maximum contaminant levels (MCL).
    • Ensure cost savings and efficiency: After treating a waste stream to discharge level, it may require less treatment to bring it to reuse standards, making reuse not only environmentally responsible but also cost-effective in many scenarios and locations.
    • Conserve traditional water supplies: By reusing water, we can lessen our reliance on conventional water resources like rivers, lakes, and aquifers, thereby conserving them for future generations.
    • Reduce carbon footprint: Water reclamation is often more efficient than treating a raw water resource, which can lessen environmental impact.
    • Enable versatility and customization: Advanced treatment systems are tailored to meet specific needs for a variety of sectors, including industrial, urban, agricultural, and public access area uses.

    How to reuse water 

    The major aim of every reuse project is to minimize human health risk associated with the use or consumption of reclaimed water. While the exact treatment requirements depend upon the source water quality and the reuse purpose, to be cost-effective, the treatment must be energy efficient and have a high-water yield.

    An adequate treatment design plan depends on the application the water will be used in. In non-potable applications, normally filtration and disinfection will suffice, while potable reuse generally requires a combination of advanced treatment processes such as membrane filtration, reverse osmosis, disinfection, and/or advanced oxidation.

    Xylem has brands and solutions to fit every stage of the water reuse process: 

    • beginning with the transport of raw sewage and wastewater with Xylem brands like Flygt
       
    • to secondary treatment to remove most dissolved and suspended organic matter and nutrients with brands like Sanitaire and Envirex
    • to tertiary stages that remove residual particulate matter, nutrients, TDS, and nematode eggs with brands like Leopold and Davco
    • along with disinfection and advanced oxidation that inactivates pathogens, and breaks down trace constituents and emerging contaminants of concern with brands like Wedeco, ETS-UV, ATG UV Systems, Pacific Ozone, and Wallace & Tiernan 
    • and finally, digital solutions like YSI, OI Analytical, Xylem Vue that leverage remote monitoring, alerts, and data analytics for proactive and predictive maintenance
