Chlorine Sensors Waste An Estimated 6.1 Billion Gallons Of Non-Revenue Water Every Year

Non-revenue water (NRW) losses pose a significant challenge for utilities, with millions of gallons lost annually through leaks—and less obviously, through chlorine sensor waste streams. Traditional sensors, including DPD and amperometric models, can waste up to 70,000 gallons of treated water per year, per unit. With over 88,000 chlorine analyzers operating in the U.S., this translates to over 6 billion gallons wasted annually. These waste streams also pose operational and environmental challenges, especially when discharged into septic systems or where sewer access is limited.

Enter the Halogen MP-5 sensor, an NSF61-certified innovation originally developed for the U.S. Navy. It uses a membrane-free, self-cleaning, flow-independent design that completely eliminates the need for waste streams. The MP-5 also measures five key parameters (free chlorine, monochloramine, pH, conductivity, temperature), requires no reagents, and can operate maintenance-free for 6–12 months. It installs directly into pipes or tanks without flow or pressure constraints, enabling chlorine monitoring in previously inaccessible areas.

By removing the waste stream and dramatically cutting operational overhead, the MP-5 empowers water utilities to conserve resources, save costs, and achieve greater compliance—all while maintaining accurate, real-time water quality monitoring.
