Six Billion Gallons Down The Drain, Literally

Conventional chlorine residual monitoring relies heavily on a sample-to-waste design, continuously diverting streams of treated water directly down the drain. Across the water sector, this outdated approach accounts for billions of gallons of lost supply each year. Every gallon discarded carries the embedded expense of energy, treatment chemicals, and operational labor, representing non-revenue water that never reaches a end-user.

For individual treatment facilities and distribution networks, tallying the cumulative volume sent to waste across every monitoring point reveals a significant financial and resource drain. In-line and immersed sensing methods eliminate sample-to-waste streams entirely by taking measurements directly within pipes, clearwells, or tanks. Transitioning away from sample disposal gives utilities total control over an internal water-saving opportunity, preserving finished water and protecting operational revenue.
