Chlorine Analyzers Waste
6.1 Billion Gallons of
Non-Revenue Water — Every Year
Traditional online chlorine analyzers require between 70,000 and 138,000 gallons of treated, pressurized water annually just to operate. Multiplied across the 29,000+ U.S. water systems using chlorine, this totals over 6.1 billion gallons of non-revenue water lost every year — just to measure chlorine. The Halogen MP5 eliminates this entirely.
The Scale of the Problem
Based on EPA Community Water Systems data: 45,973 systems × 64% using chlorine = 29,423 systems × 3 analyzers per plant = 88,268 analyzers × 70,000 gallons/year = 6,178,771,200 gallons annually.
Why the Waste Stream Creates Real Problems
It's not just about water conservation. The 70,000-gallon annual waste stream from traditional analyzers creates serious operational and infrastructure challenges that go far beyond the cost of the water itself.
Disposal Difficulties
Many sites — especially rural facilities and remote monitoring points — are not equipped to handle the discharge of 70,000+ gallons of wastewater per year. Finding a viable drain point is often impractical or impossible.
Septic System Damage
When analyzer waste is directed into septic systems, the high chlorine content kills the beneficial microorganisms the system depends on — rendering it less effective or causing outright damage over time.
Infrastructure Costs
Some municipalities have reported that installing additional sewer lines to manage analyzer waste streams has cost more than $100,000 — a significant capital expense just to accommodate a sensor.
The Real Cost to Your Utility
Water rates (Tier 2) range from $0.003 to $0.01 per gallon across U.S. municipalities. In areas under drought restrictions where water usage reduction is mandated, the cost of a waste stream goes beyond dollars — it may constitute a compliance issue.
How the Halogen MP5 Solves This
The MP5 is a new paradigm in water quality monitoring. It installs directly in the pipe, requires no sample line or drain, and produces zero waste stream — while measuring five critical water quality parameters simultaneously.
No Waste Stream
The MP5 requires zero discharge. It installs directly in the pipe and reads in-situ — no sample line, no drain, no waste.
NSF-61 Certified
The only amperometric chlorine sensor certified for direct contact with drinking water under NSF/ANSI 61 standards.
Install Anywhere
Flow and pressure independent. Reads accurately at zero flow or 4 m/s velocity. Pressure from 0 to 145 PSI has no effect on accuracy.
$200–$1,400 Saved Per Year
Depending on local water rates (Tier 2: $0.003–$0.01/gallon), utilities save $400–$1,400 per sensor per year in non-revenue water alone.
5 Parameters
Measures free chlorine, monochloramine, pH, conductivity, and temperature — all from a single in-pipe insertion.
6–12 Month Maintenance Intervals
Self-cleaning electrodes and electrochemical cleaning extend calibration intervals dramatically. No membranes to replace, no reagent tubing to swap.
Reagentless
No reagents or monthly tubing changes. Eliminates roughly $1,000/year in consumable costs and the truck rolls required to replenish them.
No Chlorine Memory
If exposed to zero chlorine for hours or days, the MP5 detects residuals immediately when they return. Membrane sensors cannot achieve this without complex ancillary systems.
From the Field
"I did some flow measurements with our reagent DPD system and discovered that we were using 138,000 gallons of water per year. Your system is on a side stream and only uses 14,000 gallons. Our next installation will use your Wet Tap Sensor which has zero waste stream. We've been very happy with the Halogen MP5 sensor, and it has been holding up really well."Christopher AlvaradoLaCumbre Mutual Water Treatment Company
"There are some sites that cannot be monitored due to the need for a waste stream. Halogen MP5 solves this problem."Derwin Dy, P.E.City of Lakewood, California
