See Your Whole
Distribution System
Continuous water-quality and pressure monitoring, everywhere you need it — so problems show up as they happen, and you have the 24/7 record new state laws require.
The bottom line
Most utilities only check distribution water quality a few times a month, at a handful of sites, by hand. Halogen puts continuous, self-powered sensors throughout your system and streams the results to the cloud — so problems show up as they happen, and you have the 24/7 record new state laws require.
The challenge today
Water leaves your plant in great shape. What happens to it over the miles of pipe, storage tanks and dead ends between the plant and your customers is much harder to see — and today that picture comes almost entirely from manual grab samples. That leaves real blind spots:
Disinfectant residual can dip and recover between samples, and you would never know.
Nitrification in chloraminated systems is usually caught only after it is well underway.
Low residual and stagnant water in dead ends and tanks — the conditions that let bacteria grow — go undetected.
Contamination, backflow and pressure problems can come and go before anyone takes a reading.
New rules are raising the bar
Regulators are moving from "take a sample" to "prove it continuously." New Jersey's S2188 now requires public water systems to hold a minimum residual — at least 0.3 mg/L free chlorine, or 1.0 mg/L monochloramine — throughout the distribution system, with a compliance deadline of August 1, 2026.
New Jersey is a model other states are weighing, and the direction lines up with federal rules already on the books. A weekly grab sample covers less than 0.1% of the year — not enough to prove a residual continuously. Continuous monitoring is the practical answer.
What you can now see and do
| What you get | Why it matters to you |
|---|---|
| Know your residual is holding, everywhere | Catch a residual loss the day it starts, not weeks later at the next sample |
| Get ahead of nitrification | An early warning before nitrite climbs, so you can flush or re-dose in time |
| Meet the new residual rule | Documented proof for NJ S2188, without weekly grab samples |
| See contamination and backflow fast | A water-quality shift plus a low-pressure event at the same spot — data to pinpoint and isolate |
| Find leaks, bursts and pressure problems | Faster response, less water loss, longer main life |
| Keep boil-water notices small | Scope a notice to the affected district and lift it sooner, with data |
| Do more with less chemical and staff time | Lower chemical spend and fewer truck rolls for manual sampling |
Keep boil-water notices small and short
When a main breaks or pressure drops, you often have to issue a boil-water notice. Because it is hard to prove exactly which neighborhoods were affected, the notice frequently covers the whole system and stays in place for days. With sensors throughout your districts, you can show which zone lost pressure and for how long, prove the rest of the system held, and confirm in real time when things are back to normal — for fewer, smaller, shorter notices.
What this means for your utility
Safer water, faster response
Problems surface in hours, not weeks, so you can act before customers are affected.
Compliance you can prove
A continuous record backs up your S2188 residual reporting and helps resolve complaints with data.
Lower cost to operate
Right-size chemical dosing, target flushing and crew visits, and cut back on routine manual sampling.
Coverage where you never had it
Because the sensors need no power or wiring, you can finally monitor the far corners of your system.
Getting started is straightforward
Start with your known problem areas or your S2188 monitoring points, and expand over time. No trenching, reagents, or dedicated power.
