Drinking Water & Water Supply
Municipal & Tap Water Quality Monitoring Solutions
Safeguard drinking water from the treatment plant to the tap — high-precision turbidity, chlorine and pH monitoring that verifies treatment performance and protects public health.
01Definition
What Is Municipal & Tap Water Monitoring?
Municipal and tap water monitoring is the continuous online measurement of key safety parameters — turbidity, disinfectant residual and pH — across the drinking water treatment process and at delivery points, ensuring every liter meets drinking water standards before it reaches consumers.
02Your Challenges
Customer Challenges
A compromised filter can pass particles and pathogens. Low-range turbidity is the earliest, most sensitive indicator of filter integrity — but only if measurement stays accurate below 0.1 NTU.
Too little chlorine risks microbial regrowth in the network; too much creates taste complaints and disinfection byproducts. Continuous residual measurement keeps dosing in the safe band.
Storm events and algal seasons change turbidity and pH within hours. Treatment processes need real-time data to adjust coagulation and protect finished water quality.
Utilities must demonstrate continuous compliance to regulators — occasional grab samples leave gaps that continuous, time-stamped online records close.
03What to Measure
Monitoring Parameters & Their Significance
What to measure at each monitoring point — and why it matters for your process.
| Monitoring Point | Parameters | Significance |
|---|---|---|
| Raw water intake | Turbidity, pH | Source water quality assessment and early warning for treatment process protection |
| Coagulation & sedimentation | pH, turbidity | Coagulant dosing optimization and settling performance verification |
| Filtration | Low-range turbidity | Filter integrity verification and breakthrough early warning — the critical barrier control point |
| Clearwell & finished water | Turbidity, free chlorine, pH | Final quality verification before water leaves the plant |
| Pump house & delivery | Free chlorine, turbidity, pH | Delivery quality assurance into the distribution network |

05What You Gain
Customer Benefits
Continuous turbidity and chlorine records provide defensible evidence of treatment performance for regulators and utility management.
Real-time pH and turbidity data guides coagulant and disinfectant dosing — improving quality stability while cutting chemical consumption.
Filter breakthrough and residual loss are detected in minutes, giving operators time to act before water quality is affected.
06Proven in the Field
Project References
All case studies
The plant's raw water comes from an upstream reservoir whose quality swings constantly: sediment wash-in from rainstorms, summer algae blooms and organic-matter spikes, drought-period changes. Worse, by the time abnormal water reached the plant intake and was detected, several hours had already passed — the best window for response was gone.
The upgraded plant demanded high accuracy on difficult measurements — low-turbidity drinking water and residual chlorine among them — with instruments that integrate stably into the plant's automation system. Site conditions threw up real problems too, such as abnormal inlet flow conditions, and the schedule required fast technical response and on-site problem solving.
A surface water plant has many treatment stages, and running them on operator experience alone leaves blind spots: filter backwash timing, sedimentation-basin sludge discharge and disinfectant dosing could not be adjusted dynamically against actual water conditions, risking off-spec finished water.
