Municipal Water Supply
Drinking Water Treatment & Distribution Network Monitoring
Application Overview
Municipal water supply systems — from source water intake and treatment to distribution network management — require reliable instrumentation for regulatory compliance, public health protection, and operational efficiency. TL Environment provides metering pumps for disinfectant and coagulant dosing, online sensors for continuous water quality monitoring, and flowmeters for accurate billing and network leak detection.
Key Challenges
- Maintaining disinfectant residual throughout the distribution network
- Compliance with drinking water quality standards (WHO, EPA, EU Directive)
- Accurate flow measurement for billing, water balance, and non-revenue water reduction
- Turbidity monitoring at treatment plant outlets and network monitoring points
- pH control for corrosion prevention in distribution infrastructure
- Remote monitoring and SCADA integration for unattended operation
Key Monitoring Parameters
- Free Chlorine (mg/L)
- pH
- Turbidity (NTU)
- Conductivity / TDS
- Flow Rate (m³/h)
- Pressure (bar)

Process & Instrumentation Overview
Flow measurement at intake; turbidity and conductivity monitoring of raw water quality.
Metering pumps dose coagulants based on raw water turbidity and flow rate.
Turbidity sensors monitor filter outlet quality and trigger backwash cycles.
Metering pumps dose chlorine or NaOCl; chlorine sensors verify residual concentration.
Metering pumps dose fluoride compounds at precise concentrations for dental health programs.
Chlorine, pH, and turbidity sensors at network monitoring points ensure water quality throughout distribution.
