From Online Water Quality Monitoring and Groundwater Sensing to full-scale SCADA & Telemetry integrations — Drexel Electronics delivers ISO & TUV-certified solutions that keep water infrastructure safe, compliant, and efficient.
Every solution below is engineered for Indian regulatory standards and Delhi's water-infrastructure demands — from municipal treatment plants to private industrial units.
Continuous, real-time measurement of critical parameters — BOD, COD, TSS, pH, TDS, Dissolved Oxygen, Turbidity, and more — using both probe-based and extractive-assembly sensors. Data streams live to cloud servers and CPCB-compliant portals.
Explore Product →Compliant with the Gazette of India (24 Sept 2020) mandate requiring bore-well level and quality tracking. Drexel integrates with your existing flow meters & level sensors, or supplies a turnkey new system — at significantly reduced cost.
Explore Product →Purpose-built for municipal and private drinking-water networks, these systems track Residual Chlorine, Hardness, Salinity, Orthophosphate, and Temperature in real time — ensuring end-consumer safety across Delhi's supply chain.
Request a Proposal →End-to-end Supervisory Control & Data Acquisition: real-time pump & valve control, chemical dosing automation, sludge-level management, alarm notification, and compliance-ready data logging — all accessible from a single HMI dashboard.
Explore Product →Wireless remote monitoring across dispersed water assets — pump stations, reservoirs, and distribution nodes. Supports cellular, radio, and hybrid communication with store-and-forward capability for uninterrupted data capture.
Explore Product →Fully integrated PLC-based control paired with SCADA supervisory layers for water & wastewater plants. Covers pump sequencing, filter backwash cycles, chemical feed control, and scalable future expansion.
Explore Product →Automated continuous sampling, analysis, and cleaning cycles for ETP and STP outlets. UV spectrophotometer-based detection flags non-compliant discharge before it leaves your facility — protecting both the environment and your license.
Explore Product →Automated report generation aligned with CPCB & SPCB norms. Timestamped data exports, exceedance alerts, and audit-ready logs simplify regulatory submissions and reduce manual effort.
Learn More →Backed by over three decades of engineering heritage — from hydro-turbine commissioning to modern IoT-based environmental monitoring — Drexel combines deep domain expertise with certified manufacturing quality.
Over 1,000 monitoring systems successfully installed and commissioned across India, including 125+ STPs and 195+ ETPs.
Every system is configurable to your exact operational parameters, sensor types, communication protocols, and reporting requirements.
Drexel systems interface with your existing flow meters, level sensors, and SCADA platforms — no rip-and-replace needed.
Dedicated service engineers and an always-on remote monitoring desk ensure uptime and fast fault resolution.
On-site installation, commissioning, and maintenance across Delhi and surrounding NCR districts.
Every product ships with full traceability documentation and is manufactured to the standards shown below.
Our multi-parameter sensor suites cover the full spectrum required by Indian environmental and drinking-water regulations.

Beyond equipment supply, Drexel provides turnkey project management — from requirement scoping through to commissioning and long-term maintenance.
Factory-to-site logistics, civil & electrical coordination, and full commissioning handled by Drexel's certified field engineers. Includes sensor calibration, HMI configuration, and live data verification before handover.
Seamless integration of water, air, and noise monitoring streams into a unified SCADA platform. Ideal for large industrial campuses or municipal bodies managing multiple compliance obligations simultaneously.
Feasibility studies, technology selection, system architecture design, and vendor-neutral benchmarking for new or upgraded water & wastewater treatment facilities across Delhi NCR.
Real feedback from organisations relying on Drexel systems for day-to-day operations.
"Drexel's SCADA system transformed our STP operations. Real-time alerts and automated dosing cut our manual labour by nearly 40 %."
"From groundwater compliance to effluent reporting, Drexel handled everything end-to-end. The after-sales support is outstanding."
"The telemetry system gives us full visibility of our remote pump stations without a single site visit. Incredibly reliable."
