Intelligent Water Distribution & Analytics Platform
Executive Summary
A water utility was losing over a fifth of treated water to leaks and unbilled consumption, with non-revenue water eroding margins and stressing supply. Leaks surfaced only when they became visible; pressure was managed conservatively, wasting energy and stressing pipes; and quality monitoring relied on infrequent manual samples.
Tech4Biz engineered an Intelligent Water Distribution & Analytics Platform: district-metered sensing, edge leak inference, a hydraulic digital twin, AI leak localization and NRW analytics, continuous quality monitoring, and predictive asset maintenance, integrated with GIS, SCADA, CIS, and CMMS, backed by a reference multi-probe sensor node.
This document covers the problem, the engineered solution, the reference sensor hardware, operator screens, and measurable outcomes.
Problem Statement
- High non-revenue water : real losses from leaks plus apparent losses from metering and theft.
- Late leak detection : bursts found by surface visibility, not sensors; long run-times before repair.
- Conservative pressure : over-pressurized zones wasting energy and accelerating pipe fatigue.
- Infrequent quality checks : manual grab samples left gaps in compliance evidence.
- Reactive asset maintenance : pump and valve failures with no early warning.
- Siloed systems : telemetry disconnected from GIS, billing, and work management.
The Engineered Solution
A custom platform combining IoT sensing, edge analytics, a hydraulic twin, AI, and enterprise integration. Four layers:
Field / Sensor Layer
- Ultrasonic/mag flow meters, pressure sensors, quality probes (pH, turbidity, chlorine, conductivity), and acoustic leak loggers across district metered areas.
Edge / Comms Layer — T4B-WTR Sensor Node
- Multi-probe acquisition with edge burst detection, NB-IoT/LoRaWAN comms, and multi-year battery, plus SCADA/RTU for pump and valve control.
Core / Analytics Layer
- Time-series platform, hydraulic digital twin, AI leak localization and NRW analytics, quality compliance engine, pressure management, and predictive asset maintenance.
Applications & Integration Layer
- NRW console, quality dashboard, field app, and customer portal over REST/MQTT/Kafka, integrated with CIS, billing, GIS, SCADA, CMMS, and regulatory reporting.
Reference Hardware Design
The field edge runs on a reference multi-probe sensor node engineered by Tech4Biz, presented as an engineered reference design for deployment on certified field hardware.
Water Sensor Node — T4B-WTR-SN-R1
- Ultra-low-power MCU — ARM Cortex-M with edge burst inference and a secure element.
- Flow Interface — ultrasonic time-of-flight plus pulse and 4-20mA inputs.
- Pressure AFE — 0-16 bar, 24-bit, with 100Hz transient capture for water-hammer events.
- Quality Probes — pH, turbidity, chlorine, conductivity, and temperature.
- Acoustic Sensor — leak-noise capture, correlation-ready for pinpointing.
- Comms — NB-IoT / LoRaWAN with cellular fallback; 5-10 year Li-SOCl2 battery.
- Logger / NVM — store-and-forward in an IP68 buried/chamber enclosure.
Operator Applications
NRW / Leak Operations Console
Non-revenue water and active-leak KPIs, a correlation-based leak event table with confidence and excess flow, minimum-night-flow trending, a monthly water balance, and a work-order log for dispatch and repair.
Water Quality Dashboard
Live parameter gauges (chlorine, turbidity, pH, conductivity, temperature, TDS) against limits, a quality event log, and a rolling regulatory-compliance summary with auto-reporting.
Business Outcomes
Representative outcome targets delivered by the platform:
| Metric | Before | After |
|---|---|---|
| Non-revenue water | High, undiagnosed | Reduced via analytics |
| Leak detection | Surface-visible only | Sensor + correlation |
| Leak run-time | Days to weeks | Hours to days |
| Pressure management | Conservative | PRV-optimized |
| Quality monitoring | Manual grab samples | Continuous + auto-report |
| Asset maintenance | Reactive | Predictive |
| System integration | Siloed | GIS/SCADA/CIS/CMMS |
Additonal benefits
- Lower operational and energy cost through optimized pressure and pumping.
- Improved regulatory compliance with continuous evidence and auto-reporting.
- Extended asset life and fewer emergency repairs.
- Sustainable water resource management and reduced loss.
