Water Shortages
Frequent extreme raw water shortages demand maximum delivery efficiency and physical loss reduction.
Optimization of a Water Distribution System
Operational Challenges
Costly Treatment
Specific treatment procedures are expensive, making lost non-revenue water a heavy financial burden.
Pumping Energy
Water transport requires huge amounts of electricity, exposing utilities to volatile energy prices.
Smart Modeling &
Loss Identification
To optimize a water distribution system (WDS), exact parameter knowledge is essential. Physical attributes are directly imported from GIS into EPANET model.
Database:
Uses historical pressure & flow measurements from District Metered Area (DMA) zone inlets.
Water Balance:
Correlates DMA inflows with billed demand to identify physical leakage coefficients.
Advanced Analysis:
Solves complex grey-box mathematical models while honoring strict pressure limits.
Core Optimization Outcomes
Leakage Loss Reduction
Minimizes physical water loss by optimizing valve and pump operations throughout the distribution network
Energy Optimization
Lowers pump electricity costs during peak tariff hours, shifting load intelligently.
Guaranteed Service Pressure
Ensures required delivery pressure at every consumer node, maintaining strict compliance standards.

Advanced Reliability & Safety
Moving Horizon Control (MPC)
Shifts from a rigid 24h plan to a continuous sliding window, reacting dynamically to pipe bursts or sudden demand spikes.
Fallback Safety Layer
Standard protective hysteresis rules stay active in background to prevent unsafe operations during hardware downtime.
Soft-Sensing Technology
Estimates missing telemetry (e.g. broken tank level sensors) automatically using neighboring network sensor nodes.
