PROJECT EXECUTIVE SUMMARY
Engineering Overview
Electromechanical turnkey package for a 40,000 m³/day municipal water intake, filtration, and high-lift pumping scheme providing clean drinking water to over 250,000 residents.
The Challenge
Water hammer shocks on sudden power failure risked catastrophic pipeline rupture, requiring synchronized electrical valve deceleration and automated soft-stop pump sequences.
The Engineering Solution
Implemented multi-motor 450kW Variable Frequency Drive (VFD) panels with built-in surge vessel monitoring and automatic ramp-down algorithms, backed by dual utility power feeders and instant diesel generator changeover.
Key Scope & Technical Deliverables
- 4 x 450kW high-lift centrifugal pump motor drive panels
- Chemical dosing automated control cubicles with pH & turbidity monitoring
- Central SCADA control room with interactive dual-screen mimic console
- Remote GPRS telemetry for 6 regional overhead water storage reservoirs
- Complete facility earthing and surge protection
Project Results & Impact
Capacity
40,000 m³ of clean water treated and pumped daily
Pipeline Protection
Zero hydraulic water hammer incidents recorded since commissioning
