Water Supply Modernization for GRES Power Plant - Zero-Loss Infrastructure Upgrade

Challenge: Aging Infrastructure, Rising Losses, Expansion Demands

The Haranor GRES Power Plant water supply network faced a triple infrastructure crisis. Decades of continuous operation had corroded the original metal pipe system, creating persistent leaks that wasted thousands of cubic meters annually while driving up electricity costs for circulation pumping. The operator required uninterrupted water supply for both the power plant’s critical cooling and safety systems and the surrounding industrial and residential communities.

Adding urgency: the facility planned construction of 460 MW of new generating capacity by 2029, requiring water infrastructure capable of supporting significantly increased demand without the reliability risks posed by aging, leaking pipes.

The existing system could not reliably support these objectives. Unplanned leaks caused operational disruptions, elevated hydraulic resistance in corroded pipes wasted energy, and aging metal infrastructure offered no foundation for future expansion.

Solution: Comprehensive PE Pipe Replacement and System Modernization

Alan Apire engineered a complete technical overhaul of the water supply network, replacing the corroded metal pipe infrastructure with modern polyethylene (PE) piping and advanced system controls. The solution focused on three core objectives:

Eliminating Unproductive Losses - PE pipe networks achieve near-perfect integrity with zero leaks. By replacing the corroded metal system completely, we removed the source of unproductive water waste and stabilized supply volumes.

Energy Cost Reduction - PE pipes offer substantially lower hydraulic resistance compared to corroded metal, requiring less pumping energy to deliver the same water flow. This directly reduces electricity consumption and operational costs.

Safe, Pure Water Delivery - Polyethylene pipes are chemically inert and food-grade safe, protecting water quality without requiring chemical treatments, a critical requirement for both industrial processes and community drinking water standards.

Future-Proof Capacity - The modernized system was engineered and constructed to accommodate the 460 MW expansion, with pipe sizing, pressure regulation, and infrastructure layout designed for significantly higher throughput without requiring complete redesign.

The implementation required careful coordination with ongoing power plant operations, phased pipe replacement to maintain continuous supply, and integration of modern pressure regulation and monitoring systems throughout the network.

Results: Operational Transformation and Sustainability

The completed water supply modernization delivered extraordinary operational improvements:

Zero Unproductive Water Loss - Elimination of all leaks through complete PE pipe replacement transformed water supply from a leaking, inefficient system to a tight, reliable infrastructure.

Measurable Electricity Cost Reduction - Lower hydraulic resistance in modern pipes directly decreased pumping energy requirements, delivering substantial annual savings in operational electricity costs.

Eliminated Emergency Repairs - The new infrastructure eliminated the emergency repair cycle that had characterized the aging metal system, transforming maintenance from reactive crisis response to planned, predictable operations.

Stable Supply for All Users - Uninterrupted water availability now supports the power plant’s critical thermal and safety systems while reliably serving industrial processes and community water needs without seasonal or operational constraints.

Industrial-Grade Water Quality - PE infrastructure delivers safe, chemically inert water meeting the highest standards for power plant processes and potable use, removing water quality as an operational concern.

Ready for 460 MW Expansion - The modernized infrastructure is engineered and built to support the planned 460 MW new generating capacity without requiring additional major overhaul or replacement of foundation systems.

This project demonstrates how strategic infrastructure renewal eliminates chronic inefficiencies, reduces operational costs, improves reliability, and creates the foundation for industrial growth and community development.
