Abstract	This study explores the optimization of pressure management strategies to achieve a sustainable reduction in Non-Revenue Water (NRW) within the Metro Naga Water District (MNWD). NRW, comprising physical leaks, bursts, and commercial losses, poses a significant threat to water security, financial viability, and service reliability. As global water stress intensifies, the necessity for efficient hydraulic management becomes paramount to ensure equitable distribution and resource conservation. The research employed descriptive-correlational and developmental design. Quantitative data were gathered through a survey of 377 concessionaires using a validated five-point Likert scale (Cronbach’s alpha = 0.980) to assess service quality, management efficiency, and sustainability. Technical analysis involved reviewing MNWD archival data and hydraulic reports to identify high-loss zones. Qualitative insights were obtained through purposive interviews with key management personnel to evaluate the feasibility of the proposed strategic interventions. The findings reveal a direct correlation between stabilized water pressure and increased public trust in utility sustainability. While MNWD demonstrates a strong "Sustainability-First" organizational profile, localized pressure disparities ranging from 0 psi in peripheral areas to high pressure zones, contribute to recurring pipe bursts and leakage. The study concluded that manual hydraulic corrections are insufficient for long-term NRW control. Consequently, a Strategic Action Plan was developed, focusing on "Smart Water" governance. Key recommendations include the integration of District Metered Areas (DMAs) with automated Pressure Reducing Valves (PRVs), real-time digital monitoring, and enhanced community engagement to shift from reactive maintenance to proactive, data-driven pressure management.
