Rapid urbanization, aging infrastructure, climate change, and growing water demand threaten the sustainability of urban water supply systems worldwide. This paper reviews contemporary approaches to creating resilient, efficient, and sustainable urban water supplies. It synthesizes advances in Integrated Urban Water Management (IUWM), demand management (including non-revenue water reduction), nature-based solutions (rainwater and stormwater harvesting, green infrastructure), wastewater reuse, and digitalization (Water 4.0). A conceptual framework combining decentralized and centralized assets, smart monitoring, finance mechanisms, and participatory governance is proposed. The paper discusses practical implementation challenges and policy recommendations to move cities toward sustainable water security. Key findings highlight that combining demand-side measures (NRW reduction, pricing, conservation) with supply diversification (harvesting, reuse, aquifer recharge) and digital asset management delivers the best resilience and economic outcomes
