Wasserresilienz in Städten: Leckagen senken, Qualität sichern

Introduction

Urban water systems face rising stress from aging pipes, climate extremes, and contamination risks.

Resilience strategies focus on reducing losses while keeping drinking water quality high.

Key Points

• Non-revenue water is often the largest hidden cost
• Smart metering improves detection and customer transparency
• Water safety plans tie operational monitoring to health outcomes
• Climate adaptation requires redundancy in supply sources
• Public trust depends on clear quality reporting

How To

1) Establish a baseline for leakage and pressure zones

Map district-metered areas, pressure profiles, and non-revenue water rates. A clear baseline shows where losses are most critical.

2) Deploy sensors and analytics for rapid leak detection

Install smart meters, acoustic loggers, and pressure sensors to spot anomalies quickly. Analytics dashboards can cut detection time dramatically.

3) Prioritize pipe renewal based on risk and failure rates

Rank assets by age, material, and break history to build a risk-based renewal plan. Focus first on high-impact segments serving dense populations.

4) Strengthen treatment and monitoring protocols

Update water safety plans and expand monitoring for contaminants and turbidity. Routine audits help ensure compliance and protect public health.

5) Engage residents on conservation and reporting

Use outreach campaigns and easy reporting channels for leaks or quality issues. Public participation can reduce demand and speed up response.

Conclusion

Water resilience is a blend of infrastructure, data, and communication. Cities that reduce losses now can reinvest in long-term system upgrades.
