The City of Lagos Extreme Water Events Early Warning System

Project Objective

The project aims to enhance the City of Lagos's capacity for flood risk management by implementing an early warning system (EWS) to be deployed in four communities within Lagos.

Automatic Weather Station equipment will be procured, installed, configured, and commissioned, ensuring seamless integration with existing systems. Additionally, the project will focus on community engagement by establishing local flood monitoring and response teams, ensuring that vulnerable populations are well-informed and prepared during flood events.

Scope of Work

• Assess existing Early Warning System (EWS) infrastructure, deliver inception workshop, finalize workplan, and develop safeguarding risk register.
• Conduct GIS-based flood risk assessment using historical and climate data.
• Map stakeholders, design engagement strategy, pre-identify volunteers, and establish local communication channels.
• Assess six communities and select four priority sites for EWS installation, with needs and gap analysis.
• Purchase, calibrate, and install weather monitoring stations with solar power, backup systems, and integration into ArcGIS and SensorThings.
• Conduct workshops on flood risks, evacuation procedures, and train community-based Flood Monitoring and Response Teams.
• Launch community-led campaigns using CDAs, CBOs, radio, posters, and digital channels (WhatsApp/SMS alerts).
• Set up real-time GSM/LTE data transmission, dashboards, automated alerts, and calibration of thresholds for community notifications.
• Train city officials, hand over community monitoring structures, provide manuals, evaluation framework, and technical documentation.
• Deliver monthly and quarterly system reports, ensure warranty compliance, provide technical support, and implement a sustainability strategy with a 12-month defect liability and maintenance period.
