Sustainable Urban Drainage Systems (SUDS) implemented in Gran Canaria to manage stormwater runoff, reduce flood risk, and improve water quality through natural infiltration and filtration processes.

The system integrates green infrastructure with traditional drainage to create a resilient urban water management approach.

The SUDS network is strategically distributed across urban areas of Gran Canaria, targeting flood-prone zones and high-density residential areas to maximize impact and community benefit.
