The Portuguese Environment Agency (APA) has resumed the Albufeira drainage plan, involving a 46 million euro investment to mitigate flood risks in the Algarve region. 

A primary element of the project is the construction of a 1.5-kilometer tunnel, estimated to cost 33 million euros, which will divert local stream flows into the ocean to protect low-lying urban areas. The initiative is funded through the Sustentável 2030 program via the Cohesion Fund. Environment Minister Maria da Graça Carvalho characterized the intervention as a major effort to address flooding in a highly vulnerable area.
