Abstract: Urban drainage systems are infrastructures essential in urban areas to control the flooding of roads, properties and infrastructures. A common solution is the storage of the water excess in retention ponds. This work proposes a methodology for the adaptation of energy recovery solutions to drainage systems. The consideration of urban flooding as a problem caused by excess water that can be harvested and re-used rests on the concept of Sustainable Urban Drainage Systems (SUDS) and provides a comprehensive representation of a water-energy nexus for future urban areas. The study comprises an optimization of a case study in a small district area of Lisbon downtown through the use of a micro-hydropower converter–a 5 blade tubular propeller. The methodology included the settlement of a power target demand, the sizing of both the volume and the water height in flood control ponds in order to maximize the energy production and on the control of the water discharge.
