The European E²STORMED project has the objective of contributing to improved management of stormwater and energy efficiency through the promotion of sustainable drainage systems (SuDS) in Mediterranean cities. For this purpose, a decision support tool has been developed to enable hydraulic and economic decision-making criteria to be complemented with energy, environmental and social criteria.

Water management is amongst the municipal areas with the highest energy consumption and can account for as much as 35% of total municipal consumption. For example, in the city of Valencia, energy consumption associated with water supply and sewerage systems accounts for around 26% of total energy consumption in the municipality. Therefore, it is to be expected that improved energy efficiency in urban water cycle management will result in a significant reduction in municipal energy consumption.


Moreover, when a rural area is urbanised, the impermeable surface area usually increases, land is levelled off and infiltration processes decrease. This causes the peak flow and volume of runoff to increase, which in combined sewer systems means that high volumes of water are received by wastewater treatment plants. In many cases, this water cannot be treated and the mix of stormwater and wastewater is discharged directly into the natural receiving environment.

The European E²STORMED project aims to improve water management and energy efficiency in the urban water cycle and in buildings, through the promotion of the use of innovative stormwater solutions such as Sustainable Drainage Systems (SuDS) in Mediterranean cities. SuDS are infrastructures that seek to reproduce as faithfully as possible the natural water cycle in heavily anthropized urban areas, in terms of both quantity and quality of runoff (reducing volumes of runoff generated and improving its quality). They seek to achieve this whilst at the same time optimising landscaping integration, and the social and environmental value of these initiatives.
