INTRODUCTION INTRODUCTION

Some facts

• Energy is the 2nd largest municipal cost after labor costs.

• Water and wastewater facilities are often the largest and most energy‐intensive loads owned and operated by local governments, representing up to 35% of municipal energy use.

• Data on energy consumption in the urban water cycle is very scarce, so it’s very difficult for decision makers to incorporate it in their analysis. INTRODUCTION

The E2Stormed project: origin

• Involvement of 3 partners in previous projects for a better urban water management.

• Weak knowledge in MED cities, where stormwater has been seen as a problem of waste and flood damage control.

• Sustainable Drainge Systems (SuDS) as a more sustainable and energy efficient alternative for urban stormwater management. INTRODUCTION

The E2Stormed project: objectives

• Improve energy efficiency in the urban water cycle and in buildings by promoting the use of innovative storm water solutions such as Sustainable Drainage Systems (SuDS) in Mediterranean cities.

• Identify methods, public policies and exchange experiences to plan and set up “smart cities”initiatives.

• Find out and overcome obstacles and barriers hindering cities to transition.

• A Decision Support Tool (DST) is being developed to include energy efficiency and environmental criteria in urban stormwater management decisions. INTRODUCTION

The E2Stormed project: processes INTRODUCTION

The E2Stormed project: partnership

• 9 entities in 7 European countries

– 2 Universities (UPV Lead Partner)

– 6 pilot case Studies in MED cities

– 1 communication + testing partner

• Total budget 1 745 267 €

• Total ERDF funding 1 103 853 €

• Jan 2013 –Jun 2015 www.e2stormed.eu E²STORMED IMPROVING ENERGY EFFICIENCY IN THE URBAN STORMWATER MANAGEMENT IN MEDITERRANEAN CITIES

SUSTAINABLE DRAINAGE SYSTEMS (SuDS) SUSTAINABLE DRAINAGE SYSTEMS (SuDS)

Original Conventional SuDS

• SuDS: Sustainable Stormwater Management

• On‐site retention, infiltration and water quality improvement

• Imitating original/natural conditions SUSTAINABLE DRAINAGE SYSTEMS (SuDS)

• Currently, knowledge of SuDS in the Mediterranean Region is very weak.

• Some pilot cases with very Vegetated swales good performance from a quality and quantity point of view.

E²STORMED DECISION SUPPORT TOOL E²STORMED DECISION SUPPORT TOOL

• Can be used to compare energy consumption, emissions and costs of different drainage scenarios.

• Includes a catalogue with 20 generic types of drainage infrastructures: conventional and sustainable.

• Flexible for different levels of detail.

• Available for local and regional authorities later this year. E²STORMED DECISION SUPPORT TOOL E²STORMED DECISION SUPPORT TOOL E²STORMED DECISION SUPPORT TOOL E²STORMED DECISION SUPPORT TOOL

Case example: Urban development of 51,200 m² with 66 households and a school. Scenario 2: Development with SuDS E²STORMED DECISION SUPPORT TOOL

For each scenario the costs, benefits, energy consumptions and CO2 emissions are estimated for:

•Construction and maintenance of infrastructures.

•Stormwater treatment and pumping.

•Rainwater harvesting.

•Flood protection.

•Building insulation improvement.

For each scenario, economic, energy and environmental criteria are obtained based on these results. E²STORMED DECISION SUPPORT TOOL www.e2stormed.eu E²STORMED IMPROVING ENERGY EFFICIENCY IN THE URBAN STORMWATER MANAGEMENT IN MEDITERRANEAN CITIES

Regional Working Groups of stakeholders have been created in each Pilot Case. The main tasks of these groups are: •Compile data required for the Pilot Cities to contribute to the development of the Decision Support Tool (DST) adjusted to Mediterranean cities. •Evaluate and comment on the application of the DST in an urban area in the Pilot City. •Communicate and disseminate within their entities and to other stakeholders the conclusions of this project.

A FRAMEWORK FOR TRANSITION THE TRANSITION MANAGEMENT WHEEL

How did we get here? Where are we going? Recognition of the fact that the Realisation that there are newer way water systems are managed and better ways to drain a city in is expensive and inefficient more holistic and integrated way THE TRANSITION MANAGEMENT WHEEL How do we transition from a conventional paradigm to a more sustainable and energy efficient one? THE TRANSITION MANAGEMENT WHEEL TRANSITION ACTIVITIES

1. Establish subject focus and identify stakeholders

2. Organise / facilitate stakeholders

3. Identify problems and issues TRANSITION ACTIVITIES

4. Develop the long‐term integrated vision

5. Develop the Strategic Action Plan

6. Carry out pilot / demonstration activities TRANSITION ACTIVITIES

7. Identify and engage additional parties

8. Process documentation and build capacity

10. Prepare the 9. Evaluate and next turn of the learn wheel PILOT EXAMPLE: BENAGUASIL

CONCLUSION FINAL PROJECT OUTCOMES CONCLUSION

Amin Maalouf (2012)

"the relevant question is not whether our attitudes and behavior have progressed in comparison to those of our ancestors; it is whether they have changed enough to face the enormous challenges of the contemporary world” www.e2stormed.eu E²STORMED IMPROVING ENERGY EFFICIENCY IN THE URBAN STORMWATER MANAGEMENT IN MEDITERRANEAN CITIES
