•Damage claimed after that flood : 6 million Euros!
•If we could cut the runoff by 50% literally no damage at all

Goals:
• local pilot intervention in one of the problematic areas
• Visible result
• Pilot application that will show the way for more similar projects

Administration for Raindrop (or democracy in modern Greece)Administration for Raindrop (or democracy in modern Greece)
Delays:A city in financial difficulties
Payment reimbursement delays from EU (still waiting)The city is not very wealthy
Elections on Oct 2006 - but new Mayor appointed in FebruaryVery close result (0.17%) with final decision in court… 4 months of administrative halt
Actions for solving the problem:Mobilization - The new Mayor took it personally
Meeting in Prague with project partnersMeeting in Rome with the Managing Authority
Results:No funds lostTransfer of funds from 2006 to 2007 (exceptionally)No total delayNo risk for the other project partners and their payments

Retention tank and trough trench:•Discovery of archaeological findings in <2m of depth•Manual work…from the National Archaeological Service•Findings (pottery, skeletons, a well, food storage facilities) were only 2000 years old…and belonged to poor people (no gold!) ==> The site was released after 15 days

The future (Rain Drop: much more than just a drop!) The future (Rain Drop: much more than just a drop!) Big retention schemes are designed in combination with stormwater network:•Reducing runoff discharge compared to “classic network only” from 24-->6m3/s •Diversion of supercritical flow >14m3/s with lateral weir schemes•Tanks ~12m deep with parking above them

The future (Rain Drop: much more than just a drop!) The future (Rain Drop: much more than just a drop!) Authorities are embracing BMPs: Construction of networks will be approved on one condition: Retention to the existing runoff discharge to the rivers (assuming no network at all)
BMPs are emerging: •Acharnai - Agia Anna district, 0.7km2
•Municipality of Ano Liossia, 8km2 of urban space with 30,000 inhabitants•Athens Military hospital extension, 0.1km2
BMPs in the regulatory framework:The Ministry of Environment Planning and Public Works & National Technical University are working on the:
•Overview of the legal framework in the developed countries•A Law Proposal/Draft to include BMPs in SW design and planning nationwide
The future of RainDrop in the context of the new INTERREG:•Experienced, coherent, and successful team•BMPs with a more holistic approach - Include the upstream parts in the design•Climate change…

The Raindrop experience (lessons and the final outcome)The Raindrop experience (lessons and the final outcome)
Experience (or lesson!) No1: Driving in the bumpy road of project implementation…•Delays can happen (we are not UFOs, we are operating in the political and administrative reality)
•Funding reimbursement delays•Delays in works’progress•Political fist fighting
•Delays are not the end of the world (do not panic!)•No need to point fingers among partners•Opportunism (another bad –ism) is not the right way of thinking
Experience (or lesson!) No2: Dealing with the Bosses…Success (or failure) is for everybody …•EU Commission and MA and the JTS are not ruthless queens (on the contrary…)
•We can always talk to them•They are there to listen•They want to help, not to punish!
•Project Partners, Lead Partner, JTS, MA, and the EU Commission are all partners after all•Talking regularly has been a very good medicine to all problems• Communication and transversal information is always welcome MA<->LP <->PP
Experience (or lesson!) No3: EU projects are a great thing!•Multidisciplinary, multinational, multicultural endeavours (Its all about Europe after all) •They are projects providing impetus for change
•Promotion of new ideas and technologies•Promotion of environmentally friendly and technically sound solutions •Shaping the future in our profession

The final outcomes from Raindrop project
•Methodology for Storm Water Management Master Planning•Step by step approach•Based on the principles:
• Maintain as undisturbed as possible the hydrological cycle after the urbanization. •Peak flows and flow volumes will not exceed those before urbanization.
•Fundamentally ecological approach of SWM.
•Guidelines for the selection of BMPs •Advantages / Disadvantages•Relative costs•A straightforward tool without getting into complicated science
