2 Bordeaux Métropole at a glance Capital of Nouvelle Aquitaine region Bordeaux Métropole = Intercommunal structure in charge of: -Economic development -Education -Urbanism -housing -environment -quality of life -water & wastewater -public transportation -roads, parking -etc. Bordeaux 28 municipalities inhabitants (2016) 4 th most populated French Métropole + 6% / year students Top 8 (France)* Top 200 (World)* *Shanghai index PIB: EUR 35 Billion (2013) 2 I

3 A world heritage city 3 I

4 smart, liveable and looking to the future Airbus 380 cockpit World s 1st Ground-level power supply tramway Stadium longest vertical-lift bridge in Europe Resource recovery from waste Smart urban drainage management Heat recovery from wastewater 4 I Megajoule laser Kedge business school Cité du Vin

5 Strategy for water and waste management Growing population : +33% from 2011 to 2020 Climate change Water: ensure safe, sustainable and affordable service Ensure water resource Protect natural environment and biodiversity Develop shared governance Mitigate risks: flooding and pollution Solid waste: restrain annual production : +24 % from 2011 to 2020 Optimize collection and increase the cleanliness feeling Optimize sorting Encourage a zero waste behaviour: pilot zone of incentive tax for 8000 inhabitants following the «pay as you throw» Increase resource recovery from water and waste: electricity, heat, raw material 5 I

6 Bordeaux Métropole and Suez: a long partnership Delegated public service of drinking water (1992) Annual volume produced: 55mn m 3 /year Length of distribution network: 3132 km Investment > Eur 500 Mio Delegated public service of wastewater (1993) Length of sewerage network: 3950 km Annual volume treated: 68mn m 3 /year Investment > Eur 150 Mio BOT of a solid waste treatment & recycling plant (1997) Investment: Eur 100 Mio Sorting plant Energy from waste plant Research & Innovation centre (2011) 30 experts, 6 PhD students, 4 Post-doc Eur 4 M / year Hosted by Bordeaux University Part of SUEZ international network of research and expertise 6 I

7 Best practice 1 Sponge city: dynamic management for protection of aquatic ecosystems and flood prevention

8 A very sensitive sewer system Amphitheatre shape Oceanic climate Garonne river subject to tides (±7 m) Garonne 6 WWTP Total treatment capacity : ~ EH 73% in Louis Fargue and Clos de Hilde Lake of Bordeaux Bordeaux city center 8 I

9 Context 1982 : 2 major floods May 31st : 81 mm in 60 min June 2nd : 44 mm in 54 min Fight against flooding became a major issue Huge investment plan on infrastructures development : 9 I 1 billion / 30 years

10 Sustainable urban stormwater Compulsory for every construction project 10 I

11 Stormwater infrastructure 115 storage tanks (~ 2 Mm 3 ) 30 main tanks (~ 1,5 Mm3) Tunnels up to Ø 4,5 m 60 pumping stations (~ 135 m 3 /s) 11 I

12 Drivers of dynamic management Regulatory: reduce CSO Reduction of annual number of overflows (objective) Public safety: Protection against flooding 2003 (ref) Implementation of AQUADVANCED URBAN DRAINAGE on Louis Fargue catchment 12 I Use storage capacity of tanks and sewers Treat a 1-month rain event Accelerate emptying if necessary

13 Principle of functionning Monitoring Anticipation Dynamic management 20 Rain gauges 1h radar forecast Radar 5 MIN Optimizer Hydraulic model 3 hours hydraulic forecast 100 Network measurements operation strategy Garonne water level Control strategies Pumping stations, gates and tanks 13 I

14 Integrated supervision & control Supervision centre Dynamic control SUEZ Aquadvanced Urbain Drainage 14 I

15 Benefits and key succes factors Benefits Success factors o Integrated and collaborative approach o Know-how of operators: technology alone is not smart! o To realize a real sponge city, the design and planning is not sufficient: sustainable stormwater solutions + storage infrastructure + dynamic management 15 I

16 Protect the aquatic ecosystems against micro-pollutants Characterize pollutions and quantify their impact Develop measurement protocols Diagnosis of micropollutants flows Evaluation of biological impact Identify solutions to reduce micro pollutants inputs Sustainable urbain drainage of stormwater Change behaviour of domestic customers Raise awareness in hospitals and industries, help to change practices Restauration and preservation of aquatic ecosystems Restauration of the ecological continuities, impact studies, Renaturation of water streams Integrated territorial approach 9 partners coordinated by Suez 16 I
