Before use: After Use: Intake Release to environment Treatment Recycling Treatment/regeneration Transport and Storage Urban drainage Distribution Consumption The Urban Water Cycle
4 sources of supply Superficial water from Llobregat river Superficial water from Ter river Wells from Besòs river Underground water from Llobregat aquifer 2 WTP’s 1 WTP 1 WTP Desalinated sea water (2009) Water Supply in Barcelona
Treatment Plant processes • Pre-treatment • Clarification • Ozone-carbon treatment • Final disinfection • Membrane filtering (RED, IO)
Limited Supplies for the Barcelona Metropolitan Area Sources Total storage capacity: 612 hm3 Yearly demand: 615 hm3 Barcelona Metropolitan Area Supplies and Demands
Reservoir Capacities Ratio yearly demand/ storage capacity approx 1!
Ter Llobregat Besòs Desalination An Interconnected Network
A complex supply problem Problems of the Barcelona water system: • Semi-arid weather, limited availability • Limited infrastructure, no slackness • Poor water quality in one main supply • Low mineralization in desalinated water • Growing population and demand
The SOSTAQUA Project:Developments Towards Sustainabilty in the Urban Water Cycle (2007-10) • Industrial Partners: Agbar, Degremont, Dow Chemical Ibérica, Cementos Molins Industrial, Clabsa, Labaqua, Sener, Solvay, Emuasa, Cric, Canaragua, Auma, Remosa, Amphos 21, Stc, Sineria. • Public Research Institutions: UPC, CSIC, UB, UAB, UVa, UdGUAH, GIRO, CTM, URV, UG, UDC, ULPGC, IQS • 10 research lines in: • Water • Energy • Waste http://www.sostaqua.com
SOSTAQUA, Line 4: Optimal management of water supply • Goals: • To design a decision support software tool for real-time water supply management • Techniques: • Real-time control and supervision • Optimization • Simulation
Water Supply Management Goals • Demand-supply balance • Reservoir management • Ecologic flow guarantee in rivers • Flood prevention • Hydroelectric power generation • Acquisition, transport, treatment costs • Combined water quality to users
Conclusions Water supply in Barcelona involves challenges: • Social • Quality-of-service • Economic • Energetic • Environmental
