Drinking Water in Barcelona Gabriela Cembrano IRI, CETAQUA

Researcher at Institut de Robòtica i Informàtica Industrial (UPC-CSIC) Project Manager at CETAQUA Gabriela Cembrano

The Urban Water Cycle Before use: Intake Treatment Transport and Storage Distribution After Use: Consumption Urban drainage Treatment/regeneration Recycling Release to environment

4 sources of supply Desalinated sea water (2009) Underground water from Llobregat aquifer Superficial water from Llobregat river Superficial water from Ter river Wells from Besòs river 2 WTPs 1 WTP Water Supply in Barcelona

The WTP at Sant Joan Despí

Treatment Plant processes Pre-treatment Clarification Ozone-carbon treatment Final disinfection Membrane filtering (RED, IO)

Supplies and Demands Limited Supplies for the Barcelona Metropolitan Area Sources Total storage capacity: 612 hm3 Yearly demand: 615 hm3 Barcelona Metropolitan Area

Reservoir Capacities Ratio yearly demand/ storage capacity approx 1!

Desalination Llobregat Ter Besòs 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 Ter-Llobregat Basin

The SOSTAQUA Project: Developments Towards Sustainabilty in the Urban Water Cycle ( ) 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

Work lines in SOSTAQUA

SOSTAQUA, Line 4: Optimal management of water supply 1. Goals: To design a decision support software tool for real-time water supply management 2. 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

An example of DSS

Conclusions Water supply in Barcelona involves challenges: Social Quality-of-service Economic Energetic Environmental
