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 WTP’s 1 WTP 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

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
