4. Quinta do Lago
4
• A well known touristic resort
located in south of Portugal
• InfraQuinta is the water
utility that manages the
water services
• The main water distribution
network was built in 1972
• Since then, no rehabilitation
plan has been developed

5. The uncertainty of water demand in
Quinta do Lago
5
• High peak water consumptions: summer = 5x winter
• Atypical pattern: high peak at night (from 3am to 7am);
low peak during the afternoon (from 12pm to 7pm)
• High consumptions in outdoor uses (e.g. garden
watering) in comparison with domestic indoor water uses

7. Available data for hydraulic modelling
• Customer Relationship Management Systems (CRMS)
– Customer billing records
• Geographic Information System (GIS)
– Water supply geometric network and assets characteristics
• System Control and Data Acquisition (SCADA)
– Water levels, flow and pressure-head
• Telemetry system
– Network fully covered with volumetric flowmeters with fixed radio
frequency

9. Hydraulic and performance
simulations
• District Metering Area (DMA)
with 25% of the total consumers
• Real water demand (telemetry
data)
• Estimated water demand (given
by historic customer billing
records)

13. Conclusions
• Telemetry data hourly collected is of the utmost importance for the Planning
and Asset Management Department, that aims to:
– Establish a strategy for rehabilitation
– Improve water network in terms of hydraulic performance and energy efficiency
– Help the daily management (leakage assessment and burst/illegal uses detection)
• Hydraulic model with estimated water demand is enough for planning
purposes
• Real water demands is more adequate when a more detailed analysis is
necessary
