AQUASAFE: What is it?
• AQUASAFE is a business intelligence platform supported by modelling tools and advanced data analysis systems
13th European Forum on Eco-innovation
What distinguishes it from other systems?
• First: Versatility
• Second: capability to adapt to different users
needs.
• Third: capability to link with several commercial
and open source models, databases or data
sources (use what you already have)
Why to use tools such as AQUASAFE?
Focus on prevention, instead of the
traditional reactive approach, making use
of advanced data mining and modelling;
Improvement of systems intelligence in order to automatically
detect anomalies and provide support to early warning.
Provide tools capable to integrate real time data and models
and, by this way, make available an increased capability of data
analysis, malfunctions detection and anticipation and acting
accordingly.
13th European Forum on Eco-innovation
Contribution of AQUASAFE to HIDROMOD’s business

Water Loss Reduction
Practical cases
13th European Forum on Eco-innovation
Water Loss, How big is the Problem?
• 48.6 billion m3/year is lost around world (World Bank 2010)
• About 21 billion liters / day lost in EU (IWA, 2011):
• Benchmarks in EU water utilities show physical water losses between 15-60% and ILI > 5
• Existing leakage is alarmingly high, putting stress on water resources and aquatic ecosystems

13th European Forum on Eco-innovation
Current Practice
1. Assessment – water balance or water auditing based
upon water infrastructures’ physical data and some statistics
2. Pressure Management – Divide the network in Pressure Zones and
DMAs
– Use hydraulic model for PRVs
– Install PRVs to manage MNF
3. Active Leakage Detection – Sounding for leaks
– Step-testing
– Acoustic loggers (noise correlators)
– Smart balls
– Use hydraulic model and measured (Scada) data

Energy and CO2 reduction
Practical cases
13th European Forum on Eco-innovation
Pumping Scheduling = Energy Efficiency
• What to schedule – Which pump is on duty
– When pump is on duty
– What speed is on duty
• Goal – Minimize energy consumption (CO2 footprint)
– Minimize total energy cost
• Supply requirement – Hydraulics
– Manage pressure (water loss)
– Water quality
13th European Forum on Eco-innovation
Keep a continuous tracking of the pumps functioning point
13th European Forum on Eco-innovation
Case: water system in UK • DMZ system
• 57 Ml/day
• 11 pump stations and 9 tanks
• Energy cost: £330K/year
• Recorded daily energy cost: £912
• Modeled daily energy cost: £923 Optimization

Wastewater systems operation improvement: SIMTEJO example
Practical cases
13th European Forum on Eco-innovation
Innovation in SIMTEJO operation
Moving from Data to information and knowledge –
Network model moved from planning tool to a decision
making tool integrated in day-to-day operations
Operational forecasts of the system state, defining alerts,
producing automated reports.
Integrated management (meteo,
sewer, WWTP and river)
13th European Forum on Eco-innovation
Reporting: Prevent, detect, evidence and respond from normal
operation, to emergencies and customer complaints, by
modeling emergency and planning scenarios, and real-time
operations.
Environmental impact mitigation (estuary discharges).
Controlled overflows will reduce the negative environmental
impact on local estuary and potentially lead to improved
recreational use

Conclusions • Improving efficiency is a part of a Eco-innovation practice in EU
Water Utilities
• Real-time data streams, hydraulic modeling and optimization technology can help: – Reducing Water Loss and Detecting leakage hotspots
– Optimal energy and pressure management (including CO2 footprint)
– Prevent environmental disaster using smart platform such as AQUASAFE
• Takeaway message: From ‘dull pipes’ towards Smart Water Networks thru technology innovations
