Water Industry Challenges


Towards Smart Water Networks

Move from DATA to INFORMATION AQUASAFE


Databases; Scada systems Third party forecast models

Local sensors

Sinchronize data; Modelling chains; Run operational models; Early warnings; Reporting

Publish (web, desktop); Run scenarios; System administration

AQUASAFE: What is it?

• AQUASAFE is a business intelligence platform supported by modelling tools and advanced data analysis systems


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.


Contribution of AQUASAFE to HIDROMOD’s business

Innovation: it is pushing the development of innovative

solutions (moving models from scenarios to real time)

Internationalization: It is driving HIDROMOD’s international

market (Europe, Asia, South America)

Partnerships: It is enabling the integration of HIDROMOD’s

technologies with other partners technologies (ex. Bentley,

Simtejo, IST, INTECMAR, Hydrologic, Univ. Azores, etc.)

Water Loss Reduction

Practical cases


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

AQUASAFE Integration in Operation


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


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


Keep a continuous tracking of the pumps functioning point


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

• Immediate saving is 100,000 £ (29% of original energy cost) • CO2 footprint reduction of about 132 tons • By optimizing pumping hours and better supply from storage sources


Wastewater systems operation improvement: SIMTEJO example

Practical cases


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)


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
