This document summarizes a presentation about smart water networks. It discusses how smart water networks use information technology to optimize water utility management with minimum capital expenditures. Examples are provided of smart water network implementations in Belo Horizonte, Brazil and Qatar that have helped reduce non-revenue water and improve maintenance practices. The conclusions emphasize that smart water networks can improve both operational and business benefits by maximizing existing IT systems and integrating data from different platforms through a centralized GIS system.

Improved decision making Increase customer satisfaction
- 4. Smart Information for a Sustainable World Do we need to increase efficiency? The total energy consumption of US water utilities is estimated to be 56 billion kWh equating to $4 billion annually in OPEX (EPA) Between 5-10 billion Kw/h of power generated in the US is spent in water that is either leaked or not paid for by customers (AwwA) In developing countries, about 45 million cubic meters are lost daily through water leakage in the distribution networks — enough to serve nearly 200 million people (WB). Energy prices increase at a faster rate than water tariffs meaning reduced margins for water utilities.
- 5. Smart Information for a Sustainable World Framework: Improving efficiency ↑ CAPEX for improving efficiency: i.e. pipe replacement, installation of VSP,… Fine, but: • High amounts • Approval periods • Budgetary • Implementation constraints periods Current IT capacity is not used at a 100% • Projects are not • Not getting the best aligned out of the • Data silos investments

- 12. Smart Information for a Sustainable World Example 1 – Belo Horizonte - Brazil - Utility Name: Copasa - 12.1 million people served (5.6 Belo Horizonte) - Improved response on - Over 40000 km of distribution pipes outage events - (↓14% outage times) 14% SCADA Maintenance - Improved maintenance policies Operational data - (↓33% repair times) 33% - Improved network control Data Maintenance Real time data Simulated data Predicted data - Improved planning GIS Hydraulic Model - Improved public image Geodata - Increased ROI on all these investments
- 13. Smart Information for a Sustainable World Example 2 – Qatar’s Water & Electricity Corporation - Utility Name : Kahramaa - NRW is the result of a - 1,4 million people served water balance that takes - Over 2500 km of water supply pipes into consideration data - Produces 360 Mm3/year coming from CRM/Billing, Metering, GIS, SCADA, Leak Billed Water Exported Detection systems Billed Authorized Billed Metered Revenue Consumption Consumption Water Authorized Billed Unmetered Consumption - Telvent has helped KM to Consumption Unbilled Metered Consumption reduce KM’s NRW to more Unbilled Authorized Consumption Unbilled Unmetered than half in 4 years, Consumption resulting in water savings Unauthorized Consumption System Input Volume Apparent Losses Customer Meter up to 57 M€ (14M€/year) Inaccuracies Non Leakage on Transmission Revenue and Distribution Lines Water - KM as most efficient water Water Losses Leakage and Overflows at utility in GCC area Storage Tanks Real Losses Leakage on Service - Only 3pp behing USA Connections up to point of Customer Meter average

Planned service interruptions: The public water supplier shall give reasonable notice to the affected customers prior to a planned service interruption affecting quantity or quality of the water delivered to the customer. If the interruption is scheduled to exceed 8 hours and affect 15 or more service connections the water supplier shall also notify the Department. 52 Pa. Code 67.1 (b) All electric, gas, water, and telephone utilities shall notify the Commission when 2,500 or 5.0%, whichever is less, of their total customers have an unscheduled service interruption in a single incident for six or more projected consecutive hours. CIS GIS Hydraulic Model 1.- Customer notification 2.- Identification of unnplanned & collateral effects in advance
