Non Revenue Water is the difference between total produced water vs the amount of metered and authorized un-metered use. • Apparent losses are metering, management and human errors that result in consumption without income. • Real losses is the amount of water lost due to waste in the network. These come from issues such as leaks, unreported bursts or other types of losses. Non Revenue Water can be calculated by ensuring that all of the data is available. • Various models are supported including SCADA and AMR integration

Traditional Approach to the Problems Planner interacts with hydraulic model using a trial and error process Options must be eliminated to create a single solution “What happens if we build…” Cost of solution is considered only after the model is created Only a limited number of alternatives can be evaluated and vetted 19

An Optimized Approach Planner includes: • • (1) Optimizer on your desktop • Objectives – (cost, pressure, water age, overflows, etc. ) – (pipe sizes, pump options, tank locations, etc. ) Decision Variables Constraints (2) Model run hundreds of thousands of times in “The Cloud” (3) Best solution that meets your triple bottomline objectives (4) “How can this plan be made more cost effective? ” Automate trial and error approach – Evaluate many more alternatives 20

Self Cleaning Networks or Flushing Application Self Cleaning networks are networks that are that do not need to be cleaned since they are hydraulically modeled to support a self cleaning function. Flushing Application is an excellent, water-efficient method of cleaning water distribution pipes to improve water quality and restore capacity. • Manage this based on Asset information • Plan Flushing activities

Resilience • How do we achieve Resilience? IMPROVEMENT OF KNOWLEDGE REQUIRED FOR UNDERSTANDING RESILIENCE A minimum level of data must be collected to complete the assessment. −− Data Registration, Quantity, Quality, Integrity, Management and Integration. Where data is not available it increases overall risk score, encouraging companies to collect the required data −− Distinguishes between lack of resilience knowledge and poor resilience, enabling businesses to focus attention appropriately −− Sets standards for the minimum level of data that all companies should collect IDENTIFICATION OF THE AREAS WHERE ABILITY TO BENCHMARK AND CUSTOMERS ARE MOST EXPOSED TO IMPROVE RESILIENCE ACROSS THE HAZARDS INDUSTRY ABILITY FOR CUSTOMERS TO ACCESS TRANSPARENT INFORMATION ACROSS THE COUNTRY By assessing resilience at a system level, the metric can be used to: The metric produces a normalized company resilience score and a resilience score by system and hazard. Resilience is assessed by system and demand management zone, allowing customers to: This enables companies to: −− Understand which hazards present the greatest challenges in the area they live −− Identify systems exposing assets and customers to service interruption risks −− Understand the interventions required to improve the resilience scores −− Prioritise investments −− Benchmark their level of resilience against other companies, driving more proactive improvements −− Understand which hazards present the greatest challenges/risks in their specific circumstances, collaboratively driving innovations −− See their resilience score change over time, demonstrating improvements −− See how they rank compared to other areas and what organizations are doing to improve their rankings
