1 Crowder Consulting - Netbase Dynamic and Real Time Modelling Consultants Perspective George Crowder

2 Introduction Crowder Consulting - Netbase

3 Crowder Consulting - Netbase Introduction Dynamic Modelling Maintaining accurate and up-to-date network models which can be used to predict potential problems in the network and investigate solutions. The processes will involve automated data updates, efficient data validation and dynamic links to time series data.

4 Crowder Consulting - Netbase Introduction Real Time Modelling The ability to use dynamically maintained models with real time data for both past and current analysis. This will enable network status to be predicted during a specified period for the purpose of calibration, leak detection analysis, serious incident resolution etc. Real time modelling involves deriving actual demand or forecasting future demand and capturing the status of pumps, tank levels, controls, boundary flows and pressures for the time of analysis (past or current).

7 Crowder Consulting - Netbase The Importance of Demand Analysis

8 Crowder Consulting - Netbase The Importance of Demand Analysis Demand Types Attributing all demand types to nodes Households Non-Households Continuously Logged Leakage

9 Crowder Consulting - Netbase The Importance of Demand Analysis Base Demands Analysed from: Billing data & GIS property seeds. Nightflows Diurnal Pressure Profiles Water Balance Components for unmeasured households

10 Crowder Consulting - Netbase The Importance of Demand Analysis Net DMA Profile HH Profile Leakage Profile NHH Profiles Demand Profiles Built and derived dynamically e.g. Leakage Profiles from pressures and night flows Household profiles by deduction from net DMA profiles

11 Crowder Consulting - Netbase The Importance of Demand Analysis Large Cont Logged Profiles Smaller NHH Profiles Non-Household Demand Profiles Should include continuously logged customers and other individually monitored profiles separately. Other non-household profiles based on standard types derived from monitored data
