IAWD Asset Management Regional Services Hub –

Asset Management Activities

Presented by:

Dr. P. Kolovopoulos

UTVSI

Agenda

AM Hub Centre Operation

AM Hub – AM Activities

Dissemination of a methodology to allow the generation of Management Reports for a utility based upon technical and commercial inputs.

Management guidance, to interpret management reports and formulate appropriate decisions

Assistance in creating effective management reporting at all levels

Utility performance assessment, through the involvement of industry experts to help analyse the Utility’s performance and to identify appropriate remedial and proactive activities

Support for regular System audits, identifying problem areas both with regard to usage of the system and business procedures

IAWD Asset Management Regional Services Hub

Asset Management Activities

The IAWD AM hub will use the latest available AM technology capitalizing on the development efforts and knowledge built in Belgrade Water Works over the last 10 years.

BWS has already a pool of available resources trained in AM techniques and systems that can provide the services and use the existing infrastructure (EDAMS)

The AM will operate primarily through cloud technology with reduced operational costs, enabling much easier participation of Utilities.

IAWD and BWS will evaluate in the course of the project the development of a business model to maintain and support the activities on a cost recovery basis after the completion of the project.

Utilities participating in the program


Parties Involved

Direct access to customers and uploading / downloading of information

through EDAMS-CRM application

EDAMS CRM is a simple, easy to use portal for the exchange of

information between the customers and the center.


Implementation of Services

All geographical data is published on EDAMS-Web-GIS and Client is given

one free license of the software to use

EDAMS Web GIS is a simple, easy to use web GIS application. Your

selected network can be viewed, queried and analysed, e.g. producing

thematic reporting of water quality at monitoring points.


Implementation of Services

Utility Assessment & Recommendations

Regular Management Reporting

On-line access to GIS data & reports

Direct support though CRM and assistance

Workshops & training per phase

Dissemination of information through Seminars, papers etc.


Project Outputs

Frequency of reporting is recommended and can change to suit

requirements

Reports are consolidated to 3-monthly, 6-monthly basis

Access is given to EDAMS-CRM web site for submitting and receiving

reports

Reports are accompanied with excel files and shapefiles for element

reference

Progress reports indicating key indicators of all previous analyses are given

Objectives

Efficient monitoring of bulk meter operation and monthly evaluation of bulk meter readings.

UFW analysis of Mass Balancing Zones (MBZs) using IWA (International Water Association)

“No-Drop” Legal requirement reporting

Data Requirements/ prerequisites

Commercial Data Evaluation (CDE)

[calculates authorised metered demand and metering inaccuracies –geographically distributed]

Asset register Evaluation (ARE) [defines MBZ]

Bulk Meter Readings [used to calculate supply per zone]

Un-Accounted for

Water Analysis

(UFW)

Unaccounted for Water Analysis (UFW) - Methodology &

Procedures


Activities

Bulk Meter Readings Evaluation

[imported, time series – corrections, flow generations – fill in gaps]

Supply Analysis (per MBZ)

[bulk meter equation/ MBZ – problems with meter locations & readings]

Allocation of demands to pipes and to MBZ

[CDE Demands are allocated to plot => pipes => nodes => zones]

UFW analysis per zone

Supply = metered demand + metering inaccuracies (apparent losses) + unauthorised consumption (assumed) + leakage

Leakage performance is evaluated against IWA standards
