Data Systems

# Muncipality Country

Data

Syste

ms





Group I (4 Municipalities): These Municipalities have gone through extensive network data

capture exercises and it is considered that they have collected most of their data. They have

active GIS/CAD systems/units.

Group II (6 Muncipalities): These Municipalities have collected more than 60-70% of their network

data and are using some form of CAD/GIS.

Group III (7 Muncipalities): These Municipalities have more than 25% to 30% of the networks

unknown, or they have networks only in hard copy plans and they have very little knowledge/use

of GIS/CAD systems.


Initial Period Activities

The results indicate that most of the Municipalities are involved in some form

of leakage detection activities; however, without proper mapping of the actual

network assets, the exercise has very limited effect.

Some of the questionnaire replies regarding the operations and management of

zoning indicate that the Utilities do not fully understand or appreciate the

importance of zoning and training will be needed to address this problem, i.e.

Many Utilities (9 out of 17) reported that do not know or manage their

pressure zones.

Most Utilities (11 out of 17) reported that they do not have DMA zoning.

Some of the Utilities that reported that their DMA zones are being

monitored, either they do not have telemetry or they do not have bulk

meters.



The initial assessment

indicates high levels of

NRW for all the

Municipalities in the

range of 40% to 60% and

high levels of leakage

and unbilled

consumption.

These results confirm

that the Utility problems

are not only technical

but also commercial and

that parallel actions will

have to be implemented

in term of commercial

rehabilitation programs.

Activities

Initial Period Activities & adjusted implementation


Objective assessment of Utility’s performance

Quantifies lost revenues and excessive production and

distribution costs attributable to the different components

of non-revenue water

Recommends achievable performance objectives

Identifies and prioritises the different remedies that will

result in the performance objectives being achieved

Provides guidelines for systems and projects necessary

to achieve the recommended performance objectives

Project Challenges & Sustainability

The IAWD AM hub uses 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

The AM needs to operate through cloud technology, enabling much easier participation of Utilities.

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