As an example, GIS applications can help identify trends in water main breaks
to prioritize pipe replacement and rehabilitation projects [10]. The database is structured using the desired criteria such as pipe material, diameter, age, surrounding
soil conditions, proximity, fault/break history, water quality, coordination with other
public works projects, etc. These criteria can be represented spatially in a GIS and
associated with the pipe inventory.
The coupling of a GIS system with hydraulic modeling software will allow managers to diagnose the water network, to study solutions to various problems and
to predict future behavior of the water system. Additional benefits can be achieved
by maintaining connectivity between the model and GIS [10]: fire flow analysis,
drinking water source analysis, water usage demand allocation, establishing facility
elevations, etc.
In Cluj-Napoca, the local water company RAJAC started in 1994 the first steps
in implementing a GIS application for managing its water and sewerage networks.
It is evident that GIS technology brings several advantages (saves time and money,
offers a decision-aid tool, has the potential for integration with other utilities and
gives active communication abilities), but prices were still very high at that moment.
Therefore, RAJAC chooses to implement an ad hoc GIS application, in collaboration with a local GIS developer, SC EGH SRL Cluj-Napoca. It was a cost-effective
solution, following many abroad examples: instead of a full-size professional GIS, a
simplified ad hoc mapping tool can offer almost the same functionality, with lower
hardware requirements [12]. Another reason for such an approach was that owning
a GIS will increase the value of the company, thus facilitating the access at tenders
for governmental or EU financed projects.
The name of this ad hoc GIS software platform was CADMOS-AC (Fig. 6.8),
and it provided:
– a graphical database structured on layers (including topographical maps and water
network maps overlaid);
– a tabular database structured as a set of alphanumerical attributes, where data were
obtained from archives or directly from terrain measurements;
– GIS specialized analysis: query reports, thematic maps and charts that further
support the decisional process and control of the network.
As input data, CADMOS-AC used:
– topographic maps scale 1:500 coming from Cluj-Napoca municipality (digital
format);
– water network maps (analog format), tabular descriptive data (analog format).
