 The preservation of quality and quantity of groundwater, today under
stress, imposes the integration of new automated methods and tools for
the continuous monitoring of all its parameters. GEOSERVICE provides
today a full list of services in the design, installation and management
of modern environmental monitoring systems, such as:
- Supervisory Control And Data Aquisition (SCADA) installations
for water systems and aquifer management
- Development of specific application software with early warning
and prediction capabilities
- Installation of remote telemetry equipment

The Aquifer Monitoring System of Water Supplier of
Athens (EYDAP SA)
|
|
|
 Introduction
Athens, the capital of Greece, depends heavily on water for its
activities and the preservation of the living standards. EYDAP SA, the
Water Company of Athens decides to build a computer controlled Aquifer Monitoring
System (AMS) for the sustainable management and protection of its
groundwater resources.
|
System characteristics
 The system,
realized from GEOSERVICE, has the following capabilities:
- Real time display of groundwater parameters
(groundwater head, water conductivity, pH and related electrochemical
factors) together with pumping rates
- On line protection for sea water intrusion
- Continuous data acquisition
- Early warning capabilities
- Groundwater level prediction algorithm
- Remote operation through SMS messaging
|
System description
 The AMS system, designed and installed for EYDAP SA completely from
GEOSERVICE, is based on:
- One new electronic module driving all analog measuring components
(pressure, temperature, conductivity sensors etc)
- One set of ADAM 4000 remote data acquisition modules from
ADVANTECH arranged in one RS-485 network on one total length of 1800
m.
- One software platform, integrating on-line specific algorithms for
hydraulic modeling with groundwater level prediction capabilities.
- One complete weather station
|
Conclusions
The continuous use of the LAAMS system
during the last four years, has significant benefits for the Water
Supplier of Athens such as:
- The total pumping rate of the water
stations has been increased as a result of the accurate calculation of
the resources from the model algorithm
- The danger of saline water intrusion has
been diminished.
- The water quantities have been digitally
recorded with accuracy for the first time.
- One strong water quality database has
been created.
