Supervisory Control and Data Acquisition (SCADA) Telemetry System
Project Description
In the early 1990's the City of San Diego Water Department embarked upon
a long term strategic view of its water infrastructure control system.
The purpose of this evaluation was to find where improvements could be
made in water distribution and maintenance through the use of technology.
The evaluation focused on improving the speed and effectiveness of in-the-field
repairs to the system, increasing the speed of discovering and responding
to system failures, and integrating the data collection and monitoring
into a single system-wide control center.
Years of dedication and planning paid off when, in 1998, the City Council
authorized the Water Department to replace the existing operating system
with the radio-based Supervisory Control and Data Acquisition (SCADA)
telemetry system. In August 1999, the Water Department completed the installation
of this state-of-the-art telemetry controls system. SCADA is a computerized
control and monitoring system which will serve as the main operating window
for the City of San Diego's entire water distribution system.
Construction Start: Spring 1998
Construction Complete: Summer 2001
Project Benefits
- Increased reliability and efficiency
- Reduced costs
- Flexibility for system growth
- Improved operator interface and communication
- Increased data accuracy
- Effective data management
- Fully integrated information systems
- Ultimately monitor and/or control operations at 400+ sites remotely
- Redundant servers, workstations and laptops for increased reliability
- Relational database server to provide the SCADA data to the Water
Department Enterprise System for improved system maintenance and improved
water modeling
Project Need
Across the country, utility departments are incorporating technological
innovations to increase performance. With newer technology such as SCADA,
the Water Department is able to improve the speed and effectiveness of
in-the-field repairs to the system. This means shorter traffic delays,
more warning and faster containment by increasing the speed of discovering
and responding to system failures. Also, this new data management system
integrates the data collection and monitoring into a single system-wide
control center for more streamlined data utilization.
Estimated Project Cost: $4 million
