In the late 1990s, Dallas Water Utilities (DWU) required substantial improvements to its
440-mgd East Side Water Treatment Plant (WTP), a facility which had not been
upgraded since the early eighties. In addition to improvements to the raw water supply,
finished water pumping, and conventional treatment systems and construction of a new
ozone facility for primary disinfection, DWU required a state-of-the-art computer-based
supervisory control and data acquisition (SCADA) system that could successfully
accommodate the extensive upgrades.
The project required a phased approach that allowed
DWU to acquire the necessary funding to complete improvements, accommodate
construction, and keep the plant operational. Because the work was phased over a 5-year
period, DWU - concerned with retaining continuity over multiple construction projects
with different contractors and suppliers - chose to partner with the SCADA system
design team for software programming and application engineering services.
This paper demonstrates how the partnering approach, combined with the use of
standards and conventions, provided a consistent product over the multiple construction
phases and reduced programming errors, increased reliability, minimized training
requirements, and provided user friendly systems, while providing unique benefits to all
stakeholders. Includes figure.
