RECOMMENDED ACTION
Direct the City Attorney to prepare and authorize the City Manager and the
Clerk of the Council to execute an agreement with Transdyn, Inc. to
provide hardware and software upgrades to the Supervisory Control and Data
Acquisition System for the City's water production facilities for a fixed
fee of $950,000.
DISCUSSION
The City's water production facilities are controlled by a Supervisory
Control and Data Acquisition (SCADA) System. The system utilizes remote
programmable controllers at each water production site and a central
computer system located at the City Yard to remotely operate wells, pumps,
and reservoirs. Uninterrupted reliability and functionality of this
system is required to maintain operation of the water system. The
existing system was installed by Transdyn Controls, Inc. in 1992 and was
upgraded in 2000.
Due to the age and obsolescence of the existing hardware and software, the
programmable logic controllers located at each of the City's 38 water
production facilities must be replaced. New central computers located at
the City Yard are also required to provide fail-safe protection and
uninterrupted operation of the water system.
The proposed upgrade project also includes the installation of a radio
based communications system. This system will replace the current leased
telephone line system, providing increased reliability and will result in
an annual cost savings of approximately $40,000 in phone charges.
The current system provided by Transdyn has functioned since 1992 without
failure. Staff recommends that Transdyn Controls, Inc. be retained to
provide the required upgrades for a continued uninterruptible and
functional system.
