To: Board of Directors
From: Joe Horvath
Date: May 04, 2011
Subject: Consideration of the Award of a Contract for the S 'SCADA Conduit
and Vault Project and a Report on the Optical Data Network
Reliability Improvement Project
I. WHY THIS MATTER IS BEFORE THE BOARD
Board approval is required for expenditures in excess of$15 000.
2. HISTORY
The District has 5 electric and 55 water facilities located throughout
territory. These facilities include electric our service
substations, pump stations, wells, storage
tanks and control valves. We communicate to these facilities over s
media including leased data circuits dial-u t everal types of
p elephone lines, cellular modems and a
variety of radio systems. These systems, which serve Electric and
I antiquated Water SCADA
systems, are becoming increasingly y t quated and are experiencing ongoing loss of
reliability issues with the equipment itself and also with our t
personnel elecomm carriers.
Frequently, we dispatch
p el out to remote facilities to troubleshoot
communication problems, adding to operating costs. We are also severely limited in
due to bandwidth restrictions the type and amount of data we can transmit inherent to
older technology. In addition, only basic security protocols are avail
