SUBJECTS S C A D A System Master Up-Grade and Duplex
As you are aware, we have discussed the up-grade and duplexing of our
master for quite sometime We have allocated some $200,000 for this
project in our C I P for the Fiscal Year 1987 We have also discussed
functions we would like our system to perform ranging from computer
aided distribution to mapping I have ask for, and received, quotes
from the two leading companies in this field They are TEJAS out of
Houston, Texas, and ADVANCED CONTROL SYSTEMS out of Atlanta, GA
The quotes are as follows:
TEJAS quotes two systems one quote is for their "generic" system,
and they provide system support
TEJAS second quote is for a "DEC" system with support by "DEC"
The TEJAS quote includes four new CRT's and two new printers
The quoted prices are $210,000 for the system they support and built out
of "DEC" and third party vendor items The prices for a total "DEC"
system is $245,219 00 Both systems have a $31,422 00 adder for spare
parts
The only problems I see with TEJAS is the fact we would be operating
with two different protocols (B W T -BASIC and A C S and we would
eventually operate with three until B W T -BASIC, and R T U 's could be
replaced The quoted price for system one (1) is also higher than the
A C S quotes
1 The A C S quote has two options Number (1) is $179,275 00
This is based on HP-A600 CPU's
2 Number (2) is $251,595 00 This is based on HP-A900 CPU's
A C S has a spare part option quote of $3,386 00 if required
A C S will change out our B W T-Basic, R T U 's and turn them into
A C S -R T U 's for the price quoted for option 1 or 2 This is a real
advantage since we would only be using a single protocol, and the R T U
parts would then all interchange This is a real plus from our
operations stand point
Based on these facts and fiqures, I strongly recommend the A C S quote
be accepted for option (1) at $179,275 00

FROM: Ray D. Wells, Superintendent, Metering & Sub Stations
THROUGHS R E Nelson, Director of Utilities
SUBJECT: Support/Background Information - S C A D A System
The following background information is intended to inform the Board
members of our previous S C A D A system purchases, costs and problems
The electronics industry has, for many years, been a fast changing
industry I sometimes think that the electronics firms market planned
obsolescence However, I suppose like many other businesses and
services, new developments are faster coming and carry more profound
impact than others
A) First actual S C A D A systems purchased in 1974 with final
equipment delivery and on line operational use being 1979 The supplier
was B W T - Basic of Houston, Texas, and Black and Veatch was the
consultant firm for specifications The cost of the original system was
in excess of $400,000 00 with about $200,000 00 directly attributable to
the master station We had many problems primarily with the software
A fixed hard program was utilized not allowing access to the software
for changes or expansion This turned out to be very expensive and not
a system we could live with We learned a very important lesson
B) Second S C A D A system purchased in 1982 with delivery and on line
use some four (4) months later The supplier was Advanced Control
Systems, Atlanta, Georgia We did not use a consultant All
specifications were generated in house, and installation was with our
own personnel The cost of this system was $101,045 00 This has been
a very good system At the time it was purchased, it was top of the
line offering as many functions as were available We have lust
outgrown the system's capabilities and have developed a greater need for
total reliability thus the duplex requirement
The need for our upgrade and duplex of the master station, which is the
brain of the system, is based upon the following needs
1 Our systems dependence on outside power generation to meet our
system demands
2 Multiple interconnection points between our system and the power
pools
3 Requirement and ability to know instantly what is happening
throughout the system!
4 Need to expand into areas of load control and management
5 Need to update engineering data requirements
The system we now have will not do all of the above requirements

Subjs Emergency purchase of rear-end for sludge injection vehicle
Two days ago the rear axles on the Big A, sludge injection
vehicle, broke and rendered the vehicle helpless concerning land
injection of sludge. The reason the axles broke is due to a worn
out rear-end, in addition to the overall worn out condition of the
vehicle.
We can purchase a now rear-end for 25% less than the usual
cost. Our cost would be 8119555.00 Total cost including freight
would be 8129000.00. This would increase the vehicle value by
8159000.00. Delivery time would be one week. We have the money in
our vehicle and equipment account.
We are at a critical time concerning sludge disposal We are
cleaning beds in preparation for the rainy season and land injection
of the sludges is critical for us to be prepared for the wet season.
We, therefore, respectfully request that we be permitted to
purchase the rear-and assembly for the Big A immediately on an
emergency basis waving the public bid requirement.
Thank you for your support concerning this matter.
