HomeMy WebLinkAbout5.E.2. Approve Quote for Fiber Installation to Lift Station No. 16 ,5,
CITY OF SHAKOPEE C n' 17t
Memorandum 6 1
TO: Mayor & City Council
Mark McNeill, City Administrator
FROM: Bruce Loney, Public Works Director
SUBJECT: Approve Quote for Fiber Installation to Lift Station #16
DATE: June 5, 2012
INTRODUCTION:
Attached is a quote from Arvig Communications Systems (ACS) showing the installation of
fiber communication lines in the City system to Lift Station R16. The action for City Council is
to approve this quote by a Fiber Communication Contractor to do work for the City of Shakopee.
BACKGROUND:
As part of the July 21, 2001 Lift Station 16 Emergency Operating Plan, one of the
recommendations for the City to consider was a more reliable supervisory control and data
acquisition system (SCADA) which can provide better communication and emergency response
to the lift station.
A communication systems contractor is going to be installing a fiber system and will be going by
lift station 16 while doing their installation for another party. Staff has been working with this
contractor, and they can provide another conduit with fiber at a very reasonable cost. The quote
for this fiber in conduit is $17,563.
In addition to the City interested in fiber for our L16 Lift Station, Shakopee Public Utilities is
interested in sharing this conduit fiber for their future electrical and water utility
communications. Staff is working with Shakopee Public Utilities staff and the exact cost share
for participation is not known at this time until it is discussed with the Commission. Installation
of this conduit and fiber is being considered at this time for the City in order to meet the
contractor's schedule for late June.
Also attached is an email from a City's consultant in regards to communication systems and
what is the best alternative. The consultant is recommending that City owned fiber is by far the
most reliable and the best system to utilize for its communication. Other costs will be needed to
connect into the existing system and lift station. Also there will be additional hardware and
software costs to utilize the fiber for communications. By going with fiber installation and a new
communication system, the SCADA system will be more reliable and have more capabilities.
Also the sewer plan shows 9 lift stations total and this initial system can support each future lift
station when connected to fiber.
ALTERNATIVES:
1. Approve a motion approving the quote submitted by Arvig Communications System of
Perham Minnesota and this would be paid out of the sanitary sewer enterprise fund.
2. Do not approve the quote from Arvig Communications System for this work.
3. Table for additional information.
RECOMMENDATION:
Staff would recommend alternative no. 1 to bring fiber to the L16 site for future SCADA system
improvements.
ACTION REQUESTED:
1. Approve a motion approving the quote submitted by Arvig Communications System of
Perham Minnesota and paid out of the sanitary sewer fund to bring fiber to the L16 site
for future SCADA system improvements.

Subject: RE: Lift Station L 16 SCADA System for Fiber Optic Network
Bruce. Per our discussion there is a variety of methods of communicating to Public Works including telephone, radio
(multiple radio methods), internet based systems and fiber. Radio faces availability of licensed frequencies issues and
congestion on the spread spectrum channels in addition to weather interference. Telephone lines, which once were the
predominant method can be expensive and reliability issues can occur. Cell phones can have the same issues along with
potential security issues for some of the current technology. Internet based systems can have problems related to
reliability if the Internet connection fails, if the system depends on satellite communication or the Internet server goes
down. With 'cloud' computing security issues can abound and with Internet based systems you are generally dependent
on a single vendor. As long as the representative is good that type of system can work well. If the representative is not
responsive or technically savy the system can be unreliable. Fiber optic is owned by the City and you have a variety of
local system integrators that can support the system. If the fiber optic cables are deep, dig ups are reduced and system
reliability can be better. Fiber optic systems can have the same disadvantages related to power outages, etc but
generally the system is more in the 'hands' of the City and is more reliable. This assumes the cables are in conduit and
are deep. The initial investment is high but if the City is looking to expand to other stations and facilities this type of
system is favored by several cities and would be the backbone and could include PBX telephone, a variety of alarming
systems and monitoring for security, etc. One thing we did talk about that is not in the estimate is the capability for
remote access to the system Access would be via laptop but again, we need to discuss system security before that
would proceed. The costs are 'order of magnitude' and if the City chooses to take the next step we would recommend
an effort to refine and document the system configuration and then the estimate. Let me know if you have questions.

Tom we would have to have a cost to bring fiber into the L -16 and to connect to the existing fiber on 4th avenue. I will
try to get these costs from Jim. Paul do you still feel this is a good investment for the city to do?

Bruce:
Attached is an e-mail from Paul Kaeding that outlines the hardware, software and their cost.
I also called Paul regarding installation cost. At Public Works, you will need to extend fiber optic cable over to the work
station, as well as, a phone line unless one already exists. Without knowing location, it is difficult to prepare an exact
estimate. However, maybe a cost estimate of $2,000 is appropriate for the work inside of Public Works. At the lift
station, the PLC and the modem will have to be installed and a connection made to the fiber optic cable. Also, all of the
Modicon points will have to be connected to the PLC that Paul refers to below. Because all of these points are currently
connected to the two Modicon boxes, it would be logical to install the PLC in the location of the boxes and simply make
connections to it. Again, maybe $2,000 is appropriate for this work.
With the $4,000 installation cost added to the $40,000 to 50,000 estimated below, the cost estimate is $44,000 to
$54,000. The remaining thing to do is to check with Jim Henderson on the cost of getting the fiber optic to the outside
walls of both the Public Works and L16 buildings. I am not certain whether the cost estimate he got takes the fiber optic
into the lift station site. From the INET map, it appears as if fiber optic will have to be extended from the Police Station
to Public Works.
Jot me a line back or call with questions.
FYI!

The system considered would include a small PLC with a fiber modem at LS16 to pick up the points from the existing
Modicon PLC. The data would be transmitted via the fiber optic cable (fiber not part of this estimate) to Public Works.
At Public Works there would be another small PLC to convert the fiber back to signal. The Public Works would also
include a 'hard wired' backup dialer and a workstation that would be running Wonderware of RSView with a software
based alarm dialer. Cost estimated at $40K to $50K not including installation.
