FISCAL IMPACT:
SCADA.DOC
':
Based on the Council action at the October 6, 1997 meeting
plans and specifications for the water SCADA system have
been prepared. Plans are available through the City's
consultant engineer (Bonestroo). Councilmembers
interested in reviewing these plans should contact the City
Engineer to arrange a review.
The new SCADA system will monitor the operation of, and
connect all of the City's key water distribution facilities via
radio to a main computer control center at the maintenance
center. These facilities include 3 well houses, two water
towers, and the Wilds booster station. The current system is
dependent upon the phone system which is subject to
interuption. The current main control center is located within
wellhouse #3 which requires personnel to go to this location
to check and monitor the water system. The current controls
have been corroded by the chemical environment in the
wellhouse and have been rendered unreliable.
ISSUES
Equipment lead time requires this contract be let now and
awarded as soon as possible in order to be installed upon
the completion of wellhouse #3.
A sanitary sewer SCADA system is currently programmed in
the 1999 C.I.P. (Capital Improvement Program). Both
SCADA systems will be monitored and controlled from the
same main computer at the maintenance center. The main
computer will be acquired now with the water system
SCADA system.
CONCLUSION
The current SCADA system is unreliable and requires
replacement in conjunction with the reconstruction of
well house #3. Replacement of the water distribution system
SCADA system was approved at the October 6, 1997
Council meeting. Plans and specifications have been
prepared and authorization for advertising for bids is
recommended.
The current estimate for the SCADA system is $162,000 and
is proposed to be funded through the Trunk Reserve Fund.
