WORKSHOP
To: Board of Directors
From: Ed Taylor
Date: February 04, 2009
Subject: Discuss the Status of Water SCADA Replacement Project
1. WHY THIS MATTER IS BEFORE THE BOARD
This Workshop item is informational to provide the Board with an update on the Water
System Supervisory Control And Data Acquisition system (SCADA).
2. HISTORY
The Water Department is using 3 completely different SCADA systems to control the
delivery of water to our customers. These systems are for the Main Area, the
Glenshire Area, and the Donner Lake Area. The physical water system works as one
integrated system, but the 3 different SCADA systems do not. This leads to control
problems and a loss of overall operating efficiency.
The Main Area and Glenshire Area SCADA systems were put into place in the early
90's. The Donner Lake SCADA system was built in the late 90's. Since the Main Area
system SCADA was put into place, we have also added 15 new facilities that require
some kind of SCADA control (4 wells, 2 tanks, 6 booster stations, and 4 control
valves). To make these facilities work with the SCADA system, we have used up all
the remaining expansion capacity in the system that were purchased for expansion.
3. NEW INFORMATION
The three current systems do not meet any of the current industry standards. New
SCADA systems are to control the delivery of water and do so in the most energy
efficient operation. The District's Water system has 76 remote sites which are
monitored and/or controlled by the SCADA system. The system also monitors 1,600
information items in the water system. The monitored locations include tanks, pumps,
wells and control valves. The monitored items include levels, on/off conditions,
operational conditions, energy use, efficiency, and security. The current SCADA
systems can not provide all of the functionality that is needed.
The 2006 COP included $400,000 of funding specifically for the replacement of the
Water System SCADA and up to an additional $800,000 of un-designated funding.
4. FISCAL IMPACT
There is no fiscal impact associated with this matter at this time.
