The Amador Water Agency recently held a special
meeting regarding the further implementation of upgrades to a system that
monitors and controls many of its plant operations.
The System is called SCADA, which means Supervisory, Control and Data
Acquisition. Water Agency General Manager Jim Abercrombie explained to the
Board of Directors, and public in attendance, that SCADA is used to monitor
water quality, tank levels, water flows to fill tanks, pumps stations and to
control the treatment plants as well. Abercrombie also
explained that the system will allow for the upgrade and expansion the agency’s
capabilities to serve its customers water needs. The goal for the Water agency with the SCADA system is
to coordinate the operation of all agency facilities in order to enable the
Amador Water Agency to treat and distribute water efficiently to all customers.
Abercrombie stated that “The
SCADA system (has been proven to) improve reliability for customers, as well as
improving regulatory data gathering necessary
for mandated reported to the Department of Health Services.”
Another benefit of the system is that it allows agency staff to control and
monitor operations from porthole locations. For example employees can use a
laptop computer to dial in from home on a prescheduled basis to ensure the
facilities and operations are appropriate. This benefit from the system’s technology upgrades
increases employee productivity and saves man hours according to
Abercrombie. This system is especially important to water users in the
Upcountry areas that are part of the Central Amador Water Project. Many of this
system’s components are separated by distance. This requires a staff member to
drive from tank to tank to check for operational efficiency or to troubleshoot
and look for problems with the system. Typically, agency staff has been forced
to rely on customer identification of problems in this system. The SCADA system
would put all of the tanks, and therefore the issues and problems that could
occur, within the realm of a single computer screen. The system was originally
approved and in 1993 and installed in 1995. Since that time multiple upgrades
have been made, however this new move toward a greater technology will be by
far the most expensive and advanced upgrades to date. Overall, the systems would be applied to the
Agency Network & Wide Area Network (WAN) including the Buckhorn Water
Treatment Plant and Central Amador Water Project Tank Sites & Pump
Stations, the Tanner Water Treatment Plant and Ridge & Trentway Pump
Stations, the Ione Water Treatment Plant and Prison Tank and all Camanche
Wells, Tanks and the area’s Lift Stations. At
the meeting the water agency Board of Directors expressed their pleasure with
the progress that staff has made toward implementing this technology. Also, a
list of other facilities and future facilities that the agency would like to
add to the SCADA system was discussed. Facilities and assets such as the new
Transmission Pipeline Project were specifically discussed. The SCADA system
could help to control water flows in the pipeline. The replacement or expansion
of the Tanner Reservoir and the Ione water treatment plants could also benefit
from usage of the system wide technology. Abercrombie stated that “Almost any new asset we have
including the Plymouth pipeline will be integrated into this system.” The
cost of the upgrades for the fiscal years 2005 and 2006 is approximately 1.2
million dollars.
