sr-072710-1mCity Council Meeting: July 27, 2010
Agenda Item: j' ~
To: Mayor and City Council
From: Susan Cline, Acting Director of Public Works
Subject: Water and Wastewater Supervisory Control and Data Acquisition
(SCADA) System Upgrade, Installation, and Maintenance
Recommended Action
Staff recommends that the City Council authorize the City Manager to negotiate and
execute an agreement with Beavens Systems Incorporated, a California-based
company, in the amount of $805,788 for three years, with an option to renew for an
additional two years. This is to upgrade, install, maintain, and provide training on the
Supervisory Control and Data Acquisition (SCADA) system for water and wastewater
facilities.
Executive Summary
An industrial process control system known as SCADA is an automated computer
control system that allows. remote operation and control of system equipment and
facilities. Currently, SCADA systems exist for limited water and wastewater facilities on
different software platforms that do not communicate with one another. A system-wide
development and integration of SCADA hardware and software is necessary to enhance
operational efficiencies and control capabilities. Staff recommends Beavens Systems
Incorporated for the project at a cost of $805,788.
Background
The City operates a water production, treatment, and distribution system of over 250
miles of pipeline, the Arcadia and Charnock water treatment facilities, four reservoirs,
ten wells, a wastewater collection system of over 150 miles of pipeline, the Moss
Avenue Pumping Station (MAPS), the Santa Monica Urban Runoff Recycling Facility
(SMURRF), two sewer flow monitoring stations, and five remote urban runoff diversions
to sewer. These facilities are located both in the City and the City of Los Angeles.
Since the 1990's, the City's water and wastewater telemetering and remote control
systems have been limited in their abilities to control many of the critical operating
1
functions and have monitored only basic functions such as reservoir and wet well levels,
pump speeds, and intrusion alarms. Water and wastewater systems operate on two
different software platforms that do not communicate with one another except by
telephone call alarms. On February 25, 2008, the City entered into Agreement No.
1583 with Beavens Systems Incorporated to provide SCADA system design and
improvements for the MAPS and SMURRF facilities to enhance operational efficiencies
for these two sites. On September 16, 2008, Council approved an amendment to
Agreement No. 1583 to include the purchase of the required hardware and software for
SCADA implementation at these two facilities. The remaining water and wastewater
facilities either have no SCADA or continue to operate with outdated telemetering
systems.
biscussion
The accurate and timely reading and recording of water and wastewater flow and
equipment information is crucial to meeting the requirements of operating a modern
water and wastewater system. Currently, response personnel often must travel to the
remotely operated site to determine the nature of the problem when an alarm rings on
the phone. On many occasions, corrections to the operational system could be made
remotely by staff at the Arcadia water treatment facility without having to summon
response personnel and vehicles during non-working hours.
With the success of the SCADA system implemented at MAPS and SMURRF, staff
developed a master plan to upgrade the remaining. water and wastewater facilities onto
a SCADA system. A critical part of this master plan is to integrate all existing SCADA
components onto the same operating system platform for improved communication.
The master plan outlines the design specifications and identifies the required hardware,
software, installation, and training. The integrated SCADA system monitors will reside
at the Arcadia facility and plant operators will have the ability to control remote sites
instantaneously with "real-time" remote monitoring and 24-hour surveillance. To ensure
2
successful implementation of the SCADA master plan, staff requires the assistance of a
qualified industrial process control consultant.
Contractor/Consultant Selection
On May 12, 2010, the City issued a Request for Qualifications for professional services
to upgrade, install, maintain, and provide training on the SCADA system for water and
wastewater facilities with the specifications outlined in the SCADA master plan. The
following five responses were received and reviewed by staff from the Water Resources
Division and the Information Systems Department:
Miles from
Santa Hourly
Bidder Monica Rate
Beavens Systems Incorporated 14 $165
DLT & V 56 $188
DWG & Associates 147 $80
Systems Integrated 127 $175
Transdyn 347 $195
Staff recommends Beavens Systems Incorporated based on its technical competence,
staffing capability, project timeliness, price, quality control, and cost control and
reporting. Beavens Systems Incorporated is also located nearest to the City among the
responding vendors, reducing response time and cost for emergencies. In addition,
other respondents are reluctant to work with the specifications outlined in the City's
SCADA master plan and would most likely ask to provide their own designs for the
project.

Financial Impacts & Budget Actions
The contract amount to be awarded to Beavens Systems Incorporated is $805,788 for.
three years with an option to renew for an additional two years. Of this amount,
$647,388 is for the system-wide upgrades, installation, and training. The remaining
$158,400 is to provide ongoing maintenance of the SCADA system at a cost of $52,800
per fiscal year.
The first-year costs of $700,188 are included in the FY2010-11 budget at the following
accounts:
0259015.589000 SCADA Systems Upgrades $ 323,947
0314022.589000 SCADA Systems Upgrades $ 323,441
25671.560010 SCADA O & M $ 30,000
31661.560010 SCADA O & M $ 22,800
TOTAL $ 700,188
Budget authority for future year annual maintenance costs will be included in the annual
proposed budget.
