From: Lee E. Swain, Director -Department of Public Works
Subject: Supervisory Control and Data Acquisition System Improvements for the
Moss Avenue Pumping Station and Santa Monica Urban Runoff Facility
Recommended Action
Staff recommends that the City Council authorize the City Manager to execute a first
modification to Professional Services Agreement No. 1583 with Beavens Systems
Incorporated to furnish the hardware for the Supervisory Control and Data Acquisition
system for the Moss Avenue Pumping Station and Santa Monica Urban Runoff
Recycling Facility. This modification is not to exceed $65,000, for a revised contract
total of $135,000.
Executive Summary
Beavens Systems Incorporated (Beavens) is currently providing design, selection of
equipment and programming of Supervisory Control and Data Acquisition (SCADA)
upgrades for Moss Avenue Pumping Station (MAPS) and Santa Monica Urban Runoff
Recycling Facility (SMURFF). The SCADA system automatically controls the pumping,
electrical, instrumentation and piping controls and operations of both plants. A contract
modification is required to purchase the hardware and software needed to complete the
installation of the new SCADA system. Funds for this project are available in the Sewer
Pump Plant Maintenance Account.
Discussion
On February 25, 2008, Professional Services Agreement No. 1583 was entered with
Beavens to provide SCADA system improvements for the city's wastewater pumping
station and urban runoff recycling facility. The original scope of work included a
complete turnkey redesign, installation, operation, training and maintenance of a new
SCADA system. The original scope of work did not include the purchase of hardware
and software for SCADA upgrades.

The SCADA upgrades will replace the city's outdated control system with an automated,
networked control system which consists of remote site equipment that gathers data in
real-time to monitor system status, identify current operating needs, and manage
equipment maintenance of city wastewater and urban runoff recycling facilities. The
new SCADA system is equipped with a remote alarm function to indicate when a facility
is operating outside of its parameters; and it alerts operators who can respond
immediately to repair potential problems.
Beavens re-designed a SCADA system that effectively uses communication technology
to help the city better manage its wastewater and urban runoff recycling facilities. The
City plans to integrate its SCADA systems at the various water and wastewater facilities
and monitor and operate from a central control facility, located at the Arcadia Water
Treatment Plant, which has operators working 24 hours per day.
A modification to the existing contract with Beavens is requested to acquire the
necessary hardware and software to complete the installation of SCADA upgrades. The
equipment will be installed and operating by October 2008 with no disruption to sewer
pumping activities.
Financial Impacts & Budget Actions
Funds in the amount of $65,000 are available in Account No. 31661.566450, Sewer
Pump Plant Maintenance, which will be partially reimbursed by the City of Los Angeles
in accordance with the terms of the Amalgamated Sewer System (Hyperion)
Agreement.
