BACKGROUND:
The City’s water system serves approximately 17,000 customer accounts and a population of 53,000. The City receives imported water through 11 metering facilities (turnouts) from the Calleguas Municipal Water District (CMWD) and distributes it to approximately 36 percent of the City. Customers are served via 16 water storage reservoirs with a total capacity of 35.5 million gallons, 16 booster pump stations, approximately 240 miles of pipeline, and 1,900 fire hydrants.
The City's SCADA system is the central control system for the City's water storage and distribution network. The SCADA system facilitates the reception of information across all water facilities, including pump stations, CMWD turnouts, and reservoirs. This system enables the City's operations staff to efficiently and remotely control, monitor, and adjust operational settings from the City’s Municipal Service Center (MSC) ensuring the uninterrupted high-quality potable water to residents for domestic use and firefighting. Additionally, the SCADA system includes alarms for intrusion, malfunction, and unusual system operations, with notifications sent to standby/on-call personnel after normal working hours.
In 2023, the City upgraded the water SCADA system, which included a new SCADA software package, a new and more reliable communications network, and updated Programmable Logic Controllers (PLCs) at pump stations and reservoirs.
The new SCADA system operates on the Ignition platform, provided by Inductive Automation, Inc. This software captures and stores data such as chlorine and ammonia concentrations, pressures, flows, levels, and equipment status from remote sites using PLCs. It then displays this data and related alarms in near real- time to MSC operations staff via graphical human-machine interface (HMI) screens on computer monitors.
Although the new SCADA system is fully functional, the programming and data presentation on City’s HMI screens were based on requirements defined in 2019.
Since then, the City’s SCADA system’s needs have evolved. Additional system programming is required for the data to be more clearly provided on the HMI screens at the MSC and pump stations and reservoirs. Optimization of the overall system will provide water operations staff the full and highest use of the new system’s features and capabilities to best use the various improvements and new capabilities of the software added since 2019.
DISCUSSION/ANALYSIS:
The optimization project will enhance the existing PLC and SCADA programming to enable local control of remote sites through the current installations. The goal is to increase the reliability of the water SCADA system and improve its operational capabilities to help City staff best manage this critical infrastructure.

AECOM was previously selected through a competitive process for the multi-year design project and the construction management for the upgrade of the City’s SCADA system that was completed in 2023. Additionally, AECOM recently completed a task order providing an assessment report on the current SCADA system optimization options. As such, AECOM is uniquely and highly qualified to perform the proposed optimizations of the system based on their expertise and intimate knowledge of the City’s SCADA system, its software capabilities, and overall City water system configuration and telemetry communication setup.
Staff recommends approving a single-source designation and awarding the Professional Services Agreement to AECOM for $293,050 (Attachment #1), to provide engineering services for optimizing the existing SCADA system.
The following are the estimated project costs:
ITEM COST
SCADA System Assessment (completed – AECOM task order) $ 30,602 SCADA System Optimization (this action – AECOM agreement) $293,050 Extra Services (this action) $ 29,300
City Furnish Materials and Supplies (this action) $ 5,000 Total Project Cost $357,952
The anticipated project completion is July 2025.
This action is not a project as defined under the CEQA because this action will not result in a direct or foreseeable indirect physical change in the environment [14 CCR 15060(c)].
Community Outreach: The project will take place on City properties with no impacts on traffic, general public, or water related services that City provides.
This project meets City Council’s Top Ten Priorities #7, “Public Works + Infrastructure Investments across the community.”
CIP PROJECT PRIORITY: (as outlined in FY 2023-24 and FY 2024-25 CIP Program Budget)
Priority Two – Necessary, but not essential, and there could be consequences if deferred.
