PROJECT NAME

SCADA Upgrades/Replacements (CI 5284)

PROJECT DESCRIPTION

• Contractor: CDM Constructors, Inc.
• The general items include:
  • New SCADA (Supervisory Control and Data Acquisition) software, replacement of servers, work stations, and associated network equipment at the MSC; control system overhaul at remote sites; new HMIs and necessary instrumentation for improved monitoring and control.
  • Installation of a 900 MHz radio-based solution with GHz radios as a redundant ring backup
  • Installation of Owner supplied chlorine analyzer units at City reservoir sites.
• Location of Installations and Upgrades includes:
  • MSC (Municipal Service Center)
  • At City Reservoirs, Pumps Stations and at Calleguas Metering Stations (Turnouts)

PROJECT TIMEFRAME

• Project Duration: 500 Calendars Days
• Project Start: April 2021
• Project Completion Date: January 2023

BUDGET/FUNDING

• Total Project Cost: $4.8 Million
• Funding: Water and Wastewater Funds

PROJECT HIGHLIGHTS

• The City’s water system serves approximately 16,900 customer accounts and a population of 51,000. Thousand Oaks receives imported water through ten metering facilities (turnouts) from the Calleguas Municipal Water District (CMWD), and distributes it to approximately 36 percent of the City. The City’s water system consists of 16 water storage reservoirs with a total capacity of 35.5 million gallons, 15 booster pump stations, approximately 240 miles of pipeline, and 1,900 fire hydrants.
• The City’s SCADA system transmits and receives information at its control center at MSC to and from all water facilities including reservoirs, pump stations, and CMWD turnouts. The SCADA system also includes alarms for intrusion, malfunctions, and unusual system operations, including notification to Standby/On-call personnel after normal working hours. Due to the age of our equipment and software installed 1999, SCADA system failures have become more prevalent. Failure in the SCADA system causes operational challenges, additional emergency callouts, and can result in the loss or our ability to provide water service. 

PROJECT BENEFITS

• City’s continuous ability to provide water service.

MAP OF PROJECT AREA

PROJECT IMPACTS

• There will be minimal impact to residents since the SCADA upgrades and replacements to the existing software and hardware are done at the MSC building, reservoir sites, pump stations, and at Calleguas turnouts locations.
• The SCADA radio communications antennas at the turnout location will impact residents nearby due to the visibility of the 2-inch diameter pole and 20 feet in height antennas. At MSC building, reservoir sites, and pump station locations will replace existing antennas at the same locations.
