Summary:

The City of Napa’s Water Division, part of the Utilities Department, is responsible for the operation, maintenance, and ongoing improvement of the municipal drinking water system, which serves more than 85,000 residents in Napa and surrounding areas. The system includes three water treatment plants and fifteen remote sites—primarily pump stations and reservoirs—all of which rely heavily on the City’s control system to ensure continuous, 24/7 water delivery.

To support this critical infrastructure, the City contracts with a systems integrator to provide emergency backup services in the event City staff are unavailable. This includes troubleshooting and repair of SCADA hardware and software during unscheduled outages or system issues. The integrator is required to meet the following response times:

  • Phone/Remote Support (During Business Hours): Response within 2 hours of notification.
  • Onsite Support (During Business Hours): Response to site within 6 hours of notification.
  • Onsite Support (After Hours, Holidays, Weekends): Response to site within 24 hours of notification.

Key Project Elements:

  • Conducted onsite system assessments to strengthen team collaboration with the District and provide actionable recommendations.
  • Replaced legacy ControlNet PLC modules with Ethernet modules to modernize communication protocols.
  • Upgraded ten (10) Allen-Bradley ControlLogix PLC processors at one of the District’s water treatment facilities.
  • Provided secure remote access support to assist the District during events, offering our expertise as needed.
