Overview of the Situation

• Sixth most populated county in Florida

• Most densely populated county in Florida

• Using Wonderware Archestra and InTouch

• Communicate with a combination of radio,

cellular, fiber and microwave

• Homeland Security Audit in late 2015

• Deficient documentation of SCADA system

• No SCADA disaster recovery plan

• Must address items in audit

Pinellas County, FL


Aug 2-4, 2016 – Orlando, Florida, USA

Existing Conditions

• Past practice of awarding to lowest bidder:

• Project specific documentation that wasn’t incorporated into the

overall SCADA system set

• Various levels of quality, format and thoroughness of SCADA

documentation

• Departure of most staff familiar with SCADA system

• Preparing for a major overhaul over the next 3 years.

Project Justification

• Extended downtime that could cause:

• Environmental spills

• Interruption of service

• Contaminated water distribution

• High costs to rewrite software due to insufficient backups

• Meet regulatory and Homeland Security Audit

requirements
