The Challenge

A regional water authority was operating critical treatment infrastructure on a 15-year-old DCS with no remote monitoring capability and limited alarm management. Operators were manually logging 340+ parameters per shift, and the system had experienced 3 unplanned outages in the previous 18 months.

The Solution

Peunier executed a phased SCADA replacement using Ignition as the core platform, migrating all process control logic, implementing mobile operator access, and deploying a comprehensive alarm rationalization.

Our Approach
01

Legacy System Assessment

Full documentation of existing DCS logic, I/O mapping, and alarm philosophy across 340 monitored parameters.

02

Ignition Platform Development

Built Ignition SCADA system with full P&ID visualization, trend historians, and regulatory reporting templates.

03

Alarm Rationalization

Reduced alarm count from 1,240 to 387 through structured rationalization—improving operator response to genuine process deviations.

04

Mobile & Remote Access

Deployed secure mobile operator interface and remote supervisor access with full audit trail.

05

Cutover & Training

Executed hot-cutover during low-demand period with zero service interruption to distribution customers.
