St. Rose Storm Water Pumping Station

Background

The St. Rose Storm Water Pumping Station project involved the construction of a new municipal stormwater pumping station, including all associated site works, structural components, process equipment, mechanical systems, HVAC, plumbing, electrical infrastructure, instrumentation, and industrial automation systems. The project required a dependable control platform capable of supporting efficient stormwater management while ensuring seamless coordination between field devices, local operator interfaces, and the City’s supervisory systems.

Requirement

The project demanded a reliable PLC-based automation solution that could provide accurate process control, local operator monitoring, and seamless integration with the City’s SCADA environment. The system needed to deliver the following:

Reliable PLC and local Operator Interface Terminal (OIT) control.
Comprehensive I/O configuration with analog ranges, digital input status, and alarm management.
SCADA-ready graphics and process visualization.
Complete engineering documentation, testing, and commissioning support for municipal operations.

Project Scope

Valley Integration was responsible for delivering the programming and automation scope for the pumping station, including:

PLC programming using the Emerson PACSystems RX3i platform.
Local Operator Interface Terminal (OIT) development and programming.
Preparation of detailed I/O lists covering analog ranges, alarm parameters, and digital input status.
Development of recommended alarm strategies for the plant paging system in accordance with the Process Control Narrative (PCN).
Preparation of preliminary SCADA graphic display layouts and OIT symbol libraries.
Delivery of Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), and complete project documentation.
