BGEN Advances Intelligent MCC & Control System for Pitts Mill STW into Client Testing Phase

BGEN has reached a key milestone on a project at Pitts Mill Sewage Treatment Works, with a fully integrated intelligent Motor Control Centre (MCC) and control system now progressing through client testing.

Delivered for a major UK water utility under a framework agreement, the project highlights BGEN’s capability in providing end-to-end electrical and control solutions for critical water infrastructure.

Supporting Critical Treatment Processes

The intelligent MCC and control system has been developed to support a wide range of treatment assets across the site, including pumps, blowers, mixers, screens, and sludge processing equipment.

Designed in line with water industry standards, the solution brings together resilient power distribution, advanced motor control, and intuitive operator interfaces to enhance visibility and operational control.

End-to-End Design and Integration

BGEN’s scope includes LV electrical design, MCC manufacture, PLC and HMI software development, and full system integration.

At the core of the solution is a Form 4 Type 2 Intelligent MCC, built in accordance with BS EN 61439-2. The system incorporates intelligent motor starters, variable speed drives, and integrated mains and generator incomers with safety interlocking.

A Rockwell ControlLogix PLC platform has been utilised, alongside a 15” colour touchscreen HMI, providing operators with clear, real-time access to plant status, alarms, and control. All software has been developed in accordance with the client’s control philosophy and approved Functional Design Specification.

Designed for Resilience and Future Growth

The system includes a 400A Generator Connection Box to enable safe and efficient connection of temporary generation during outages or maintenance.

Future flexibility has also been built in, with spare capacity within the MCC and a scalable PLC architecture to support expansion or process changes.

Testing Progress Underway

The project has successfully completed internal testing, as well as Integrated Factory Acceptance Testing (iFAT) and Customer FAT (cFAT), verifying both electrical and control functionality.

The system is now undergoing client testing, representing a key step ahead of final commissioning.

Looking Ahead

Once testing and commissioning are complete, the solution is expected to support improved operational reliability, enhanced visibility for operators, and safe, compliant performance across the treatment works.

By delivering design, manufacture, and integration under a single contract, BGEN continues to provide a streamlined, low-risk approach for its water sector clients.
