Storm Screen MCC Feeder Upgrades at Shieldhall WWTW

We are pleased to share an update on recent upgrade works delivered at Shieldhall Waste Water Treatment Works (WWTW). As part of ongoing improvements to the Storm Screen Motor Control Centre (MCC), two key feeder circuits have now been successfully refurbished to enhance electrical resilience, operational safety and long-term asset performance.

Feeder Upgrade Works

A planned shutdown allowed our engineering team to safely replace the existing 100A fused switches with new 3‑pole 200A fused switches, each complete with a neutral link. This upgrade strengthens the electrical capacity of the storm screen system and supports improved operational reliability.

Scope of Works

• Removal of the existing fused switch assemblies, including backplates, compartment hardware and supply tails
• Installation and torqueing of upgraded supply tails onto the busbar droppers
• Fitting of new plexiglass protection and new 200A fused switch backplates
• Termination and torqueing of new tails into the upgraded 200A fused switches
• Installation of new compartment doors and isolator handles
• Updated labelling and completion of full electrical testing and certification

To accommodate cable routing and ensure safe installation, a new 45‑degree angled gland plate was also installed within the cableway. This modification improved access for incoming cable glanding and provided a more robust long‑term cable management solution.

Outcome

The upgrades were delivered safely and efficiently, in accordance with all required engineering and compliance standards. The installation of new 200A fused switches, enhanced busbar connections and improved cable management has significantly strengthened the reliability, maintainability and future performance of the Storm Screen MCC at Shieldhall WWTW.

This project reflects strong on-site collaboration, high-quality engineering practice and a continued commitment to supporting resilient wastewater infrastructure.
