Peterhead Waste Water Treatment Works

Project Outline

R&A Group were appointed by Scottish Water to deliver the installation of a new electric vehicle (EV) charger at Peterhead Waste Water Treatment Works, supporting Scottish Water’s wider sustainability initiative and transition to an electric fleet.

Prior to installation, R&A Group carried out a detailed site survey to assess existing power availability, site layout and the proposed EV parking location. A full proposal was developed, including cable calculations, site drawings and installation specifications.

The works involved the installation of a Kempower T500 dual CCS charger, along with a matt:e ARD-1-63-TP-SPD surge protection device. The power supply was taken from the site’s main MCC using 25mm 5-core SWA/LSF cabling (63 amps).

A new frame and external GRP housing were installed to accommodate the matt:e unit, feeding into a 63A Commando socket designed for simple connection of the EV charger.

R&A Group’s civil contractor, WM Montgomery & Sons, supplied and installed a new duct route from an existing manhole to the newly constructed charger pad, ensuring a safe and compliant installation.

Project Outcome

The installation was carried out in May 2025, with all works completed safely, efficiently and in accordance with Scottish Water’s operational requirements.

The charger was fully commissioned and connected to Hangar-19 back-office software before project completion, ensuring immediate functionality and seamless integration into Scottish Water’s EV charging network.

All handover documentation, including test certificates and as-built drawings, was issued to Scottish Water within two weeks of completion.

This project forms part of R&A Group’s ongoing support in delivering energy-efficient, future-ready EV infrastructure across Scottish Water’s operational sites.
