This includes LV power distribution, MCCs, ICA interfaces, standby generation, cabling, lighting and integration with process and MEICA systems. The role supports feasibility, outline design, detailed design, construction support and commissioning phases.

Responsibilities

• Develop electrical engineering designs for water and wastewater assets, including LV power distribution systems, variable speed drives (VSDs), pumping systems, chemical dosing and treatment process equipment, earthing and bonding systems, cable calculations, routing and containment, lighting, small power and emergency systems, standby generators and UPS systems (where applicable).
• Perform load schedules, discrimination studies, cable sizing calculations and control philosophies; produce electrical layouts, schematics and equipment specifications; prepare bills of materials.
• Ensure designs comply with relevant standards (BS EN, water industry design specifications, BS 7671, CDM regulations, functional safety requirements) and apply safe‑by‑design principles; participate in HAZOP, HAZCOM and risk reviews.
• Conduct design reviews, value engineering and optimisation; work closely with civil, mechanical, ICA and process engineers to ensure integrated MEICA designs.
• Provide electrical input at all project stages (feasibility, outline design, detailed design, construction) and support procurement by preparing technical specifications and evaluating supplier proposals.
• Provide design support during installation, testing and commissioning; engage with subcontractors, OEMs and supply chain partners.
• Produce high‑quality engineering documentation with version control and traceability; contribute to O&M manuals, asset information and as‑built documentation; meet internal and client quality processes and digital delivery requirements (e.g. BIM Level 2).
• Contribute to the development of standard designs, templates and best practices; support the adoption of new technologies such as smart MCCs, digital monitoring and energy‑efficient solutions; identify optimisation and carbon‑reduction opportunities.

Qualifications

• Degree or HNC/HND in Electrical Engineering or a related discipline.
• Knowledge of BS 7671 and relevant electrical standards; Full UK driving licence.
• Chartered or working towards Chartership (IET or similar).
• Experience designing LV electrical systems and MCCs for treatment works or pumping stations; competence in electrical calculations, discrimination studies and cable sizing.
• Ability to interpret P&IDs, process drawings and equipment data sheets; proficiency with electrical design software/tools such as AutoCAD and SolidWorks.
• Understanding of ICA systems and coordination with control/automation engineers; experience working with major UK water companies and AMP frameworks.
• Knowledge of DNO/G99 requirements for generation or large motor loads; experience with hazardous area classifications (ATEX/DSEAR); understanding of digital design platforms (Revit, BIM 360, CDEs).
• Experience in site surveys, testing, commissioning or inspections of electrical installations.
• Good communication skills and ability to work collaboratively in multidisciplinary teams.
• Personal attributes: strong problem‑solving and analytical mindset, detail‑oriented, proactive, organised, capable of managing multiple projects simultaneously, effective communication and stakeholder management, commitment to safety, sustainability and continuous improvement.
• IOSH/NEBOSH training or other health & safety qualifications; EUSR Clean Water Hygiene; COMPEX (for sites with hazardous areas).
