Role Purpose
To design, develop, and deliver mechanical engineering solutions for water and wastewater treatment assets, pumping stations, pipework systems, and associated infrastructure. The Mechanical Design Engineer ensures designs are compliant with relevant standards, cost-effective, maintainable, and optimised for reliability and performance.
Mechanical Design & Engineering
Produce detailed mechanical designs for water and wastewater treatment systems, including pumping systems, process equipment layouts, pipework, valves, frameworks, pressure-rated systems, and rotating equipment.
Prepare engineering drawings, specifications, P&IDs, datasheets, and bill of materials.
Carry out design calculations including pump head calculations, flow/pressure sizing, structural loadings (basic), and equipment selection.
Ensure designs comply with water industry standards, specifications, and regulatory requirements.
Support development of 3D models and BIM outputs (where applicable).
Technical Governance & Compliance
Ensure all designs follow CDM regulations, HAZOP/HAZCON considerations, and safe-by-design principles.
Ensure compliance with company design standards and relevant regulations (e.g., WIMES, Pressure Equipment Regulations, BS/ISO standards).
Conduct design risk assessments and participate in technical reviews.
Project Support & Delivery
Work with project managers, civil/ICA/electrical engineers, and external suppliers during project scoping, design, procurement, installation, and commissioning.
Provide technical support during construction, including responding to RFIs and reviewing contractor submissions.
Assist with site surveys, asset assessments, and feasibility studies.
Review and approve vendor drawings and equipment documentation.
Continuous Improvement & Innovation
Identify opportunities for improved asset performance, reduced operational costs, and system optimisation.
Support standardisation of mechanical solutions across the business.
Keep up to date with industry advancements, materials, technologies, and sustainability best practices.
