Design Manager - Water/Wastewater

We are seeking an experienced Design Manager to lead the delivery of water and wastewater design packages across a range of major infrastructure, treatment, network and process-related projects. The successful candidate will manage design activities from concept through detailed design, construction support and completion, ensuring that solutions are technically robust, compliant, buildable and aligned with client requirements, programme, budget and quality standards.
Key responsibilities will include coordinating multidisciplinary design teams, consultants and specialist subcontractors; establishing design scopes, deliverables, interfaces and review processes; and managing design programmes, resources, risks and technical queries. You will lead design reviews, value engineering workshops and constructability assessments, while ensuring that designs comply with relevant legislation, industry standards, health and safety requirements and environmental objectives. The role will also involve reviewing technical documentation, drawings, calculations and specifications, supporting procurement and construction teams, and maintaining effective communication with clients, stakeholders and project leadership. You will be expected to identify and resolve design issues promptly, manage change control and contribute to continuous improvement across project delivery.
Applicants should have substantial experience in design management within the water, wastewater, utilities, civil engineering or related infrastructure sectors. A relevant degree or professional qualification in civil, mechanical, electrical, process engineering or a similar discipline is desirable, along with a strong understanding of water and wastewater treatment processes, networks and associated assets. Experience working within collaborative or design-and-build environments, managing supply chain partners and using common design and document-control systems is advantageous. Strong leadership, communication, organisation and problem-solving skills are essential, as is the ability to manage competing priorities and influence technical decisions. This is an excellent opportunity for a proactive professional who can combine detailed technical understanding with confident management and a strong commitment to safe, sustainable and high-quality project delivery.
