Who are United Utilities?

United Utilities is responsible for water and wastewater services in the North West of England. From 2025-2030 we will undertake the largest investment in water and wastewater services in the North West in 100 years - that's more than £13 billion worth of investments. Now, more than ever, we need inspiring future talent to help make the North West stronger, greener, and healthier.

Whatever area of our business your interests lie in, our 3-year graduate programme will give you first-class training and support, together with an in-depth understanding of your chosen business area – so that you can develop the skills you need to progress your career as you make a real contribution to the communities we serve. You might enter our scheme as a graduate, but one thing's for sure, before long you'll be heading into your next role as a technical, operational or people leader.

Working in the North West means there's a lot of ground to cover. You could have the opportunity to work in the heart of the Lake District, or you could sample a taste of city life. As well as our main office in Warrington we also recruit for a variety of roles based across the North West; we have 575 wastewater treatment works and 96 water treatment works in areas from Crewe in Cheshire to Carlisle in Cumbria.

Whichever scheme you join, you’ll be at the heart of bringing innovation and positive change to the water industry. Ready to flow into your future with us?

The Role

As part of our 3 year graduate scheme, we will guide you through the IMechE’s monitored professional development scheme, with the ultimate goal of gaining chartership. You will be assigned a mentor who is a Chartered Engineer here at UU to work with and help you tailor your training and development towards your own needs.

Benefitting from the shared knowledge and expertise of working with colleagues across all engineering disciplines, you will build on your university knowledge and develop your engineering skills in water, wastewater and bio resource treatment processes, gaining an understanding of a wide variety of new and innovative technologies, as well as the support that goes into maintaining aging assets.

You will also develop your understanding of company and industry regulations, standards and procedures, as well as working closely with other graduates across our business to help you grow your knowledge in all areas.

Every 6 months we will rotate you through different placements and projects, aiming to develop your mechanical skills in different teams across the business, with growing independence and responsibilities as each placement goes on. This can include placements in:

• Capital Projects
• Better Rivers
• Operational Deployment
• Bioresources
• Hydraulics

At the end of the end of the scheme you will have a guaranteed place on the Mechanical Engineering team.
