The North West is no stranger to rain. But as climate change, urban growth and increasing pressure on our drainage networks continue to reshape the region, how we manage rainwater has never been more important.

At United Utilities, we’re delivering one of the UK’s largest environmental investment programmes through the Big North West Upgrade. This is a once-in-a-generation opportunity to transform how rainwater is managed across our communities, creating greener places, reducing flood risk, improving river health and building resilience for future generations.

We’re looking for an exceptional Rainwater Management Technical Lead to join us on this exciting journey.

This isn’t just another technical role. It’s an opportunity to influence how millions of people experience the environment around them, helping deliver innovative, sustainable solutions that make a real difference across the North West.

Components can include, but are not limited to: swales, rills, soakaways, bio‑retention systems, green roofs, rain gardens, tree pits, ponds and wetlands, basins, infiltration trenches, filter drains, permeable paving, rainwater harvesting, reed beds and surface water separation.
• Explore additional ways for managing rainwater across the system e.g. rainwater harvesting to reduce water consumption, reed beds to help water quality and surface water separation to reduce flooding/spills.
• Drive innovation to make rainwater management solutions more effective, affordable and scalable.
• Use data‑driven insights and analytical software to analyse, review and challenge opportunities and proposals, ensuring optimal solutions are developed and recommended.
• Provide technical leadership across multidisciplinary project teams.
• Collaborate with internal stakeholders, regulators, local authorities, design partners and delivery partners.
• Ensure schemes maximize environmental, social and economic value through a Natural Capital approach.
• Help create sustainable solutions that benefit customers, communities and the environment.

We’re looking for someone who combines technical expertise with a genuine passion for sustainable water management and environmental improvement.
