Your Team  

  

The Environmental and Wastewater Strategy department focuses on developing skilled modellers who can build, assess, and maintain hydraulic, river flow, and water quality models. Through targeted training, team members learn to apply modelling standards, understand system functionality, and deliver high-quality outputs that meet regulatory requirements.  

  

A key part of the role involves working with complex datasets—learning how to source, validate, and manage data to ensure smooth integration into modelling processes. Team members also support technical delivery of modelling projects, including scenario testing and presenting results in clear, audience-friendly formats.  

  

These models play a crucial role in guiding operational, planning, and strategic decisions across the business. By producing accurate and timely urban drainage models, the department helps Yorkshire Water meet its environmental goals and regulatory targets.

  • Learn to identify, validate, and manage key data sources, supporting robust data governance and seamless data integration into modelling workflows.  
  • Support the delivery of hydraulic models across wastewater networks, river systems, and water quality assessments, contributing to a range of environmental and infrastructure projects.  
  • Assist in the technical execution of model usage and maintenance projects, developing practical skills in applying models to real-world scenarios.  
  • Learn the principles of model build, verification, maintenance, and scenario testing, and present outputs in a clear, audience-appropriate format to inform decision-making.  
  • Understand how modelling outputs inform strategic, operational, and planning decisions across the business, enhancing your ability to deliver actionable insights.  
  • Contribute to the production of wastewater, river flow, and water quality models, ensuring urban drainage models meet regulatory standards and are delivered on time and to the required quality.
