CF
Caroline Fraser 28 July 2025

In July, we brought together Stream’s Advisory Group 2 (Technical) which comprises subject matter experts from 16 water companies and other industry stakeholders. Co-chaired by Icebreaker One and Pennon Group, this group advises and supports the project partners as they commence work on Stream’s Implementation Phase.

Meeting Aims 

  1. Members to review and refine the end of phase report findings 
  2. Members to shape the impact and outcomes into playback for their senior stakeholders 

Summary:

  • It was noted that this quarter is about prepping for the next phase of funding.
  • It was noted that activities for this quarter include things like finalising team structure, tooling, as well as the analytics work that has been carried over.
    • It was discussed that the analytics work last quarter focused on what we need and this quarter is making decisions around those needs.
  • It was noted that a final version of the Phase 2 report will be submitted on 25th July after review by the Steering Group. 

End of Phase Report – Group 1 feedback:

  • It was noted that approximately £1.2 million in duplicated project costs have been avoided through shared efforts under Stream.
  • It was noted that several companies avoided consultancy costs of £140–150k by discontinuing plans for separate open data portals and opting to publish via Stream.
  • It was noted that the NSOH data standard was agreed efficiently in just three sessions, attributed to Stream’s facilitation and process maturity.
  • It was discussed that the second year of APR reporting was significantly easier than the first, reducing resource burden and improving staff well-being.
  • It was noted that APIs have enabled real-time regulatory compliance tracking, helping companies replicate Ofwat’s processes and address site-level issues.
  • It was noted that Stream’s joint and individual risk assessments provide layered protection against data breaches, with learnings taken from the energy sector.

End of Phase Report – Group 2:

  • It was noted that Stream provides governance benefits, particularly in making participation straightforward and cost-efficient.
  • It was discussed that the programme has strengthened internal governance and encouraged better data-sharing practices across organisations.
  • It was noted that the platform and support team enable water companies to engage with open data in a way that may not have been possible without Stream.
  • It was suggested that stronger evidence of external impact, such as testimonials from third-party data users, would further demonstrate value.
  • It was noted that Stream fosters a culture of trust and collaboration, supporting wider industry engagement and innovation.

Sharing the report within organisations:

  • It was noted that Stream outcomes and benefits should be shared internally to raise awareness and reinforce the programme’s value.
  • It was discussed that tailored materials are needed:
    • A concise one-slide summary of key benefits for executive engagement.
    • A fuller slide deck to support team discussions and address concerns around data sharing and risk.
  • It was noted that modular, reusable content would help water companies present Stream’s work effectively at forums such as board or risk committees.
  • It was noted that content should highlight Stream’s achievements, sector benefits, and risk management, e.g., the rivers/aquifers example resonated well.
  • It was noted that having a clear route to access presentation materials would support internal communication efforts.
