In September, we brought together Stream’s Advisory Group 1 (Market & User Needs) which comprises subject matter experts from 16 water companies and other industry stakeholders. Co-chaired by Icebreaker One and Northumbrian Water, this group advises and supports the project partners as they commence work on Stream’s Implementation Phase. 

Date: 25 September 2025 10:00-11:30 BST

Location: Online

Co-Chairs: Melissa Tallack (NWL); Charlotte Hillenbrand (IB1) 

Secretariat: Icebreaker One 

Meeting Aims 

  1. Understanding how we shape and deliver future use cases 
  1. Endorsement for Q4 outcomes 

Summary:

  • It was noted that:
    • The only outcome at risk was “Improved data quality and consistency across priority datasets​”, with improvements needed by 29th September to reach the 50% target.
    • On the 29th September, the target had not been reached (45%).
  • It was agreed that the new outcomes are suitable for the next quarter, with the vote being recorded as quorate in the meeting.

Open October

  • It was noted that:
    • The pillar champions asked members to share who they thought should be at Open October.
    • One key area that Stream should be mindful of is how to use the government’s growth strategy as an opportunity to platform the project’s work.
    • As a result, it may be worth inviting individuals from DSIT and DBT.

The Cunliffe Review

  • It was noted that there are 32 potential recommendations that may be relevant to the Stream consortium.
  • It was agreed that some of these recommendations could form the basis of future use cases.
  • It was noted that:
    • Members were concerned about how these use cases may be funded
    • Section 81-82 is a priority
    • The next step would be to theme the recommendations to help further align on which recommendations to prioritise.

CReDO

  • It was noted that:
    • The Product Team is ready to go into the discovery and refinement phase for this cross-sector use case, with the aim to finish the work by the end of Q4.
    • The goal for this use case is to bring the work that CReDO has done with Anglian Water to the wider Stream members, whilst also building out a more comprehensive model.
