Entrant Support

We have compiled a list of resources to support entrants to the fourth round of the Water Breakthrough Challenge (‘Breakthrough 4’) to prepare high quality entries. Please note that the entry period for both streams is now closed and these materials are for reference purposes as the competition continues. If you’re interested in entering, please subscribe to our newsletter to hear about future challenges.

We encourage entrants to carefully read and revisit the key materials for the stream(s) you are entering:

Video support: With our experts

We held a webinar for entrants to Breakthrough 4 on Wednesday 6 September 2023, providing you with an opportunity to learn more about the competition, and ask your questions to the delivery team.

Surgery sessions

We ran one-to-one surgery sessions for those who needed support completing their entry, including clarification on the entry process or the terms and conditions. The surgery sessions were run by the Breakthrough 4 delivery partners. Sessions have now concluded.

Guidance for your pitch recording(s)

In Breakthrough 4, entrants to both streams of the competition will be required to record a pitch as part of their entry.  Pitches for the Catalyst Stream should be 3 mins; and pitches for the Transform Stream should be 5 mins. Pitch recordings have now taken place and entries are closed.

The purpose of the pitch recording is to provide a video explainer to help assessors and judges quickly understand your entry. Within this pitch, you should outline:

  • The problem your solution aims to address and what benefits it will have for customers, society and/or the environment if successful. As a guide, we suggest this should be around a quarter of your pitch.
  • What is innovative about your entry? As a guide, we suggest this should be around a quarter of your pitch.
  • What you intend to do within your entry, focusing on the activities you will undertake. As a guide, we suggest this should be around half of your pitch.

Assuming there is time left in the 15-minute recording slot, we will ask you if you are happy or if you wish to have a second attempt at the recording. If, after the second attempt, you are still not happy, we will offer you an alternative 15-minute slot to try again.

We continue to exclude speaker videos in pitch recordings for Breakthrough 4. We ask that you present slides or other visuals while talking. 

In this round, entrants will not be required to pitch live in front of the judges. However, they will be invited to a live Q&A session to respond to judges’ questions as part of the entry process.

Science Practice Workshops

In previous rounds of the Water Breakthrough Challenge, Science Practice delivered workshops and support to help water companies develop their entries. Although this support is not being offered in Breakthrough 4, recordings from the workshops delivered for Breakthrough 3 are provided below. 

Please be aware that this is advice from previous rounds, and is provided as a guide only – entrants should refer to the most up to date materials when preparing their entry.

Workshop 1: Developing a strong entry 

This workshop covers:

  • Key feedback from judges and assessors in previous years
  • Specific guidance to help you interpret and respond to entry questions and assessment criteria

Please refer to the Recording and Transcript for further information

Workshop 2: Refining your entry for Transform Stage 2

This workshop covers:

  • Major areas of feedback highlighted by judges and assessors in Transform stage 1
  • Deep dive on entry questions specific to Transform Stage 2 and key criteria to focus on
