Refillable Cities: Natalie Fee, Olivia Drake, Thomas Bell and Gus Hoyt aim to reduce dependency on plastic bottled water with a nationwide roll out of an app that pinpoints users to free tap water refill points. The app will capture data and encourage behaviour change through rewards and points that can be exchanged for money off vouchers.

Sustainable Catchments: Steve Buss and Mark Fermor’s idea is to create building models of sustainable catchment opportunities, which will #slowtheflow of flooding. The team, who have catchment expertise and experience in building models, will make information available via subscription or one off reports.

Fix our Water: Morag and Craig Embleton’s smartphone crowdsourcing app lets users inform relevant authorities about water problems, including pollution, flooding, overflowing drains and breach hotspots.

It’s exciting to see people using datasets to create solutions that benefit the wider community. The response to the water challenge has been very encouraging, and again the standard has been extremely high, making it difficult for the judges.

Geovation and OS are proud to support these three new start-up companies with funding and business expertise, helping them turn their ideas into commercial ventures. We were also delighted to have had the opportunity to collaborate on this with Southern Water, United Utilities, Environment Agency and Defra whose release of open datasets coincided with the launch of the challenge.
