Case Study: Welsh Water

Welsh Water embarks on proof of concept in water leakage management

Reducing leakage is a major challenge for utility companies across the UK.


In 2019, Dwr Cymru Welsh Water (DCWW) engaged Citi Logik to understand the opportunities that mobile phone network data may offer to reveal the true level of water demand and potential areas of leakage.

A summary:

  • Proof of concept

  • Overcome limitations of census data

  • Use mobile network data to understand theoretical demand at specific times

  • Analyse transient population movements

  • Impact of Covid-19
