A recent trial aimed at assessing the impact of a behavioural change campaign on water usage has yielded impressive results. Participants who engaged in a doorstep conversation about water saving, committed to a water-saving pledge, and used Wizso tablets managed to save an average of 51.1 litres of water per day.
As part of a Net-Zero water project supported by OFWAT, Affinity Water provided Wizso tablets to participants as a component of their behavioural change campaign. The tablets are designed to mask the colour and odour of urine, eliminating the need to flush after each use, thereby conserving water, reducing carbon emissions, and saving money.
The trial, conducted by Affinity Water—the UK’s largest water-only supplier—in collaboration with Grapeviners, a marketing agency specialising in behavioural change, took place in Bidwell West, a 908-home new housing development in Houghton Regis, Bedfordshire. This trial focused on behavioural interventions without any technological enhancements.
Results showed that participants who combined a doorstep conversation, a water-saving pledge, and Wizso tablet usage saved an average of 51.1 litres of water daily. In comparison, those who only took a pledge saved 32.9 litres per day, while households that received information only managed to save 17 litres per day.
Lina Nieto, Water Neutrality Manager at Affinity Water, commented:
“Bidwell Water Savers was a trial to test the impact of a behavioural change campaign on water usage in Bidwell West. The results have been very positive, and we were delighted to offer Wizso tablets to participants who pledged to reduce their water usage.”
“We have used Wizso in previous research projects and are excited to see its water-saving potential continue to develop.”
Nearly 60% of participants accepted Wizso tablets, intrigued by their innovative potential. The report highlighted that distributing Wizso tablets during the door-knocking campaign significantly boosted water-saving efforts, making these participants the most successful water savers in the trial.
Mark Gilligan, Director of Wizso, added:
“Wizso is a great innovation that will drive long-term water savings for consumers and businesses alike. I am delighted that it has once again delivered positive research results. With further controlled trials, we will gather more robust data on its exact savings and water-saving potential.”
