Wattr

Wattr is a water sustainability startup focused on reducing water waste through intelligent, real-time feedback technology. Our flagship product is a clamp-on ultrasonic flow sensor designed for showers, providing users with live visual feedback to encourage water-saving behaviours. We aim to help hotels, dormitories, gyms, and high-water-use facilities reduce water consumption without complicated installations or disruptions. We combine precision sensing with behavioural science to empower users to make immediate, meaningful reductions in water use, supporting sustainability goals, lowering utility costs, and promoting smarter urban living.
