In 2015 Sanergy was awarded an Mobile for Development (M4D) Utilities grant with SweetSense to install GSM and RFID enabled infrared sensors to record Fresh Life Toilet activity and estimate fill levels. Waste collectors and Fresh-Life Toilet Operators used the sensors to record servicing events and request assistance by swiping RFID tags. A mobile app was also developed to capture waste weight data. Sensor data was recorded from 40 Fresh Life Toilets in informal settlements of Nairobi and used to dynamically predict the frequency of waste collection.
