In this era of instant streaming and next-day deliveries, over half the human population of planet Earth still lack adequately managed sanitation facilities.

Ineffective waste treatment services are a significant public health issue in low and middle income countries around the world, with diarrhoea-related diseases leading to over a quarter of a million preventable deaths each year. World Vision is seeking to meet UN Sustainable Development Goal number 6 and achieve adequate and equitable sanitation services for all by 2030. In order to reach this target, the seeker is looking for low-cost, reliable, and efficient methods with which to quantify the number of improved sanitation facilities and track goal progress.

Nevertheless, all solutions will need to demonstrate an identification success rate of over 90% and carry few to nil false-positive recordings.
