TPS offers smart polymer manhole covers that are fitted with an ultra sensor, sigfox module, and microcontroller to detect and report sewage blockages on our Progressive web application. The progressive web application can be used by the general public in reporting clean water leaks from their phones by just taking a picture of the problems which the application saves Geo-location. This allows communities, businesses, and municipalities to have an early detection system that notifies them of sewage blockages that cause pollution, health risks, and contamination of water resources as a result of overflow. 1.Report a potential overflow 2.Tracks to find local nearby plumbers who would quickly arrive to unblock thus preventing sewer pollution affecting poor communities and averting disease risk so associated with sewage overflow. We have created smart devices to service our clientele and contribute immensely in reducing water waste in the country. Currently, 55% of our rivers and dams are currently polluted by overflowing sewage which impacts the environment, health, and development potential of poor communities. And because of poor health, many families are then kept in poverty. One estimate puts the costs at 3.5 billion per year with the problem rising each year by 24.5%.
