Wastewater that leaks out of defective pipe joints and cracks contaminate ground and surface water and cause a host of other problems, including pipe structure failures due to erosion of soil support, and sinkholes due to erosion of underground soil. Mapping wastewater pipes and detecting leaks has been a huge problem and very labor-intense and costly, many times it is easier to wait for a fail than it is to try to find the leak.
Minibots that can be flushed down any toilet. That collects data from Vibration, Light, and Sound sensors. The Minibots are collected at wastewater plants where an AI is used to analyze the data collected to identify leaks and to even predict them.
Create FoodSafe Minibots that can be used in the same way for drinking water, hundreds of millions of tax dollars are lost in unnecessary water leaks all over the US.
