Towards Better Management of Combined Sewage Systems In New York and New Jersey, and many older areas in the United States, stormwater runoff is cleared from the streets and is dispensed into combined sewers. These combined sewers transport both runoff and domestic waste through pipes that lead to wastewater treatment plants. The problem is that when it rains a couple of tenths of an inch, the runoff enters the sewer and dramatically increases the amount of water and domestic waste in the sewer, exceeding the maximum capacity. This causes the waterwaste mixture to bypass the treatment plant and dispense into the nearest waterway (e.g. the Hudson River). This pollutes the waterway it enters and makes the environment uninhabitable for wildlife it used to support, and unsafe for the people that use it. The introduction of rain barrels  barrels that collect stormwater runoff from the roofs of buildings  can delay the runofffrom going into the sewer, allowing it to be dispensed in a manner that the sewer systems can manage. 1

iCAP: An IoTbased Intelligent Liquid Waste Barrels Monitoring System This paper proposes an intelligent liquid waste barrels monitoring system, named iCAP system, which is based on the Internet of things (IoT) technologies for detecting abnormal opening and dumping of the liquid waste barrels. The proposed system is composed of an inboundoutbound areas management system, intelligent screw caps (named iCAP), and an online cloudbased platform. The inboundoutbound areas management system can provide inboundoutbound areas status management for the liquid waste barrels during transportation. If the intelligent screw cap mounted on the liquid barrel is unscrewed or closed during outdoor transportation, the related messages of such a situation will be uploaded to the proposed online could platform via the SigFox low power wide area networks (LPWAN) wireless communication technology to provide an effectively management and monitoring of liquid waste container transportation. As a result, the proposed system can avoid the problem of environmental pollution, which is caused by illegal waste dumping in the waste treatment process.
