Abstract: A method for monitoring the composition and flow rate of wastes discharged from industrial waste water treatment facilities into a common collection system for eventual processing at central waste water treatment plant (WWTP). The information is transmitted to a remote computer and stored in a database, and is then analyzed to prepare reports of particular interest to the receiving WWTP or treatment facility. The system includes a data collection and sending unit, a remote Internet Server computer with a database capable of receiving and storing the collected information, and a web server and reporting unit to analyze the data, prepare reports, and send out alarms. It is a further intention of this invention to correlate the incoming data from said industrial waste water treatment plants with known flows and compositions at said central WWTP to predict the flow and composition of influx water at the WWTP.
